Document Summary
Individual differences in parent responsiveness: discrete emotions that infants have an how they relate to their physiology, textbook definition of attachment proximity seeking, this idea has evolved. Clara rebello: approach motivation is increased via the nucleus accumbens-ventral pallidum circuit, avoidance motivation is reduced by interrupting threat signals transmitted from the amygdala to the periaqueductal grey (pag, more approach behaviour.

In contrast, older pups learned odor avoidance: postnatal day 10, older rat pups secreted cortisol and released dopamine, thus, avoid odour. If the mother was present, they wouldn"t secrete cortisol not activate the amygdala and learned to approach the odor: but as soon as they were exposed to cortisol then the amygdala was activated.
