UC Berkeley scientists have captured unique images of problem-solving in action by tapping into the minds of mice. The study shows rapid rewiring in the rodents’ frontal brains after they learn by trial and error.
Challenging the idea that addiction is hardwired in the brain, a new UC Berkeley study of mice suggests that even a short time spent in a stimulating learning environment can rewire the brain’s reward system and buffer it against drug dependence.
Neuroscientist Linda Wilbrecht can observe “rewiring” in the living brain using an imaging instrument called a twophoton laser scanning microscope, which has a resolution better than 1/10,000 of an inch.
Cocaine can speedily rewire high-level brain circuits that support learning, memory and decision-making, according to new research from UC Berkeley and UCSF. The findings shed new light on the frontal brain’s role in drug-seeking behavior and may be key to tackling addiction.
