1 Lateral Inhibition and Receptive Fields Lateral Inhibition: –Light on one regions of retinal inhibits ability or adjacent regions to respond to light First studied by Hartline in Limulus Eye This is a compound eye Each bar represents one ommatidium or eyelet

2 How Lateral Inhibition Works Ommatidia 110 units of light 5 units of light Through path is full strength and positive Lateral paths are 0.2 strength and negative

3 Review of Lateral Inhibition What is the effect of light in adjacent ommatidia? How much Lateral Inhibition occurs? Note it is proportional to the intensity of light coming in? What happens to the edge?
