This is an area involved in recognizing objects based on information from the tactile senses. The area is located in the parietal cortex, and damage can lead to tactile agnosia. BA 5 is addiotionally sometimes associated with language and talking.
This area is also called the somatosensory association cortex, and as the name suggests, is involved in somatosensory associations. This means that the area is involved in recognizing certain touches, and linking these touches to previous experiences. The area probably only becomes active during unimodal sensory stimulation, meaning that the area only responds to information from the sense of touch.
BA 5 is located in the parietal cortex. It lies directly behind the primary somatosensory areas (BA 1, 2 and 3) and directly in front of BA 7.
This brain region is also involved in language processes according to some studies. These studies have found that speaking a second language generates more activity in this area than speaking one’s native language.
Damage to this brain region is associated with tactile agnosia. With this condition, it is more difficult to recognize and name objects when only using touch. For example, it becomes difficult to recognize size and shape, or structure and texture of objects, the things needed to identify an object by touch.
