Physical exercise in later life promotes ________ in the hippocampus.

Question

Quizplus · Accepted Answer

Physical exercise has been shown to increase the process of neurogenesis in the hippocampus, the region of the brain responsible for learning and memory. This means that new neurons are being created, which can improve brain function and cognitive abilities in later life. A reduction of myelin (option A) would actually have the opposite effect, as myelin is important for neural communication and function. Shortening of telomeres (option B) is a cellular process that is associated with aging and can lead to cell death, so this would not be a positive outcome of physical exercise. Mirror neuron activity (option D) is not typically associated with the hippocampus or exercise in later life.
