Hippocampal sulcus: a sulcus that extends from the brain's corpus callosum to the tip of the temporal lobe. Horizontal fissure or Transverse fissure: found between the cerebrum and the cerebellum. Note that a "transverse fissure" can also be found in the liver and lungs. Longitudinal fissure or Medial longitudinal fissure: which divides the ...
The sulci and fissures are shallow and deep grooves respectively in the cortex, that organise the brain into its regions. [2] A sulcus is a shallow groove that surrounds a gyrus or part of a gyrus. A fissure is a deeper furrow that divides the brain into lobes, and also into the two hemispheres as the longitudinal fissure. [4]
The inferior parietal lobule (subparietal district) lies below the horizontal portion of the intraparietal sulcus, and behind the lower part of the postcentral sulcus.Also known as Geschwind's territory after Norman Geschwind, an American neurologist, who in the early 1960s recognised its importance.

Huge numbers of commissural fibers make up the commissural tracts in the brain, the largest of which is the corpus callosum. In contrast to commissural fibers, association fibers form association tracts that connect regions within the same hemisphere of the brain, and projection fibers connect each region to other parts of the brain or to the ...
In neuroanatomy, the parieto-occipital sulcus (also called the parieto-occipital fissure) is a deep sulcus in the cerebral cortex that marks the boundary between the cuneus and precuneus, and also between the parietal and occipital lobes. Only a small part can be seen on the lateral surface of the hemisphere, its chief part being on the medial ...
One part of the brain that is particularly integral to color discrimination is the inferior temporal gyrus. A 1995 study conducted by Heywood et al. was meant to highlight the parts of the brain that are important in achromatopsia in monkeys, however, it obviously sheds light on the areas of the brain related to achromatopsia in humans.
Some interneurons that can be found in more superficial layers can also be found here, including basket cells, bistratified cells, and radial trilaminar cells. Stratum lacunosum (str. lac.) is a thin stratum that too contains Schaffer collateral fibers, but it also contains perforant path fibers from the superficial layers of entorhinal cortex.
It then becomes a distinct invagination that lengthens towards the lateral sulcus and towards the longitudinal fissure [4] at approximately 22 to 23 weeks of gestational age. [ 5 ] Between 2 and 3 years of age, the landmark ‘Pli de Passage Frontoparietal Moyen’ (PPFM), which is a depression buried at the central part of the central sulcus ...
