Damage to the inferior parietal region including the anterior (supramarginal gyrus) and posterior (angular gyrus) regions resulted in reduced SCR. Damage to the right hemisphere in these regions resulted in a significant (p < 0.001) decrease in SCR while the damage to the left hemisphere of these regions did not (p > 0.05). [n 12]
Damage or lesions to the right hemisphere can result in a lack of emotional prosody [20] or intonation when speaking. [21] The left hemisphere is often involved with dealing of detail-oriented perception while the right hemisphere deals mostly with wholeness or an overall concept of things. [21]
Sometimes the left lobe of the brain is affected and this causes neuropsychological symptoms. The distribution of white matter, the nerve fibers that link diverse parts of the brain, is abnormal. The corpus callosum, the band of nerve fibers, that connects the left and right hemispheres of the brain also gets affected in ASD.
Deprivation from social and emotional care causes severe delays in brain and cognitive development. [39] Studies with children growing up in Romanian orphanages during Nicolae Ceauşescu's regime reveal profound effects of social deprivation and language deprivation on the developing brain. These effects are time-dependent.
This is attributed to a reduced left hemisphere functional specialization for language. Taken from a measure of cerebral blood flow (SPECT) in phonemic discrimination tasks, children with mixed receptive-expressive language disorder do not exhibit the expected predominant left hemisphere activation.

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 ...
Gerstmann syndrome is typically associated with damage to the inferior parietal lobule of the dominant hemisphere. It is classically considered a left-hemisphere disorder, although right-hemisphere damage has also been associated with components of the syndrome. [2] It is named after Jewish Austrian-born American neurologist Josef Gerstmann. [3]
Aprosodia is a neurological condition characterized by the inability of a person to properly convey or interpret emotional prosody. Prosody in language refers to the ranges of rhythm, pitch, stress, intonation, etc. These neurological deficits can be the result of damage of some form to the non-dominant hemisphere areas of language production.
