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 …

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 …

Olfactory processing in the human brain was examined using positron emission
tomography. Twelve normal volunteers were scanned while smelling pairs of odors: they …

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

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 …

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 …

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 …

In previous positron emission tomography (PET) studies we have shown significant regional
cerebral blood flow (rCBF) increases during olfactory stimulation: unilaterally in the right …

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

Application of positron emission tomography and magnetic resonance imaging has provided
several new insights into various olfactory functions. One is that sniffing and smelling …
