Neurons found in the cerebral cortex are

Options

A. Myelinated and unipolar
B. Myelinated and multipolar
C. Non-Myelinated and unipolar
D. Non-Myelinated and multipolar

Answer

To solve the question regarding the types of neurons found in the cerebral cortex, we will analyze each option step by step.

### Step 1: Understand the Types of Neurons
Neurons can be classified based on their structure and function. The main types include:
- **Unipolar Neurons**: Have a single process extending from the cell body.
- **Multipolar Neurons**: Have multiple processes (dendrites and one axon) extending from the cell body.
- **Myelinated Neurons**: Have a myelin sheath that insulates the axon, which speeds up signal transmission.
- **Non-myelinated Neurons**: Lack a myelin sheath.

### Step 2: Analyze the Options
1. **Myelinated and Unipolar**:
- The cerebral cortex primarily contains multipolar neurons, not unipolar. Also, many neurons in the cerebral cortex are non-myelinated. Therefore, this option is incorrect.

2. **Myelinated and Multipolar**:
- While the cerebral cortex does contain multipolar neurons, many of them are non-myelinated. Thus, this option is also incorrect.

3. **Non-myelinated and Unipolar**:
- The cerebral cortex does not predominantly contain unipolar neurons; it mainly consists of multipolar neurons. Hence, this option is incorrect.

4. **Non-myelinated and Multipolar**:
- This option correctly describes the majority of neurons in the cerebral cortex. Most neurons here are multipolar and many are non-myelinated.

### Conclusion
After analyzing all the options, the correct answer is:
**Non-myelinated and Multipolar** (Option 4).
