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 …

Purpose: Our goal was to use functional MRI (fMRI) to measure brain activation in response
to imagination of odors in humans. Method: fMR brain scans were obtained in 21 normal …

Discriminating between successively presented odors requires brief storage of the first
odor's perceptual trace, which then needs to be subsequently compared to the second odor …

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 …

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 …

Recognizing odors is an important biological function, both in the animal kingdom as well as
for humans. It has been debated whether there exist different forms of human odor memory …

There are two broad claims that can be made to justify a chapter on the neuropsychology of
odor memory. The first is that the study of mental functions and their dissolution in brain …

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

Background The formation of an odor percept in humans is strongly associated with visual
information. However, much less is known about the roles of learning and memory in …

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 …
