Feedback
A Correct. This statement is not true. Neuron loss does not harm overall cognitive ability, though it makes neural processes run more slowly.
B Incorrect. This is a true statement. Neural functions can be retrained, but "exer-cise" of the brain is necessary to do so. Elders learn best when new information is relevant to what is already familiar.
C Incorrect. This is a true statement. Neurons can regenerate in the hippocampus, but this is impeded by stress.
D Incorrect. This is a true statement. Recall of events, including communication, is impaired by a crisis situation or anxiety.
