The brain is incredibly densely connected. Human cerebral cortex may have as many as *one trillion* connections.
Most of those cortical connections are recurrent, inside each area. What do they do?

Active Filtering: A Predictive Function of Recurrent Circuits of Sensory Cortex | Annual Reviews
Our brains encode many features of the sensory world into memories: We can sing along with songs we have heard before, interpret spoken and written language composed of words we have learned, and reco...

Hi! Do you know anything about the third edition of “Mechanisms of memory” book by David Sweat? Looks like it’s published, but not in a library or in sale… Or, any other suggestions on a book for students learning mechanisms of synaptic plasticity? Thanks 🙏☺️

Newly characterized striatal circuits add twist to ‘go/no-go’ model of movement control
The two novel pathways control dopamine release in opposing ways and may link motivation and mood to action, a new study shows.

The new science of menopause: these emerging therapies could change women’s health
Researchers are exploring how to prolong ovarian life and revisiting hormone replacement therapy — a once routine treatment that has fallen out of favour.

Digital phenotyping from wearables using AI characterizes psychiatric disorders and identifies genetic associations www.cell.com/cell/fulltex... - interesting approach, but a very small sample for GWAS!
Digital phenotyping from wearables using AI characterizes psychiatric disorders and identifies genetic associations
Complex disorders require precise strategies for their characterization. AI-based
digital phenotypes from biosensors can be used to predict psychiatric disorders and
identify GWAS loci.

Identification of the subventricular tegmental nucleus as brainstem reward center
Rewards are essential for motivation, decision-making, memory, and mental health. We identified the subventricular tegmental nucleus (SVTg) as a brainstem reward center. In mice, reward and its predic...
