Affective experience has been described in terms of two primary dimensions: intensity and
valence. In the human brain, it is intrinsically difficult to dissociate the neural coding of these …

Studies of patients with focal brain injury indicate that smell perception involves caudal
orbitofrontal and medial temporal cortices, but a more precise functional organization has …

Arousal and valence are proposed to represent fundamental dimensions of emotion. The
neural substrates for processing these aspects of stimuli are studied widely, with recent …

Although the amygdala is a major locus for hedonic processing, how it encodes valence
information is poorly understood. Given the hedonic potency of odor stimuli and the …

Irritation and negative valence are closely associated in perception. However, these
perceptual aspects can be dissociated in olfaction where irritation can accompany both …

It remains unclear how the brain represents external objective sensory events alongside our
internal subjective impressions of them—affect. Representational mapping of population …

Odor perception is inherently subjective. Previous work has shown that odorous molecules
evoke distributed activity patterns in olfactory cortices, but how these patterns map on to …

Human olfactory perception is notoriously unreliable, but shows substantial benefits from
visual cues, suggesting important crossmodal integration between these primary sensory …

How does selective attention to affect influence sensory processing? In a functional
magnetic resonance imaging investigation, when subjects were instructed to remember and …

Over the last ten years, methods of cerebral imaging have revolutionized our knowledge of
cognitive processes in humans. An impressive number of papers dealing with cerebral …
