A Common Structure Exists for Sensory Cortex Neurons in areas of the sensory cortex (and most other areas of the cerebral cortex) are organized into six layers. The middle layers (III and IV) are the main site of termination of axons from the thalamus (Fig. 22.8). In the primary sensory...
Synonyms Auditory cortex ; Somatosensory cortex ; Visual cortex Definition Areas of the cerebral cortex that receive the first signals from sensory receptors are called primary sensory areas. These areas are separate for each sensory modality, but the major primary sensory regions are those for vision...
Sensory Cortex Includes Primary and Association Areas Axons of sensory relay nuclei of thethalamusproject to a single area or a collection of neighboring areas of thecerebral cortex, thereby providing them with a precise topographic map of the sensory periphery. These parts of the cortex are frequen...
Extending these results to the study of pain causes by the stimulus of the nervous system, he made discoveries about the reception of such signals in the brain and spatial distribution of thesensory areasof the cerebral cortex in different animals. ...
The meaning of SENSORY AREA is an area of the cerebral cortex that receives afferent nerve fibers from lower sensory or motor areas.
neuronal cortical populations, including amongst primary cortical sensory areas, and even during periods in the absence of stimuli, also called spontaneous activity, which seems to resemble properties of spiking-evoked activity in freely moving animals, in both the sensory cortex6–8 and the ...
This finding is incompatible with hypotheses involving extensive feedback from higher areas. Instead, these data suggest that “exogenous” or “stimulus-driven” attentional priority largely arises from bottom-up processes in the early sensory cortex. Results The feedforward account of attentional ...
THALAMUS – structure that consists of a number of nuclei (about 35), which have a function to receive impulses, process them and transmit them into the specificsensoryareas of the cerebralcortex. It receives impulses from other parts of the thalamus and isassociatedwith areas of the forebrain....
Specialized receptors are stimulated by narrow, specific types of energy. However, everyday objects cover areas of skin larger than a lone receptive field and often have complex shapes and textures. The relative position and type of input are segregated in thenervous system, and this anatomical or...
