Question

In which lobe of the cerebrum are the visual centres located?
A. Frontal lobe
B. Parietal lobe
C. Temporal lobe
D. Occipital lobe

Answer 1

Hint:-The cerebrum is the largest portion of the human brain, it is divided into lobes. It is the most posterior part of the cerebrum. Here the primary visual cortex ( V1 ) is located hence its cortical association area is responsible for vision.

Complete Answer:-“lobes of the brain” refers to the cerebrum. Each and every lobe has specific brain function and different roles. Each lobe of the brain is divided into different sub regions which work together to create full function within the whole of the brain. The four lobes of the brain are :
Frontal lobe: The frontal lobe is located at the front of each cerebral hemisphere and positioned in front of the parietal lobe and above and in front of the temporal lobe. It is involved in reasoning, motor control, emotions, and language.
Parietal lobe: It is located immediately behind the frontal lobe, and is involved in processing information from the body’s senses and essential for sensory information such as touch, temperature, and pain.
Temporal lobe: It is located on the side of the head. Temporal means temple. It is associated with hearing, memory, emotion and some aspects of language.
Occipital lobe: It is located at the back of the brain, and contains the primary visual cortex, which is responsible for interpreting incoming visual information.
The occipital lobe is the visual processing center of the mammalian brain containing most of the anatomical region of the visual cortex. Hence the answer is occipital lobe.

Note:- The cerebral cortex is associated with higher level processes such as consciousness, thought, emotion, reasoning, language and memory. The occipital lobe is required for visual processing. It is involved in the sense of sight; lesions in this area can produce hallucinations.
