 Because eating and drinking change pressure on the middle ear and eardrum, Brodmann Area 43 may be the primary somatosensory cortex of the eardrum.Additionally, Brodmann Area 43 was found to be functionally active in a study differentiating the roles of the left-frontal and right-cerebellar regions during semantic analysis.Brodmann Area 43 showed a major increase in functional activation by fMRI, when study participants were asked to complete tasks which involved the selection of a verbal response from many possible responses, rather than a sustained search for a verbal response from few possible responses.
