If the corpus callosum is removed in mammalian brain then what will be affected :

Options

A. Coordination of Cerebrum
B. Involuntary activity of brain
C. Coordination of Cerebellum
D. Behaviour and emotional disturbances

Answer

**Step-by-Step Solution:**

1. **Understanding the Corpus Callosum:**
- The corpus callosum is a thick band of nerve fibers that connects the left and right cerebral hemispheres of the brain. It facilitates communication between the two sides.

2. **Identifying the Function of the Corpus Callosum:**
- The primary function of the corpus callosum is to coordinate activities between the left and right hemispheres, which is crucial for integrating sensory and motor functions.

3. **Analyzing the Impact of Removal:**
- If the corpus callosum is removed, the communication between the left and right hemispheres is disrupted. This can lead to difficulties in coordination of movements and behaviors that require the integration of information from both sides of the brain.

4. **Evaluating the Options:**
- **Option A: Coordination of cerebra** - This option is correct because the removal of the corpus callosum directly affects the coordination between the two cerebral hemispheres.
- **Option B: Involuntary activity of brain** - This option is incorrect as involuntary activities are primarily controlled by other brain structures, not directly by the corpus callosum.
- **Option C: Coordination of cerebellum** - This option is also incorrect. The cerebellum is responsible for coordinating voluntary movements, and its function is not directly impacted by the corpus callosum.
- **Option D: Behavior and emotional disturbance** - While there may be some behavioral changes, this option is not the most direct effect of corpus callosum removal.

5. **Conclusion:**
- The correct answer is **Option A: Coordination of cerebra**. The removal of the corpus callosum affects the coordination between the left and right cerebral hemispheres, leading to potential behavioral anomalies.
