The concept of "right-brained" or "left-brained" individuals is considered a widespread myth which oversimplifies the true nature of the brain's cerebral hemispheres (for a recent counter position, though, see below). Proof leading to the "mythbuster" of the left-/right-brained concept is increasing as more and more studies are brought to light.
Activity exercise-whether one is able to do daily activities normally without any problem, self care activities; Sleep rest-do they have hypersomnia, insomnia, do they have normal sleeping patterns; Cognitive-perceptual-assessment of neurological function is done to assess, check the person's ability to comprehend information
The left and right hemispheres are associated with different functions and specialize in interpreting the same data in different ways, referred to as lateralization of the brain. The left hemisphere is associated with language and calculations, while the right hemisphere is more closely associated with visual-spatial recognition and facial ...
Macroscopically the hemispheres are roughly mirror images of each other, with only subtle differences, such as the Yakovlevian torque seen in the human brain, which is a slight warping of the right side, bringing it just forward of the left side. On a microscopic level, the cytoarchitecture of the cerebral cortex, shows the functions of cells ...
In 2007 the concept of the default mode was criticized as not being useful for understanding brain function, on the grounds that a simpler hypothesis is that a resting brain actually does more processing than a brain doing certain "demanding" tasks, and that there is no special significance to the intrinsic activity of the resting brain.

This is often attributed to differences in "left-" and "right-" brained abilities. One factor that contributes support to the idea that there is a sex difference in brain lateralization is that men are more likely to be left-handed. However, it is unclear whether this is due to a difference in lateralization. [25]

Consequently, the left side of the forebrain mostly represents the right side of the body, and the right side of the brain primarily represents the left side of the body. The contralateral organization involves both executive and sensory functions (e.g., a left-sided brain lesion may cause a right-sided hemiplegia).
