Week 2: Writing Assignment Answer one of the following questions based on this week's material (one-page typewritten response, double-spaced, due Friday 04/16/10). What do "push" and "pull" refer to in LGN and V1 neurophysiology? According to Hirsch, what is the hypothesized role of inhibitory (smooth) neurons in V1 in terms of simple cell push-pull receptive field properties? What are the advantages of whole-cell recordings that measure intracellular membrane potential (the methodology used by Hirsch), compared to the more standard methodology of extracellular recordings that only look at the action potentials? What do you think is the role of binocular rivalry (besides providing a fascinating experimental

Unformatted text preview: phenomenon for scientists)? In other words, what function could it serve in the brain in natural behavior? Is binocular rivalry a competition in dominance between eyes or between patterns? Provide evidence for either/both. Extra credit (one paragraph, due Friday 04/16/10, up to 20% bonus). Can feedforward push-pull circuitry, as described by Hirsch, support binocular rivalry? Why or why not?
