Exam 13: Ways of Exploring

How can single, identifiable neurons be labeled? Choose all that apply.

Two neurons, A and B, are reciprocally connected. To determine how they are connected to each other you stimulate one while recording from the other with the results show in Figure . When you stimulate A, you see the response on the left. When you stimulate B, you see the response in the middle. In addition, when you hyperpolarize A, you see a small hyperpolarization in B. Based on these results, which circuit is correct? Figure (a) (c) (b) (d)

Surprisingly, many people believe that animals other than vertebrates (and even mammals) are not fundamentally important to scientific research, as they are too simplistic or not similar enough to humans. Give one example of an invertebrate, other than Drosophila and C. elegans, that has demonstrated a fundamental concept in neuroscience. Include one of the advantages this animal provided.
