Functional cerebral asymmetry and performance. I. Reaction time to words and dot patterns as a function of EEG alpha
Behavioral Neuropsychiatry
|April 1, 1976
Abstract:
Alpha activity in left and right hemispheres was recorded while subjects performed in verbal and nonverbal target detection/reaction time tasks. Alpha in the right hemisphere was paradoxically enhanced during the nonverbal task, but RT varied as a function of differential hemispheric arousal in the expected manner--e.g., RT to words was fastest in the performance set showing greatest relative left hemisphere arousal.

01:05Cerebral Hemispheres
The human brain, a complex organ, is functionally divided into two cerebral hemispheres—left and right. These hemispheres are interconnected by a structure of paramount importance, the corpus callosum. This substantial bundle of neural fibers is not just a bridge between the hemispheres but a crucial element for the brain's comprehensive functioning. It enables efficient communication between the two hemispheres, allowing each side of the brain to control and receive sensory and motor...
01:28Lateralization
Brain lateralization refers to the division of mental processes and functions between the two hemispheres of the brain, a phenomenon that optimizes neural efficiency and underpins complex abilities in humans. This specialization allows each hemisphere to perform tasks where it has a comparative advantage, facilitating more refined cognitive capabilities across different domains.
