035 On Center, Off Surround Ganglion Cells

In this episode, Leslie Samuel explains the concept of on-center off-surround ganglion cells. The video covers how rods connect to ganglion cells via bipolar and horizontal cells, forming the center and surround of the receptive field. The on-center response results in depolarization and nerve impulses, while the off-surround response leads to hyperpolarization and post-inhibitory rebound. The video also briefly mentions off-center on-surround ganglion cells, which exhibit opposite responses.

What are the main types of cells involved in the connection to ganglion cells as described in the text?

Explain the difference between the center and surround of a ganglion cell's receptive field.

What happens to the membrane potential when rods in the center of the receptive field are stimulated?

Describe the response of a ganglion cell when stimulated in the surround of its receptive field.

What is the significance of the post inhibitory rebound in ganglion cell responses?

What role do horizontal cells play in the response of ganglion cells?

How would the response differ in off center on surround ganglion cells compared to on center off surround ganglion cells?
