A substantia innominata-midbrain circuit controls a general aggressive response (cell)
Research about a little-understood brain region that controls all fights in mouse and may drive our angry. Aggression is a key way for survival. Anyone can fight and get angry—that is easy. But to do this to the right person, to the right extent, at the right time, with the right motive, and in the right way, is not for everyone, nor is it easy. This work provides clues about how a little-understood region – posterior Substantia Inominata controls multiple aggressive responses. It regulates the internal state and behavioral activity patterns that together comprise diverse aggressive behaviors. - @ZhenggangZhu
