Question

How do the hemispheres of brain function?

Answer 1

Hint: Hemisphere: left or right half of the brain. lateralization: concept that every hemisphere of the brain is related to specialized functions. longitudinal fissure: deep groove within the brain's cortex. sulcus (plural: sulci) depressions or grooves within the cerebral mantle.

Complete answer:
There is evidence of specialization of function—referred to as lateralization—in each hemisphere, mainly regarding differences in language functions. The left brain controls the proper half the body, and thus the right brain controls the left half the body.
Decades of research on lateralization of function by Michael Gazzaniga and his colleagues suggest that a spread of functions starting from cause-and-effect reasoning to self-recognition may follow patterns that suggest a point of hemispheric dominance (Gazzaniga, 2005). For instance , the left brain has been shown to be superior for forming associations in memory, selective attention, and positive emotions.
The right hemisphere, on the opposite hand, has been shown to be superior in pitch perception, arousal, and negative emotions (Ehret, 2006). However, it should be acknowledged that research on which hemisphere is dominant during a sort of different behaviors has produced inconsistent results, and therefore, it's probably better to consider how the 2 hemispheres interact to supply a given behavior instead of attributing certain behaviors to at least one hemisphere versus the opposite (Banich & Heller, 1998).

Note:
The 2 hemispheres are connected by a thick band of neural fibers referred to as the nerve pathway , consisting of about 200 million axons. The nerve pathway allows the 2 hemispheres to speak with one another and allows for information being processed on one side of the brain to be shared with the opposite side.
