Abstract

The GANE (glutamate amplifies noradrenergic effects) model proposed by Mather et al. attempts to explain how norepinephrine enhances processing in highly activated brain regions. Careful perusal of the sparse data available from recording studies in animals reveals that noradrenergic neurons are excited mainly by any change in the environment – a salient, novel, or unexpected sensory stimulus or a change in behavioral contingencies. This begets the “network reset hypothesis” supporting the notion that norepinephrine promotes rapid cognitive and behavioral adaption
