A new study on mice from the RIKEN-MIT Center for Neural Circuit Genetics has pinpointed 'positive' neurons housed in the back of the amygdala and 'negative' neurons located in the front of the ...

Focusing on a particular section called the basolateral amygdala, researchers show how valence-processing circuitry -- which determines whether we assign good or bad feelings about stimuli -- is ...
