auditory area

Another color area in the brain is next to a primary auditory area, which could explain why some people see colors when they hear sounds.

These motor and auditory areas are important in spoken language processing and production.

In auditory areas, the primary map is tonotopic.

Thus, expert musicians have larger auditory areas.

Thus, the region about the auditory area in the temporal lobe is the auditory association area.

The latter is the fibre bundle connecting the auditory area with Broca's area, which some believe to be crucially involved in the imitation of sounds.

Auditory Area 1, or A1, is for hearing, via the auditory system, the primary auditory cortex.

APD has been defined anatomically in terms of the integrity of the auditory areas of the nervous system.

On a priori grounds we would expect humans to have an auditory area corresponding to temporal visual cortex since speech requires the categorical perception of sounds.

Fibers from the dorsal nuclei were found to project more directly to the primary auditory area, with most axons terminating in layer IIIB.

These included structures in the "limbic system" involved with emotion, motivation and memory formation, and visual and auditory areas of the forebrain involved in processing sensory information.

There are multiple auditory areas (much like the multiple areas in the visual cortex), which can be distinguished anatomically and on the basis that they contain a complete "frequency map."

To test for the auditory areas activated by touch, Schurmann et al. tested subjects while stimulating their fingers and palms with vibration bursts and their finger tips with tactile pressure.

Sounds are parsed according to frequency (i.e., high pitch vs. low pitch) by subcortical auditory areas, and this parsing is reflected by the primary auditory zone of the cortex.

One such study that evaluated the stutter period found that there was over activation in the cerebrum and cerebellum, and relative deactivation of the left hemisphere auditory areas and frontal temporal regions.

That portion of the temporal lobe just beneath the sensory area is reserved for the reception of sound and is therefore the auditory area ("hear" L), or the acoustic area ("hear" G).

In bats, the retinal projection occupies only a thin zone just beneath the surface, but there are extensive inputs from auditory areas, and outputs to motor areas capable of orienting the ears, head, or body.

Primary sensory areas include the visual area of the occipital lobe, the auditory area in parts of the temporal lobe and insular cortex, and the somatosensory area in the parietal lobe.

"Either these things have nothing to do with the hair at all, or the more exciting possibility is that perhaps somatic sensation is so important that the specialized structure is overlapping with processing going on in auditory areas," Dr. Reep said.

Positron emission tomography (PET) and functional magnetic resonance imaging (fMRI) show that musical hallucinations activate a wide variety of areas in the brain including the following: auditory areas, motor cortex, visual areas, basal ganglia, brainstem, pons, tegmentum, cerebellum, hippocampi, amygdala, and peripheral auditory system.
