A polymodal brain region is an association are whose neurons
have
receptive fields defined by MORE THAN ONE sensory modality (e.g.,
vision,
somatosensations or vision/hearing, etc.) Discuss the adaptive
significance of the
expansion of the polymodal regions PG and STS in humans compared to
other
primates.
Polymodal brain regions are the areas in the right brain with
support the human sense. These are the part of the cerebral cortex
that receives the input from a different type of area including
sensory information and motor areas.
The polymodal brain region in association with the neurons that
involve sensory immortality including vision and hearing involves
brain activation. These are the main sensory organ in which the
external portion of the eye and ear are specialized and they
possess high threshold mechanoreceptors are observed in the form of
poly model receptors. This is also involved in the interpretation
of touch and pain in the body. The occipital lobe is the back part
of the brain which is involved in the division. Neural recognition
can be expressed in the form of complex activity and handling of
stimuli.
The adaptive significance of the expansion of the volume model
region of PG and STS in the human being as compared to primate are
the signals which are responsible for direct projection to the
nucleus. In the human primate, there is prefrontal control of
adaptive significance. Polymodal processing also indicates the
posterior parietal area that is located in the activation of the
brain area which assists in the areas of speech.
