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]
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 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.

This microscope photo provided by the McLean Hospital's Harvard Brain Tissue Resource Center in January 2024 shows cells in the caudate nucleus structure of the brain in a person with Huntington's ...
Marie François Xavier Bichat (/ b iː ˈ ʃ ɑː /; [3] French:; 14 November 1771 – 22 July 1802) [4] was a French anatomist and pathologist, known as the father of modern histology. [ 5 ] [ a ] Although he worked without a microscope , Bichat distinguished 21 types of elementary tissues from which the organs of the human body are composed ...
Analyzing variability in the location of gross anatomical landmarks such as sulci is an accepted method for studying evolutionary hominin brain reorganization. The position of the lunate sulcus in the occipital lobe has been studied in humans, early hominin endocasts, apes, and monkeys by researchers seeking to make inferences about the morphological evolution of brain regions associated with ...
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 ...
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.
