I"m supposed to be just imaging PCs. Got a POST PSU fan error. Would have slowed me down in the number of SSDs I have to image. I opened up the PSU, cleaned it out and plugged everything back in. 20 minutes. POST error went away.
I swear this HP just wanted to act up for no good reason.
I wish companies would believe me when I say I can fix hardware AND software issues. 😔

TITLE: Sugar restriction in early life is linked to lower dementia risk and slightly slower brain aging decades later
An analysis of UK Biobank data found that people who were exposed to Britain’s sugar rationing in the womb and during their first years of life had a 27% lower risk of dementia, a 46% lower risk of Alzheimer’s disease, an 11% lower risk of depression, and a 20% lower risk of anxiety compared with people born after rationing ended. Brain scans also suggested slightly slower brain aging in this group. The paper was published in npj Aging.
Neurological and psychiatric disorders such as dementia, depression, and anxiety place a growing burden on individuals, healthcare systems, and societies worldwide. Increasing evidence suggests that some of the factors influencing these conditions may begin acting very early in life, during sensitive periods of brain development.
The first 1,000 days of life, beginning in pregnancy and continuing through infancy, are considered especially important for shaping long-term health. Nutrition is one of the major environmental influences during this period because the developing brain depends heavily on an adequate and balanced supply of nutrients. At the same time, modern diets often expose pregnant women, breastfeeding mothers, and young children to large amounts of added sugar.
This has raised concerns that high sugar intake early in life could have lasting effects on brain development and later mental health. Biological studies suggest that excessive sugar exposure may promote inflammation and disturb systems involved in the body’s response to stress. Poor maternal metabolic health, including elevated blood glucose, has also been associated with a greater risk of conditions such as attention-deficit/hyperactivity disorder and anxiety in children.
Study author Xingji Lian of Guangzhou First People’s Hospital and Guangzhou Medical University in China and colleagues set out to examine whether limited sugar exposure early in life was linked to mental and brain health in older age. Because randomized trials restricting sugar during pregnancy and infancy would be impractical and unethical, the researchers turned to history. The U.K. rationed sugar between 1942 and 1953, limiting intake to levels in line with current dietary guidelines and providing no sugar ration for children under two years of age.
Sugar rationing ended in September 1953, and average adult sugar consumption nearly doubled almost immediately, while intake of other major foods remained stable. This allowed the researchers to treat the policy change as a natural experiment, comparing people conceived while rationing was in place with people conceived after it ended. A previous study using the same natural experiment, published in Science, linked early exposure to rationing to lower risks of type 2 diabetes and high blood pressure.
The researchers drew on the UK Biobank, a large long-term research project that has collected genetic, health, lifestyle, and medical imaging data from about half a million people in the United Kingdom. They examined diagnoses of dementia, Alzheimer’s disease, Parkinson’s disease, depression, and anxiety, along with brain scans that allowed them to estimate each person’s brain age.
The analysis included 60,394 participants born between October 1951 and March 1956. Of these, 38,227 were conceived while rationing was in place (born between October 1951 and June 1954), including 9,963 born between October 1953 and June 1954, who were exposed to rationing only in the womb. The remaining 22,167 participants, born between July 1954 and March 1956, served as the comparison group, and a subset of 9,053 participants without brain disorders had brain scans.
People exposed to rationing both in the womb and after birth had lower risks of dementia, Alzheimer’s disease, depression, and anxiety than the comparison group, after the researchers accounted for factors such as region and month of birth, socioeconomic status, education, family history, and genetic risk scores. Those exposed only in the womb had a 10% lower risk of anxiety but showed no meaningful differences for the other conditions. Rationing was not associated with Parkinson’s disease.
Because participants were only in their late 60s or early 70s by the end of follow-up, the dementia findings rested on relatively few cases: 307 people had been diagnosed with dementia and 123 with Alzheimer’s disease. By comparison, 7,015 had been diagnosed with depression and 4,011 with anxiety.
Longer exposure to rationing after birth was associated with progressively lower risks of depression and anxiety, with the associations becoming more pronounced after six months. For example, participants exposed to rationing for 12 months after birth had a 23% lower risk of depression and a 28% lower risk of anxiety, and the lowest risks were seen in those exposed for 24 months. No such pattern appeared for dementia or Alzheimer’s disease.
