What is the function of the somatosensory system?
What is the function of the somatosensory system?
The somatosensory system is the part of the sensory system concerned with the conscious perception of touch, pressure, pain, temperature, position, movement, and vibration, which arise from the muscles, joints, skin, and fascia.
Where is the primary somatosensory area located and what is its function?
The Cutaneous Senses Map onto the Sensory Cortex The primary somatosensory cortex is called S1. This area of the cerebral cortex receives sensory information from the somatic senses, plus proprioceptive senses and some visceral senses. It is located on the postcentral gyrus of the parietal lobe, as shown in Figure 4.3.
What are the functions of the primary and association somatosensory cortex?
Functional Divisions of the Cerebral Cortex
Cortical Area | Function |
---|---|
Primary Somatosensory Cortex | Receives tactile information from the body |
Sensory Association Area | Processing of multisensory information |
Visual Association Area | Complex processing of visual information |
Visual Cortex | Detection of simple visual stimuli |
What happens if the primary somatosensory cortex is damaged?
Finally, somatosensory cortex damage can produce numbness or tingling/prickling sensations in certain parts of the body (i.e. paresthesia). Since the face and hands have the most receptors and take up the largest area of the cortex, they are vulnerable to numbness and/or tingling.
What is the primary somatic sensory cortex?
The primary somatosensory cortex is a region of the brain where nerve signals from the sense of touch are normally received. It is generally located in a part of the brain called the parietal lobe, in a structure called the post central gyrus . A gyrus is a ridge along the surface of the brain;
What is the function of the primary cortex?
The primary cortex is the area in the human brain responsible for the higher brain functions that involve sensory input processing. The auditory cortex receives sound information.
What does somatosensory cortex mean?
The somatosensory cortex is an area of the brain that processes input from the various systems in the body that are sensitive to touch.
Is the somatosensory cortex in the parietal lobe?
The somatosensory cortex is found within the parietal lobes and is essential for processing touch sensations. For instance, the somatosensory cortex helps us to identify the location of a touch sensation and to discriminate between sensations such as temperature and pain.
