Yоu аre оn а cаnоe navigating down a river. You know from experience there's a location where the current is choppy and that you need to bear to the opposite coast at that point to avoid rocks. On this particular day you are rowing with the current prior to this point, and the current is particularly strong, such that you encounter the choppy point sooner than usual. A. What visual neurons would be most affected by the current carrying you in a particular direction? Briefly describe their receptive fields and where they might be located. B. What visual neurons would be the most useful for detecting the average direction AND location of the "choppiness" (which has lots of different movement directions within it)? Briefly describe their receptive fields and where they might be located. C. In what structure would you be likely to find a neuron which only starts firing, day or night, when you near the choppy water region? Would this neuron also be active when canoeing on another river, and if so, when or where? D. Parts A and B refer to cells that provide two very different types of information that are critical for navigation. What are they called, and in this situation, why are both important ? What structure is the dominant source of cortical input to the structure in part C? Given this, what pattern of connections would you expect between this structure and the structures in A, B, and C?
