In the anterior hippocampus, “neural activity patterns associated with two remembered experiences were more similar if they were closer in space in time and less similar if they were farther away in space and time,” Dr. Per Sederberg, an assistant professor in the department of psychology, told Medical Daily in an email. These results provide compelling evidence, Sederberg and his colleagues say, that a pattern of spatiotemporal organization exists to catalog our memories across a lifetime.
