The field of neurobiology is seeing rapid advances in our understanding of neural circuitry in the brain
Part of this work involves the physical mapping of all synapses (a project dubbed the connectome); another critical advance is in the area of optogenetics, which allows scientists to dissect neural circuits that determine specific behaviors in a range of organisms from fruit flies to monkeys. A. Describe the method of optogenetics. B. Optogenetics has great potential for deepening our understanding of behavior, learning, memory, and cognitive development. However, it is not as likely to be used directly for treatment of problems such as depression or anxiety. Why not? Consider the limitations of the method when answering this question.
