Sensory topography and mapping refers to
Sensory maps are areas of the brain which respond to sensory stimulation, and are spatially organized according to some feature of the sensory stimulation. In some cases the sensory map is simply a topographic representation of a sensory surface such as the skin, cochlea, or retina. In other cases it represents other stimulus properties resulting from neuronal computation and is generally ordered in a manner that reflects the periphery. An example is the somatosensory ma… WebSensory and motor systems of the brain are characterized by orderly, topographic representations or maps of a receptor surface or of body movements. All vertebrates have subcortical representations. Mammals also have representations in neocortex, which vary in number according to the extent of the expansion of neocortex and cortical systems in …

WebA sensory pathway that carries peripheral sensations to the brain is referred to as an ascending pathway, or ascending tract. Each of the various sensory modalities follows a specific pathway through the CNS. Tactile and other somatosensory stimuli activate receptors in the skin, muscles, tendons, and joints throughout the entire body.
WebThe reason is the brain maps each sensory receptor onto the cortex rather than considering the area of the body where the sensor is located. The more receptors there are in a given area of skin, the larger that area’s map will be represented on the surface of the cortex. As a result, the size of each body
