Which part of brain contains such area which are neither clearly sensory nor motor in function?

Options

A. medulla
B. Cerebral cortex
C. Grey matter of cerebrum
D. Both A and C

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks which part of the brain contains areas that do not clearly perform sensory or motor functions.

2. **Identifying Brain Regions**: The options provided are:
- Medulla
- Cerebral Cortex
- Grey Matter of Cerebrum
- Option A and C

3. **Analyzing Each Option**:
- **Medulla**: This part of the brain is primarily involved in autonomic functions and does not have areas that fit the criteria of neither sensory nor motor.
- **Cerebral Cortex**: This region has three main functional areas: sensory, motor, and association areas. The association areas are responsible for integrating information and do not fit strictly into either sensory or motor categories.
- **Grey Matter of Cerebrum**: This consists of neuron cell bodies and is involved in processing information, but it does not specifically denote areas that are neither sensory nor motor.
- **Option A and C**: Since Medulla does not fit the criteria, this option can be disregarded.

4. **Conclusion**: The cerebral cortex contains association areas that are neither sensory nor motor in function. Therefore, the correct answer is the **Cerebral Cortex**.

**Final Answer**: Cerebral Cortex
