Brain changes in autism traced to specific cell types
Studying brain tissue samples from people with ASD revealed a common set of alterations in genes associated with synaptic communication between neurons. The changes were identified mainly in neurons in the uppermost layers of the neocortex. ... Read More...
Alzheimer’s disease is a ‘double-prion disorder’
Self-propagating amyloid and tau act as prions in the pathology of Alzheimer's disease. Higher levels of the prions in human brain samples were strongly correlated with early onset of Alzheimer's and death at a younger age.... Read More...
To boldly go or anxiously hang back? Mouse Study
Inhibiting VIP interneurons disrupts medial prefrontal cortex representations of anxiety-related information which drive avoidance behaviors. ... Read More...
Had Enough Water? Brain’s Thirst Centers Make a Gut Check
Hydration signals from the gut travel via the vagus nerve to activate thirst neurons in the SFO. These neurons signal to cells in the median preoptic nucleus, driving animals to drink and the kidneys to conserve water in the bloodstream.... Read More...
