The Insula modulates arousal-induced reluctance to try novel tastes through adrenergic transmission in the rat

open access: yesFrontiers in Behavioral Neuroscience, 2015
Reluctance to try novel tastes (neophobia) can be exacerbated in arousing situations, such as when children are under social stress or in rodents, when the new taste is presented in a high arousal context (HA) compared to a low arousal context (LA).
