Humans routinely make judgments about olfactory stimuli. However, few studies have
examined the functional neuroanatomy underlying the cognitive operations involved in such …

The functional anatomy of perceptual and semantic processings for odors was studied using
positron emission tomography (PET). The first experiment was a pretest in which 71 normal …

We used positron emission tomography (PET) to investigate brain regions associated with
odor imagery. Changes in regional cerebral blood flow (CBF) during odor imagery were …

The sense of smell has been traditionally assumed to be different from other sensory
modalities in that odors are encoded perceptually, without a semantic component. Recent …

Previous studies have shown activation of right orbitofrontal cortex during judgments of odor
familiarity. In the present study, we sought to extend our knowledge about the neural circuits …

This study describes the functional anatomy of olfactory and visual naming and matching in
humans, using positron emission tomography (PET). One baseline control task without …

Odor identification (OI) tests are increasingly used clinically as biomarkers for Alzheimer's
disease and schizophrenia. The aim of this study was to directly compare the neuronal …

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 …

We showed how cognitive, semantic information modulates olfactory representations in the
brain by providing a visual word descriptor," cheddar cheese" or" body odor," during the …

How the human brain processes the perception, discrimination, and recognition of odors has
not been systematically explored. Cerebral activations were therefore studied with PET …
