THIS WEEK’S QUESTION!
Every Sunday, a question will be asked about one of the images from the past week. Be the first to answer correctly, and your blog will be promoted on Monday’s image post and Biocanvas’s main site!
Neurogenesis, the birth of new neurons, occurs throughout adulthood in two locations of the brain. One of these locations is in the hippocampus, which is responsible for processing memories and aiding in learning. If neurogenesis occurs throughout life in this area, then one would expect the hippocampus to increase continuously in size. This, however, is not the case.
How does the hippocampus remain relatively the same size while still having active sites of new cell genesis?
