Acetylcholine Release Amps Up Brain’s Plasticity

I met yesterday with a former doctoral student, now a professor at the University of Texas in Dallas, Michael Kilgard. As a research fellow in my UCSF laboratory, Dr. Kilgard studied the conditions under which acetycholine enables brain plasticity—showing among other findings that large scale and highly useful plasticity can be achieved by pairing sensory…
