Dissociating intensity from valence as sensory inputs to emotion.

Abstract

In this issue of Neuron, Small and colleagues used fMRI to find evidence for a neural segregation of two dimensions underlying human gustatory experience: intensity and valence. These results join several recent reports that challenge long-held notions regarding amygdaloid representation of negatively valenced events.
