Facial expression control starts in a very old part of the nervous system. In the brain stem sits the facial nucleus, which ...

When a baby smiles at you, it's almost impossible not to smile back. This spontaneous reaction to a facial expression is part ...

To study how a key chemical neuromodulator affects signaling in the brain's cortex, Garrett Neske, PhD, has received a three-year, $300,000 grant from the Whitehall Foundation, a nonprofit ...

Researchers in Japan built a miniature human brain circuit using fused stem-cell–derived organoids, allowing them to watch ...

Researchers identified two brain networks involved in word retrieval -- the cognitive process of accessing words we need to speak. A semantic network processes meaning in middle/inferior frontal gyri, ...

A Japanese research team has successfully reproduced the human neural circuit in vitro using multi-region miniature organs known as assembloids, which are derived from induced pluripotent stem (iPS) ...

To make a deliberate action in a volatile environment, the brain must frequently reassess the value of each action (action-value). Choice can be initially made from the experience of trial-and-errors, ...
