Technologies such as noninvasive brain stimulation and virtual reality gaming offer insights into how dreams arise and what functions they might serve.
Adult neurogenesis, already appreciated for its role in learning and memory, also participates in mental health and possibly even attention, new research suggests.
Strategies to make lab animals forget, remember, or experience false recollections probe how memory works, and may inspire treatments for neurological diseases.
