[{'content': 'Hippocampus lesion \nSelect and explain. \nA. Affects remote memory, B. Affects implicit memory, C. Affects working memory, D. Affects memory transformation from short term to long term', 'role': 'user'}, {'content': 'Answer: D \nExplanation: Working memory areas are connected to the hippocampus and the adjacent parahippocampal portions of the medial temporal cortex.\nIn humans, bilateral destruction of the ventral hippocampus, or Alzheimer’s disease and similar disease processes that destroy its CA1 neurons,\ncause striking defects in short-term memory. So do bilateral lesions of the same area in monkeys.\nHumans with such destruction have intact working memory and remote memory.\nTheir implicit memory processes are generally intact.\nThey perform adequately in terms of conscious memory as long as they concentrate on what they are doing. However,\nif they are distracted for even a very short period, all memory of what they were doing and what they proposed to do is lost.\nThey are thus capable of new learning and retain old prelesion memories, but they cannot form new long-term memories.', 'role': 'assistant'}]
