In what region of the brain is the Planum temporale located?
temporal lobe
THE PLANUM temporale (PT) is located on the posterosuperior surface of the temporal lobe. This brain region is of particular interest because it evinces the most left-right asymmetry in the human brain (left>right in two thirds of all brains).
What is the secondary auditory cortex?
Secondary auditory cortex, which receives projections from the primary auditory cortex, lies along the superior edge of the lateral surface of the temporal lobe thereby surrounding the primary cortex. Different frequencies of sound are represented in particular regions of the auditory cortex.
Where is the Heschl’s gyrus located?
The Transverse Temporal Gyrus (TTG), or Heschl’s gyrus, is a large bump or bumps on the lower bank of the Sylvian (or lateral) fissure, the most posterior-medial half of which is primary auditory cortex (Liegeois-Chauvel et al., 1991).
What is the function of the Wernicke area?
Wernicke area, region of the brain that contains motor neurons involved in the comprehension of speech. This area was first described in 1874 by German neurologist Carl Wernicke.
What does angular gyrus do?
The angular gyrus (AG) is a hub of several networks that are involved in various functions, including attention, self-processing, semantic information processing, emotion regulation, and mentalizing. Since these functions are required in music performance, it is likely that the AG plays a role in music performance.
Where is the auditory cortex?
superior temporal gyrus
The human auditory cortex is situated on the supratemporal plane, and comprises the superior two-thirds of the superior temporal gyrus (STG; Celesia, 1976; Galaburda and Sanides, 1980; Rivier and Clarke, 1997).
Where is the secondary auditory cortex?
the temporal lobe
Secondary auditory cortex (AII) is located more rostrally in the temporal lobe and contains Brodmann area 42.
What does the Heschl’s gyrus do?
Heschl’s gyrus, also known as transverse temporal gyrus, is the gyrus on the upper surface of the temporal lobe that contains the primary auditory cortex (Brodmann areas 41 and 42).
What is the role of Heschl’s gyrus?
This area is not only important for language comprehension, but more importantly, it has a crucial role in speech production, phonologic retrieval, and semantic processing. Heschl’s gyrus is a major component of the posterior portion of the STG and forms the anatomical substrate of the primary auditory area.
