A cross-section of a mouse brain. The area highlighted red is the midbrain dopamine region that neuroscientists believe controls reward learning. Disclaimer: AAAS and EurekAlert! are not ...

“This novel research paper provides anatomical and physiological evidence for the existence of a long-range inhibitory pathway from the auditory cortex to the amygdala in the mouse brain,” Apicella ...

A ground-breaking study shows the most detailed map of a mammal's brain to date. The 3D blueprints display more than two miles of neural wiring, close to 100,000 nerve cells, and about 500 million ...