The associations were most consistent in women, who showed lower risks of Alzheimer’s disease, depression, and anxiety. In men, the only reliable reduction was for anxiety.
In the brain imaging analyses, people exposed to rationing after birth had brains that looked about 0.39 years, or roughly five months, younger relative to their actual age than those of the comparison group. They also tended to have larger volumes in several deep brain structures, including the hippocampus, thalamus, and putamen, and lower contrast between gray and white matter across much of the cortex, a finding the authors say could reflect several different tissue changes and should be considered preliminary. Exposure only in the womb showed few associations with brain structure.
“These quasi-experimental findings suggest that early-life sugar restriction is associated with attenuated neurobiological aging and lower risks of dementia and psychiatric disorders, suggesting sugar intake as a potential modifiable factor of lifelong brain health,” study authors concluded.
The study contributes to the scientific understanding of the long-term consequences of early nutritional patterns. However, it should be noted that the end of sugar rationing coincided with broader post-war economic recovery, improved maternal healthcare, and changing infant feeding practices, all of which may have independently influenced brain development. Rationing of other foods also ended by July 1954, although consumption of those foods changed only slightly. Because of this, it remains uncertain how much of the observed differences are due to sugar alone.
Individual sugar intake was not measured; exposure was inferred from participants’ birth dates. Diagnoses of depression and anxiety relied partly on self-reports and primary care records, and participants grew up in a post-war, predominantly white British setting that may not reflect the experiences of children today. The authors say the findings need to be replicated in contemporary groups with detailed dietary information before informing clinical or public health recommendations.
The paper, “Early-life sugar rationing, brain aging, and long-term neurodegenerative and psychiatric health outcomes: a population-based natural experiment study,” was authored by Xingji Lian, Amei Chen, Xiaoyan Zhu, Yuyu Huang, Chongzhe Yang, Yan Huang, Meilong Ran, Longyan Yin, and Bing Zhang.

TITLE: LSD pushes brain activity toward a more fractal, complex state, study finds
URL: https://www.psypost.org/lsd-pushes-brain-activity-toward-a-more-fractal-complex-state-study-finds/
A new neuroimaging study indicates that lysergic acid diethylamide, commonly known as LSD, alters human brain activity not just by weakening regular brain waves, but also by speeding them up and making neural signals more complex. The weakening of brain waves and the rise in signal complexity were most pronounced in regions tied to sensory processing, language, emotion, and mental imagery, while areas that control physical movement were largely spared. The findings, published in Communications Biology, also hint that listening to music may dampen rather than amplify these drug-induced changes, though that trend did not hold up after statistical correction.
LSD is a potent psychedelic drug that temporarily alters perception, mood, and the sense of self. Like other classic psychedelics, it works primarily by attaching to and activating serotonin 2A receptors on brain cells, though LSD also binds to dopamine receptors. Studying how this compound changes large-scale brain activity helps scientists understand the biological processes that generate conscious experience.
In human studies, researchers often use magnetoencephalography, or MEG, to track the fast-paced electrical activity of the brain. MEG is a non-invasive procedure where a participant sits with their head inside a helmet-like scanner containing sensitive magnetic detectors. As groups of neurons fire together, they produce tiny magnetic fields that the scanner records at a millisecond-by-millisecond scale.
This electrical activity consists of two main types of signals: rhythmic brain waves and background noise. Rhythmic waves, or neural oscillations, happen when thousands of brain cells fire in a synchronized beat, much like a choir singing a specific note. Two of the most common resting rhythms are alpha waves, which cycle at about 8 to 13 times per second (measured in hertz, or Hz) during relaxed wakefulness, and beta waves, which cycle faster at 15 to 30 Hz and relate to active thinking and alertness. These rhythms ride on top of non-rhythmic, background electrical activity that naturally loses strength at higher frequencies.
Previous psychedelic studies consistently showed that drugs like LSD and psilocybin cause a widespread drop in the strength of alpha and beta waves, a process called cortical desynchronization. Because traditional brain wave analyses measure activity within fixed frequency windows, they can confuse a change in wave speed with a loss of wave strength, or mistake shifts in the background noise for changes in actual rhythms. If an alpha wave speeds up against a background that naturally falls off at higher frequencies, it can look as though the wave lost strength when it actually just shifted to a faster tempo.
