Where is the commissure located?Commissural fibers of the brain, also known as commissural tracts of the brain or commissures are a type of white matter tract that cross the midline, connecting the same cortical area in opposite hemispheres (right-left hemispheric connections 3).14 dec
Where is the anterior and posterior commissure?The anterior commissure connects the olfactory bulbs, amygdaloid nuclei, and the medial and inferior temporal lobes. The posterior commissure fibers connect areas in the occipital lobes, primarily areas concerned with pupillary response and eye movement control.
What crosses in the anterior commissure?The anterior or ventral white commissure is a collection of nerve fibers that cross the midline of the spinal cord and transmit information from or to the contralateral side of the brain.31 jul
What does the anterior gray commissure do?The grey commissure is a thin strip of grey matter that surrounds the central canal of the spinal cord and, along with the anterior white commissure, connects the two halves of the cord.

Is anterior commissure gray or white matter?The anterior commissure (AC) is a transversely oriented commissural white matter tract that connects the two cerebral hemispheres along the midline.

What goes through anterior commissure?Anterior commissure
This commissural pathway mainly interconnects the regions of the two cerebral hemispheres concerned with the olfactory pathway such as the olfactory bulb, the anterior olfactory nucleus, the piriform cortex, the entorhinal area, the anterior perforated substance, and the amygdaloid complex.
Where is the posterior commissure located?The posterior commissure (also known as the epithalamic commissure) is a rounded band of white fibers crossing the middle line on the dorsal aspect of the rostral end of the cerebral aqueduct. It is important in the bilateral pupillary light reflex.
What is the corner of your mouth called?The commissure is the corner of the mouth, where the vermillion border of the superior labium (upper lip) meets that of the inferior labium (lower lip).
Why is the anterior commissure important in brain scanning?Why the commissures? The commissure have become key landmarks, because Talairach and Tournoux chose them to determine the standard alignment of the brain for their famous atlas. To align a scan to Talairach space, a brain has to be set so that the anterior and posterior commissures are on a horizonatal line.
What is the area between your lip and nose called?The philtrum is the midline groove in the upper lip that runs from the top of the lip to the nose. The way the philtrum appears is determined genetically. In some syndromes this grove is shortened. The physical landmarks of the human face are very similar from one face to another.
