The posterior superior temporal sulcus has also been shown to be preferentially activated by lip reading. [26] An area of the right posterior superior temporal sulcus was characterized by a recent study by a stronger response to audiovisual stimuli compared to that of auditory or visual stimuli alone. [27]
It is bounded approximately by the intraparietal sulcus, the inferior postcentral sulcus, the posterior subcentral sulcus and the lateral sulcus. It is bounded caudally by the angular area 39 (H), rostrally and dorsally by the caudal postcentral area 2, and ventrally by the subcentral area 43 and the superior temporal area 22 (Brodmann-1909).
The brain contains four main lobes: temporal lobe, parietal lobe, frontal lobe, and the occipital lobe. The temporoparietal junction lies in the region between the temporal and parietal lobes, near the lateral sulcus (Sylvian fissure). Specifically, it is composed of the inferior parietal lobule and the caudal parts of the superior temporal ...
The superior temporal gyrus (STG [1]) is one of three (sometimes two) gyri in the temporal lobe of the human brain, which is located laterally to the head, situated somewhat above the external ear. The superior temporal gyrus is bounded by: the lateral sulcus above; the superior temporal sulcus (not always present or visible) below;
Neurons in these areas are responsible for sound recognition, and extraction of meaning from sentences. The auditory dorsal stream includes the posterior superior temporal gyrus and sulcus, inferior parietal lobule and intra-parietal sulcus. Both pathways project in humans to the inferior frontal gyrus.
Brodmann area 22 is a Brodmann's area that is cytoarchitecturally located in the posterior superior temporal gyrus of the brain. [1] In the left cerebral hemisphere, it is one portion of Wernicke's area. [1] The left hemisphere BA22 helps with generation and understanding of individual words.
The auditosensory cortex is a differentiated anatomical area within the posterior-medial field of the transverse temporal gyrus of Heschl in the lateral sulcus. [8] The cortex of transverse temporal gyrus of Heschl forms a homogeneous structural region with Brodmann area 22. In contrast to other temporal lobe gyri, the transverse temporal gyrus ...
In contrast to the ventral stream's auditory processing, information enters from the primary auditory cortex into the posterior superior temporal gyrus and posterior superior temporal sulcus. From there the information moves to the beginning of the dorsal pathway, which is located at the boundary of the temporal and parietal lobes near the ...
