SOURCE: SCIENCE DAILY PSYCHOLOGY FEEDTITLE: Stress can scramble your brain’s internal GPS, MRI study finds
URL: https://www.sciencedaily.com/releases/2026/08/260807035151.htm
Stress may literally scramble the brain’s internal GPS. Researchers found that cortisol, a hormone released during stress, made people significantly worse at navigating a virtual environment and disrupted the precise activity of grid cells, specialized brain cells that help us understand where we are in space. When landmarks were missing, this navigation system nearly stopped functioning, while another brain region appeared to step in and compensate.

~ New preprint, new thread! ~
My former colleagues at UCL Margot Tirole and Dan Bendor (not on Masto) have a new #HippocampalReplay preprint out, to which I contributed a little! Check out our thread and don't hesitate to share and comment!Why do we remember some experiences more than others?
Reactivations of neurons in the #Hippocampus (“replay”), particularly during sleep, may help consolidate memories; but when many experiences occur before going to bed, the brain must sort out what is worth replaying 😴
We investigated whether reward or recency helped prioritize experiences for replay in freely-moving rats. Surprisingly, we found that reward value does not influence replay! Instead, episode recency has a major effect, with the most recent episode being replayed the most!
Check the preprint for more: Time, but not reward, shapes replay-based episodic prioritization

"We now leave #navigation to our #phones. The result: more of us are getting hopelessly lost." #JohnHarris

"#GPS has cut us off from a basic human skill. It’s no wonder #mountain #rescuers are being called out so often. [...] Between 2019 and 2024, the total number of #rescues had increased by 24%, and there was a marked jump among the 18 to 24 age group, among whom callouts almost doubled. [...] across #Britain, there is evidently a mounting problem about the gap between people’s urge to experience wild and open spaces, and their ability to cope when they actually get there. [...] research suggesting that “people with greater lifetime GPS experience have worse #spatialmemory during self-guided navigation”. [...] retested 3 years after the initial research, when they found that “greater GPS use since initial testing was associated with a steeper decline in hippocampal-dependent spatial memory”. The #hippocampus is the part of the brain that deals with navigation: among London taxi drivers, the need to memorise so many geographical details was found to cause it to increase in size. But here were findings that suggested the opposite: reliance on automated #directions reducing people’s capacity to navigate for themselves." #cartography

Interested in how spatial coding is impaired in the medial entorhinal cortex? Join Gustavo Rodriguez on Thursday, 27th June at #fens2024 to hear about it.

A study conducted in Turkey discovered that adding #caffeine to the drinking water of rats exposed to #socialisolationstress can protect them from developing #spatialmemory impairments. While rats who did not drink caffeine with water showed spatial memory impairments as a result of #stress, these impairments were absent in rats who drank water with caffeine.

Long-term #SpatialMemory across large spatial scales in #Heliconius butterflies: Priscila Moura et al. https://www.sciencedirect.com/science/article/pii/S0960982223007595
"Spatial learning is known in #insects, but much of the research has focused on #ants, #bees which live socially. This study provides the first direct evidence of spatial learning in butterflies or #moths, and suggests that complex learning skills may be more common in insects"
