Using a brain-computer interface, scientists are beginning to learn why learning is hard.
Researchers are building a case that long before the nervous system works, the brain sends crucial bioelectric signals to guide the growth of embryonic tissues.
Stimulating part of the cortex as needed during learning tasks improves later recall. The finding reveals more about the brain’s memory network and points toward possible therapies.
The neuroscientist Erich Jarvis found that songbirds’ vocal skills and humans’ spoken language are both rooted in neural pathways for controlling learned movements.
Nobel laureate Susumu Tonegawa’s lab is overturning old assumptions about how memories form, how recall works and whether lost memories might be restored from “silent engrams.”
