Sep 29, 2022 · The human brain is often sectioned (cut) and viewed from different directions and angles. Each point of view provides an altered perspective of the brain that changes the appearance of the major divisions, landmarks, and structures.
Aug 8, 2023 · From the midsagittal section of the brain both white and gray matter can be observed, as well as important spaces such as the third and fourth ventricles. This article will describe the anatomy of the structures visible in the midsagittal section of the brain.

Feb 20, 2024 · The brain consists of billions of neurons (nerve cells) that communicate through intricate networks. The primary functions of the brain include processing sensory information, regulating bodily functions, forming thoughts and emotions, and storing memories.

The human brain is split into two hemispheres, right and left. They are both joined together by the corpus callosum, a bundle of nerve fibers which is located in the middle of the brain. The brain contains cortices such as the visual, motor, and somatosensory cortices. These cortices are all contralateral, meaning that each hemisphere controls the ...
Hemispheric lateralization is the idea that both hemispheres are functionally different and that certain mental processes and behaviors are mainly controlled by one hemisphere rather than the other. There is evidence of some specialization of function, mainly regarding differences in language ability. Beyond that, however, the differences that have...
Split-Brains
The brain’s two hemispheres are joined together by the corpus callosum, a thick bundle of millions of nerve fibers. As an outdated treatment for severe epilepsy, the corpus callosum was sliced, meaning the connections between the two hemispheres were halted. People who undergo this procedure are known as split-brain patients. In the 1960’s neurobiologist Roger Sperry conducted experiments on these split-brain patients to test whether there was a localization of function in the hemispheres. Sp...
Language Lateralization
Although it is known that the lateralization of language functions is in the left hemisphere in the majority of people, this lateralization may be dependent on personal handedness. Szaflarski et al. (2002) used functional magnetic resonance imaging (fMRI) on individuals who were left-hand dominant while they completed language acquisition and non-linguistic tasks. It was found through the fMRI that there was more activation in the right hemisphere of the participants, concluding that they had...
Emotion lateralization
A review of the literature investigating the lateralization of emotion in the brain found that the left and right hemispheres have different functions regarding emotions (Silberman & Weingartner, 1986). It was suggested that the right hemisphere is better at controlling emotional expressions and recognizing emotions and is associated with feelings of negative emotions. Whereas the left hemisphere was specialized in dealing with positive emotions. This implied that different functions of emoti...

There are three standard anatomical planes for visualizing the brain: 1) the coronal or frontal plane; 2) the sagittal plane; and 3) the horizontal or axial plane (Figure 1). The coronal or frontal plane is a vertical plane and splits the brain into front and back sections.
In a sagittal view, the central sulcus runs ventrally about half the length of the brain. The other groove worth noting is the lateral fissure . This one runs roughly along the anterior-to-posterior direction, and curves gently dorsally.

Granule cells are very small, densely packed neurons that account for the huge majority of neurons in the cerebellum. Indeed, cerebellar granule cells account for more than half of the neurons in the entire brain. These cells receive input from mossy fibers and project to the Purkinje cells.
