"Study reveals heightened theta oscillations during memory recall in the brain"

Researchers at the University of Arizona have found that remembering events can trigger theta oscillations in the brain's hippocampus region more than experiencing the actual event. The study challenges the belief that external environment primarily drives these rhythmic signals and suggests that memory generated in the brain is the main driver of theta activity. The findings could have implications for treating patients with brain damage and cognitive impairments, as memory could be used to stimulate theta oscillations and potentially improve memory over time.
