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.
The reasons for this are not fully understood, but it is thought that because the left cerebral hemisphere of the brain controls the right side of the body, the right side is generally stronger; it is suggested that the left cerebral hemisphere is dominant over the right in most humans because in 90–92% of all humans, the left hemisphere is ...
Rightward asymmetry can be seen in the right central sulcus (potentially suggesting increased connectivity between motor and somatosensory cortices in the left side of the brain), lateral ventricle, entorhinal cortex, amygdala and temporo-parieto-occipital area. Sex-dependent brain asymmetries are also common. For example, human male brains are ...
A 2017 image of a sneaker that recently resurfaced falsely claims to show which side of your brain is more dominant depending on the color you see.
Language areas are represented unilaterally in the human brain. [3] In around 95% of right-handers, these brain areas are often located on the left hemisphere, however the proportion reduces in left handers down to around 70%. [2] Therefore 7 in every 100 individuals is right-hemisphered for language and left-hand dominant. [4]
Some variations of right hemisphere dominance are... a) The right hemisphere has more control over emotion than left hemisphere. [n 2] b) The right hemisphere is dominant in emotional expression in a similar way that the left hemisphere is dominant in language. c) The right hemisphere is dominant in the perception of facial expression, body ...
Right-handed people are more skillful with their right hands. Studies suggest that approximately 90% of people are right-handed. [7] [14] Left-handedness is less common. Studies suggest that approximately 10% of people are left-handed. [7] [15] Ambidexterity refers to having equal ability in both hands. Those who learn it still tend to favor ...
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).
