Correct option is D
The corpus callosum is a thick band of nerve fibers that connects the left and right hemispheres of the brain, allowing them to communicate with each other.
Information Booster:
- Structure of the Corpus Callosum:
It is made up of white matter and contains approximately 200–250 million nerve fibers.
Divided into regions such as the genu, body, and splenium, which connect specific parts of the brain.
- Importance of the Corpus Callosum:
Plays a vital role in tasks requiring interhemispheric coordination, such as bimanual activities (e.g., typing or playing musical instruments).
Damage to the corpus callosum can lead to disorders like split-brain syndrome, where communication between hemispheres is impaired.
Additional Knowledge:
- Option 1 (Hippocampus): Incorrect because the hippocampus is part of the limbic system and is involved in memory formation, not interhemispheric communication.
- Option 2 (Limbic system): Incorrect as the limbic system is responsible for emotions and motivation, not connecting the brain's hemispheres.
- Option 3 (Cerebellum): Incorrect because the cerebellum controls balance, coordination, and motor activities, not communication between hemispheres.
