The lateral sulcus (or lateral fissure, also called Sylvian fissure, after Franciscus Sylvius) is the most prominent sulcus of each cerebral hemisphere in the human brain. The lateral sulcus is a deep fissure in each hemisphere that separates the frontal and parietal lobes from the temporal lobe. The insular cortex lies deep within the lateral ...
Perisylvian syndrome is a rare neurological disease characterized by damage to the sylvian fissure (lateral sulcus), an area in the brain involved in language and speech. . The main symptoms are difficulty chewing and swallowing, low muscle tone in the face and tongue, speech and language development disorders, and epile
The superficial middle cerebral vein (superficial Sylvian vein) begins on the lateral surface of the hemisphere. It runs along the lateral sulcus [1] to empty into either the cavernous sinus, [1] [2] or sphenoparietal sinus. [1] It is adherent to the deep surface of the arachnoid mater bridging the lateral sulcus. It drains the adjacent cortex. [2]
The temporoparietal junction (TPJ) is an area of the brain where the temporal and parietal lobes meet, at the posterior end of the lateral sulcus (Sylvian fissure). The TPJ incorporates information from the thalamus and the limbic system as well as from the visual, auditory, and somatosensory systems. The TPJ also integrates information from ...
The Sylvian point is the point on the human skull nearest the Sylvian fissure and is located about 30 millimeters behind the zygomatic process of frontal bone. It is the name given to the stem of the lateral sulcus of the brain.
Functional MRI (fMRI) Blood-oxygen-level dependent imaging: BOLD: Changes in oxygen saturation-dependent magnetism of hemoglobin reflects tissue activity. [26] Localizing brain activity from performing an assigned task (e.g. talking, moving fingers) before surgery, also used in research of cognition. [27] Magnetic resonance angiography (MRA ...
The pars opercularis acts indirectly through the motor cortex to control the motor aspect of speech production, and codes motor programs for this system, while the auditory cortex (via the temporoparietal junction in the lateral sulcus (Sylvian fissure) houses a series of sensory targets. Together, these areas function as a sensory-motor loop ...
The planum temporale is the cortical area just posterior to the auditory cortex (Heschl's gyrus) within the Sylvian fissure. [1] It is a triangular region which forms the heart of Wernicke's area , one of the most important functional areas for language. [ 2 ]
