The somatosensory cortex is a region of the brain located in the parietal lobe, responsible for processing sensory information from the body. It interprets tactile stimuli, such as touch, temperature, pain, and proprioception (awareness of body position).
The somatosensory system, or somatic sensory system is a subset of the sensory nervous system. It has two subdivisions, one for the detection of mechanosensory information related to touch, and the other for the nociception detection of pain and temperature. [1] The main functions of the somatosensory system are the perception of external ...
Key Points. A sensory homunculus is a pictorial representation of the primary somatosensory cortex. Somatotopy is the correspondence of an area of the body to a specific point in the brain. Wilder Penfield was a researcher and surgeon who created maps of the somatosensory cortex.
Sensory map is an area of the brain which responds 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 ...
A major somatosensory pathway is the dorsal column–medial lemniscal pathway. The postcentral gyrus is the location of the primary somatosensory area that takes the form of a map called the sensory homunculus.
Somatosensory maps are plastic throughout life in response to altered use or injury. This chapter reviews basic principles and recent findings in primate, human, and rodent somatosensory maps. Keywords: barrel cortex; cortical columns; map plasticity; somatosensory cortex; somatosensory maps; whisker.
This is known as somatotopy and is used to construct maps such as the sensory homunculus, as described in further detail below. Much like the rest of the neocortex, each primary cortex is paired with association cortices to help interpret and assess the initial sensory information delivered.
