Question Answered step-by-step Dr.Bence has developed a motor learning task, in which rats are… Dr.Bence has developed a motor learning task, in which rats are trained to press levers in a particular sequence. He first lesions a brain area called MIC, and observes that after rat recover from the lesion surgery, they can no longer perform the task. Next he uses a retrograde tracer to discover that neurons in a upstream area, RB, send axonal projections to MIC. He decides to test whether RB is involved in the behavior, so he lesions RB. After rats recover from the lesion surgery, they can still perform the task without any impairment. He is about to conclude that RB is not necessary for the behavior, but to be safe he performs a control experiment first. He uses virus to express Arch in RB neurons, and then implants an optical fiber so that a pulse of light completely silences RB neurons. When he turns on the light just during a trial when the rt is performing the tasking, the rat is severely impaired and cannot press the levers in the rihgt sequence.  What can he conclude about the role of RB in performing this task? Propose a hypothesis that explains why he get different results from the two RB manipulations. Biology Science Physiology PSY 445 Share QuestionEmailCopy link Comments (0)
