Which of the following regions of the brain is incorrectly paired with its function ?

Options

A. Cerebellum - language comprehension
B. Corpus callosum - communication between the left and right cerebral cortices
C. Cerebrum - calculation and contemplation
D. Medulla oblongata - homeostatic control

Answer

To solve the question regarding which region of the brain is incorrectly paired with its function, we will analyze each option provided in the question step by step.

### Step-by-Step Solution:

1. **Identify the Options**: The question presents several regions of the brain along with their supposed functions. We need to evaluate each pair to determine if they are correctly matched.

2. **Evaluate the First Option**:
- **Region**: Cerebellum
- **Function**: Language comprehension
- **Analysis**: The cerebellum is primarily responsible for coordination, balance, and fine motor control. It does not play a role in language comprehension. Therefore, this pairing is incorrect.

3. **Evaluate the Second Option**:
- **Region**: Corpus Callosum
- **Function**: Communication between the left and right cerebral cortices
- **Analysis**: The corpus callosum is indeed responsible for facilitating communication between the left and right hemispheres of the brain. This pairing is correct.

4. **Evaluate the Third Option**:
- **Region**: Cerebrum
- **Function**: Calculation and comprehension
- **Analysis**: The cerebrum is involved in higher brain functions such as reasoning, problem-solving, language comprehension, and memory. This pairing is also correct.

5. **Evaluate the Fourth Option**:
- **Region**: Medulla Oblongata
- **Function**: Homeostatic control
- **Analysis**: The medulla oblongata regulates vital functions such as breathing, heart rate, and blood pressure, which are essential for maintaining homeostasis. This pairing is correct.

6. **Conclusion**: After evaluating all options, the first option (Cerebellum - Language comprehension) is the only incorrect pairing.

### Final Answer:
The region of the brain that is incorrectly paired with its function is **Cerebellum - Language comprehension**.
