Transverse Temporal Gyrus

The Transverse Temporal Gyrus (TTG), also known as Heschl's gyrus (HG), is a small region of the brain located within the superior temporal gyrus in the Brodmann Area 41 and 42. This structure is part of the cerebral cortex, and is involved in processing auditory information.

Anatomy

The Transverse Temporal Gyrus is found in the temporal lobe, and is the first cortical structure to process incoming auditory information. It is named after Richard Ladislaus Heschl, a 19th-century Austrian anatomist who first described this gyrus.

Function

The primary role of the Transverse Temporal Gyrus is in auditory processing. It receives input from the medial geniculate nucleus of the thalamus, which is the primary relay station for auditory information in the brain. The TTG then processes this information and sends it to other areas of the auditory cortex for further processing.

Clinical Significance

Abnormalities in the Transverse Temporal Gyrus have been associated with several neurological and psychiatric conditions, including schizophrenia, autism, and dyslexia. Research has shown that individuals with these conditions often have differences in the structure or function of the TTG.