Beyond brain wave speed and strength, psychedelics also change the unpredictability and structure of brain signals over time. Scientists measure this using two mathematical tools: Lempel-Ziv complexity, which counts how many new and distinct patterns appear in a signal over time, and Higuchi fractal dimension, which measures how “rough” or self-similar a signal looks when zoomed in and out across different time scales. Higher scores on both metrics indicate richer, less predictable brain activity.
The physical and social environment also plays a major role in shaping a psychedelic experience, with music frequently used in both traditional rituals and modern psychedelic-assisted therapy. For example, a study covered by PsyPost in 2018 showed that LSD heightened brain responses to music across regions tied to auditory processing, emotion, and memory. The new research was led by first author Venkatesh Subramani, who holds a doctorate in neuroscience, and senior author Karim Jerbi, a full professor in the psychology department, both of the Cognitive and Computational Neuroscience Laboratory (CoCo Lab) at the Université de Montréal. The team aimed to separate true changes in brain wave strength from shifts in wave speed and background activity, while also testing how music interacts with these electrical signatures.
“A characteristic effect of classic psychedelics is the desynchronization of rhythmic brain activity (that is, reduced coordination of activity among neural populations) in the alpha (8-13 Hz) and beta (15-30 Hz) bands,” Subramani told PsyPost. “LSD, however, appears somewhat unique because it also speeds up these intrinsic oscillations, by up to 2 Hz for alpha and up to 5 Hz for beta. This acceleration creates an ambiguity: it is unclear whether LSD genuinely desynchronizes these rhythms, or whether the previously reported desynchronization is an artifact of shifts in the spectral peaks.”
To investigate these questions, the researchers analyzed existing MEG data originally collected from 17 healthy volunteers. The experiment used a within-subject, single-blind, placebo-controlled design with a counterbalanced session order, meaning each participant completed two separate scanning sessions spaced 14 days apart without being told which treatment they were receiving. In one session, participants received an intravenous injection of 75 micrograms of LSD, and in the other, they received an inactive saline placebo.
Roughly four hours after the injection, participants underwent MEG brain scans under two different conditions, each lasting seven minutes. In the first condition, they rested with their eyes closed in silence. In the second condition, they kept their eyes closed while listening to ambient music excerpts. The research team used anatomical MRI scans of each participant’s head to map the MEG signals onto 360 distinct regions across the outer surface of the brain.
The authors then used a specialized mathematical tool to separate the rhythmic brain waves from the non-rhythmic background activity in each brain region. Instead of measuring wave strength inside rigid frequency boxes, they tracked the exact peak frequency where each participant’s alpha and beta waves were strongest. They also calculated Lempel-Ziv complexity and Higuchi fractal dimension for each region, and trained machine learning algorithms to see which brain features best distinguished the LSD state from the placebo state.
When the researchers separated the rhythmic waves from the background noise and accounted for shifting frequencies, they found that LSD still caused a genuine drop in the strength of alpha and beta waves. Alpha wave weakening was most pronounced in the temporal lobes, while beta wave weakening occurred broadly across the brain’s surface. However, ignoring the shifting frequencies made the wave weakening look much more widespread than it actually was, confirming that standard methods can inflate the apparent spatial extent of the drug’s effect.
“This study clarifies the ambiguity,” Subramani explained. “It shows that the weakening of oscillations, the usual marker of desynchronization, is genuine even after accounting for the peak shifts, a potential confound.”
Separating the signals also clarified what was happening in the posterior cingulate cortex, a major hub for self-reflection and daydreaming. In standard analyses that mix all signals together, this hub showed large drops in brain wave power under LSD. Once the background noise was removed, those rhythmic differences vanished, indicating that LSD mainly altered the background electrical activity in this region rather than its synchronized waves.
Alongside weakening the waves, LSD systematically sped them up across large portions of the brain. On average, the peak frequency of alpha waves increased by about 2 Hz, while beta wave peaks shifted upward by roughly 5 Hz. Machine learning models trained solely on these frequency shifts were able to correctly identify whether a scan came from an LSD or placebo session with over 82 percent accuracy, where chance would be 50 percent.
The background electrical activity also flattened out across the brain, meaning there was less slow background activity relative to fast activity. At the same time, both Lempel-Ziv complexity and fractal dimension rose substantially, especially in the back of the brain where visual information is processed. Machine learning decoders using these complexity and fractal measures distinguished the LSD state from placebo with over 76 percent accuracy, compared to a 50 percent chance level.
