Functional localization and lateralization of human olfactory cortex

Article Abstract:

New research has located the regions of the human brain involved in the sense of smell. Positron emission tomography was employed to locate these olfactory regions in 11 test subjects by detecting areas of increased cerebral blood flow after exposure to various odors. Bilateral blood flow where the inferior frontal and temporal lobes join and unilateral flow on the right side of the orbitofrontal cortex bear out previous findings that these parts of the brain comprise the olfactory system.

A family of candidate taste receptors in human and mouse

Article Abstract:

A family of receptors, the TRBs, are specifically expressed in taste receptor cells in the mouth that detect gustatory stimuli. It is anticipated that there will be many further TRB genes beyond the 11 identified on chromosomes 12, 5 and 7.

Genetic tracing reveals a stereotyped sensory map in the olfactory cortex

Article Abstract:

Research is presented concerning the use of genetic tracing to produce a stereotyped sensory map of the olfactory bulb and olfactory cortex in mice. The arrangement of the sensory receptors in the cortex is discussed.
