Presentation Transcript

  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. 110 units of light 5 units of light How Lateral Inhibition Works Ommatidia • 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?
