Exercise 3

Cell A responds best to vertical lines moving to the right. Cell B responds best to 45-degree lines moving to the right. Both of these cells have an excitatory synapse with cell C. How will cell C fire to vertical lines? To 45-degree lines? What if the synapse between B and C is inhibitory?

(a) The receptive field of a simple cortical cell. (b) This cell responds best to a vertical bar of light that covers the excitatory area of the receptive field. (c) The response decreases as the bar is tilted so that it also covers the inhibitory area. (d) Orientation tuning curve of a simple cortical cell for a neuron that responds best to a vertical bar (orientation = 0).
