What does the Planum temporale do?

The left planum temporale (PT), often referred to as Wernicke’s area, is involved in auditory processing and receptive language (Nakada et al., 2001). As such, it has been associated with lexical processing (Bookheimer, 2002).

Is the Planum temporale Wernicke’s area?

The planum temporale is the cortical area just posterior to the auditory cortex (Heschl’s gyrus) within the Sylvian fissure. It is a triangular region which forms the heart of Wernicke’s area, one of the most important functional areas for language.

What hemisphere is the Planum temporale?

left hemisphere
Morphological asymmetries favouring the left hemisphere in the planum temporale (PT) and Heschl’s gyrus (HG) have both been presumed to relate to the typical left-hemisphere dominance for language functions.

Is the Planum temporale in the temporal lobe?

It is well known that the planum temporale (PT) area in the posterior temporal lobe carries out spectro-temporal analysis of auditory stimuli, which is crucial for speech, for example.

What is parietal operculum?

A part of the parietal lobe, the frontoparietal operculum, covers the upper part of the insular lobe from the front to the back. The opercula lie on the precentral and postcentral gyri (on either side of the central sulcus).

What is a Planum?

Medical Definition of planum : a flat surface of bone especially of the skull.

What is Wernicke’s area function?

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. The Wernicke area is located in the posterior third of the upper temporal convolution of the left hemisphere of the brain.

Where is the Planum temporale?

superior temporal gyrus
The planum temporale (PT) is a triangular area situated on the superior temporal gyrus (STG), which has enjoyed a resurgence of interest across several disciplines, including neurology, psychiatry and psychology.

Where is the parietal operculum?

the parietal operculum lies between the inferior portion of the postcentral gyrus and posterior rami of the lateral fissure. The frontal and parietal regions are often grouped together as the frontoparietal operculum.

What is the function of the operculum?

Operculum: The operculum is the bony flap that protects the gills from harm. It opens and closes to allow water to pass over the gills.

What is the Planum sphenoidale?

Planum sphenoidale meningiomas are extra-axial slow-growing tumors arising from the roof of the sphenoid sinus and the area between the optic nerves and the anterior clinoid processes. Enlargement of this meningiomas usually pushes the optic nerves dorsally and caudally causing vision loss as a primary manifestation.