“In plain terms, LSD makes the brain’s main rhythms faster and weaker, and makes its activity more complex,” Subramani noted.
These results align with research covered by PsyPost in 2024, which examined brain activity under microdoses using EEG rather than full psychedelic doses using MEG, and similarly found that LSD increases neural signal complexity. The broader shift away from slower rhythms is also in line with a study covered by PsyPost in March 2026, which examined scalp EEG activity following psilocybin rather than source-resolved MEG following LSD and found that the drug weakened slower theta and alpha waves while strengthening faster beta and gamma activity. That study measured the strength of different frequency bands rather than the speed of individual rhythms, however, and the authors of the new paper note that a clear speeding of alpha and beta peaks has not been consistently observed with psilocybin.
To understand how these electrical changes relate to everyday mental functions, the researchers compared their brain maps against a massive database of over 14,000 prior brain imaging studies. They found that LSD’s effects followed distinct functional hierarchies across different brain systems. Reductions in alpha and beta wave strength, background flattening, and complexity increases were strongest in networks tied to vision, hearing, language, emotion, and mental imagery, while the motor cortex, which controls physical movement, remained largely unaffected.
The weakening and speeding of brain waves did not always line up. The functional systems that showed the largest drop in alpha wave strength, such as auditory and language networks, showed only minimal alpha speeding, while motor and attention networks retained relatively more of their alpha strength but showed the largest increases in alpha speed. In the beta range, the pattern reversed, with the biggest speed-ups occurring where beta strength dropped the most. Because the two effects were not statistically linked across the brain, the authors suggest that wave weakening and wave acceleration may reflect separate processes happening at the same time.
When the researchers examined the effect of music, they did not find any results that survived strict statistical corrections for multiple comparisons across the whole brain. However, uncorrected trends pointed in the opposite direction of what the team initially expected. Instead of boosting the brain effects of LSD, listening to music tended to slightly calm them down, resulting in less background flattening and lower signal complexity compared to experiencing LSD in silence.
The authors suggested that music might act as an external attentional anchor. Building on a 2024 analysis of this same dataset that found psychedelic-induced signal complexity was highest with eyes closed and dropped when attention turned outward, they propose that resting in silence allows the mind to wander freely into unconstrained internal states, whereas focusing on an external structured sound may gently ground and stabilize the brain’s electrical activity.
“Music can be very emotionally powerful, and music and psychedelics have been used together in rituals across many cultures,” Subramani said. “We wanted to formally test how music modulates the way LSD affects the brain. We hypothesized that music potentiates the effect of the drug. Somewhat surprisingly, and albeit not statistically robust, we found the opposite trend: music appeared to reduce the drug effect, which could suggest that the stimulus acts as an anchor that keeps subjects from fully experiencing the psychedelic state.”
“As noted in the paper, this is only hypothesis-generating,” he added. “It calls for studies with more subjects and targeted experimental designs with better controls.” He cautioned that “the music result is exploratory and should not be over-interpreted.”
There are a few things to keep in mind when interpreting these results. The study relied on a relatively small sample of 17 participants, which limits the statistical power needed to detect subtle interactions between the drug and external factors like music. In addition, the MEG scans were recorded about four hours after the LSD injection, roughly two and a half hours after the drug’s subjective effects had peaked. This timing gap may explain why the researchers found few strong links between the brain measurements and participants’ questionnaire ratings.
Looking at music over a single seven-minute average also treats a dynamic song as if it were a static event. Future studies with larger groups could track how brain waves respond to changing musical moments in real time, and use muscle sensors to help rule out muscle activity as a source of the fastest brain signals. Comparing LSD directly with other psychedelics using these same signal-separation methods will also help determine whether speeding up alpha and beta rhythms is a unique signature of LSD’s pharmacology.
The team is already extending their analytical approach to see how these faster brain wave frequencies might affect other common measures of brain communication, such as functional connectivity, which tracks how closely pairs of brain regions coordinate their activity over time.
“This study shows that LSD shifts the oscillatory peaks and that there is a genuine weakening of oscillations beyond these shifts,” Subramani said. “Power is one measure that could be confounded by peak shifts. Another is functional connectivity between pairs of brain regions. We have been actively working on this, and a preprint will be out shortly!”
