Brain's Cerebrum: Left vs Right, Four Lobes, Vital Functions
The cerebrum, the largest part of the brain, is divided into four lobes and two hemispheres, each with distinct functions. Pioneering research by Roger W. Sperry, Michael S. Gazzaniga, and Brenda Milner in the 1960s shed light on the unique roles of the 'left brain' and 'right brain'.
The cerebrum, located at the top and front of the brain, is responsible for a wide range of vital functions. It consists of two hemispheres connected by the corpus callosum, which facilitates communication between them. The left hemisphere specialises in language and logical processing, while the right hemisphere excels in visual and intuitive tasks.
The cerebrum can be further divided into four lobes. The frontal lobe manages motor functions, decision-making, and cognitive processes. The parietal lobe interprets sensory impulses, spatial awareness, and sensory integration. The occipital lobe is the visual processing centre, and the temporal lobe handles auditory processing, speech comprehension, and memory.
Damage to different parts of the cerebrum can lead to varied impairments, affecting motor skills, cognitive abilities, sensory perception, speech, and emotional control. Understanding the cerebrum's complex structure and functions, as revealed by Sperry, Gazzaniga, and Milner's groundbreaking work, is crucial for diagnosing and treating neurological disorders.
