Eating more ketones may fight against Alzheimer’s disease
Increasing SIRT3 levels with a ketone rich diet may help protect GABAergic interneurons and delay the onset of Alzheimer's disease.... Read More...
Why stress doesn’t always cause depression
Rats susceptible to anhedonia have more serotonin neurons in the ventral dorsal raphe nucleus. However, activating neurons in the central amygdala reduced the serotonin signaling and lowered the effects of social stress.... Read More...
The neurobiological basis of gender dysphoria
A new theory of gender dysphoria claims brain network activity, and not incorrect brain sex may be at the root of symptoms.... Read More...
Environmental enrichment corrects errors in brain development
Environmental enrichment can help correct mismapped neurons in the visual pathways of mice.... Read More...
Adolescent drinking increases anxiety and alcohol abuse risk later in life
Teenage binge drinking is linked to altered gene expression in the brain, specifically the central nucleus of the amygdala. Adolescent rats exposed to alcohol had increased levels of miR-137, resulting in lower expression of proteins essential for healthy neuron growth. During adulthood, these rats displayed higher levels of anxiety and an increased preference for alcohol consumption.... Read More...
Ketamine reduces drinking in male rats, but not females
Ketamine reduced alcohol intake in male rat models of alcohol use disorder but increased the desire for alcohol in low-consumption females.... Read More...
The fetal brain possesses adult-like networks
Features of the functional connectome are present in the fetal brain during the second and third trimesters of pregnancy.... Read More...
How Alzheimer’s disease spreads through the brain
Tau buildup associated with Alzheimer's disease is not, in itself, harmful, but the cellular process it disrupts kills neurons.... Read More...
Brain imaging reveals neural correlates of human social behavior
Brain imaging studies shed new light on social behaviors such as empathy and team flow. The findings provide new understanding of the neural basis of social behaviors and conditions involving social dysfunction.... Read More...
How the brain repurposes unused regions
There is an underlying organization that dictates how the visual cortex is repurposed in blind people, which is not random. ... Read More...
Watching music move through the brain
When people listen to music, the neural tracking of the frontal lobe lags behind the temporal lobe, but during music recall, the frontal lobe precedes that of the temporal lobe. The findings demonstrate bottom-up and top-down processes in the cerebral cortex during music listening and recall. The study provides important insights into how the human brain processes music....
