🧠 New paper by Cooper et al., who introduce a method to trace #astrocyte #gapjunction networks in vivo and show that astrocytes form selective, plastic networks linking specific #brain regions rather than one diffuse brain-wide syncytium. These networks can span long distances, differ from known #neuronal projections, and reorganize after sensory deprivation:

What's the function of #histamine -1-receptors (H1Rs) on cortical astrocytes? @KiraPoskanzer & co show that astrocytic H1R signaling modulates Ca2+ activity, extracellular adenosine & REM #sleep, revealing a key #astrocyte role in sleep-wake regulation @PLOSBiology https://plos.io/4gRj9Ap

i've seen a few papers in the last 10 years demonstrating direct #astrocyte involvement in a variety of brain functions normally associated with #neurons... does this mean that the definition of the #connectome should be somehow augmented with astrocyte topologies, relative to the neuronal ones?

Alzheimer’s Drug Lecanemab Shields Brain from Free-Roaming Amyloid Fibrils
Amyloid beta protein forms small aggregates that disrupt brain function in Alzheimer’s disease.
Lecanemab, a recently FDA-approved Alzheimer’s treatment, can neutralize these disruptive aggregates, hinting at its potential to slow down the disease’s cognitive decline.#Neuroscience #Brain #Neurology #NeurologicalDiseases #NeurodegenerativeDiseases #Neurodegeneration #Astrocyte #Neuron #Alzheimer #CognitiveDecline #CognitiveDysfunction #MemoryLoss #BetaAmyloid #AmyloidFibrils #Immunotherapy #Lecanemab

Imaging Study Implicates Reactive Astrocyte-Neuron Interaction in Alzheimer’s Cognitive Decline
PET imaging with 11C-acetate and 18F-FDG was used to visualize the reactive astrocyte-induced acetate hypermetabolism and associated neuronal glucose hypometabolism in brains with neuroinflammation and Alzheimer’s Disease.
