Generation of action potential concern with which layer of retina

Answer

**Step-by-Step Solution:**

1. **Understanding the Retina Structure**: The retina is composed of several layers, each with specific functions. The outermost layer is the photopigmented layer, and the innermost layer is the ganglionic layer.

2. **Identifying the Layers**:
- The **outermost layer** is known as the **photopigmented epithelium** where photoreceptor cells (rods and cones) are located.
- The **innermost layer** is called the **ganglionic layer**, which contains bipolar neurons.

3. **Role of Photoreceptors**: When light enters the eye, it first hits the rods and cones in the photopigmented layer. These cells are responsible for detecting light and converting it into electrical signals.

4. **Impulse Transmission**: The rods and cones generate an impulse in response to light. This impulse is then transmitted to the bipolar neurons located in the ganglionic layer.

5. **Action Potential Generation**: The action potential is generated in the bipolar neurons of the ganglionic layer. This is where the electrical signal is amplified and transmitted further.

6. **Transmission to the Central Nervous System**: The action potential generated in the ganglionic layer is sent to the central nervous system via the optic nerve.

7. **Conclusion**: Therefore, the generation of action potential is primarily concerned with the **ganglionic layer** of the retina.
