Anatomical terms of neuroanatomy [[[d:|edit on Wikidata]]]

Middle temporal gyrus is a gyrus in the brain on the Temporal lobe. It is located between the superior temporal gyrus and inferior temporal gyrus.

The middle temporal gyrus is bounded by:

• the superior temporal sulcus above;
• the inferior temporal sulcus below;
• an imaginary line drawn from the preoccipital notch to the lateral sulcus posteriorly.

Its exact function is unknown, but it has been connected with processes as different as contemplating distance, recognition of known faces, and accessing word meaning while reading. Some studies indicate that lesions of the posterior region of the middle temporal gyrus, in the left cerebral hemisphere, may result in alexia and agraphia for kanji characters (characters of Chinese origin used in Japanese writing).
