How aerobic exercise enhances neuroplasticity in the brain

A brief but intense period of aerobic exercise immediately reduces GABA, the main inhibitory neurotransmitter in the brain. GABA play an important role in regulating the brain’s capacity to undergo change or neuroplasticity. We observed reduced excitability of GABA-mediated networks in the motor cortex, which may explain findings from previous studies where enhanced neuroplasticity is observed after aerobic exercise. Our findings may have implications for individuals after stroke, where GABA is a promising target for promoting neuroplasticity to promote recovery of motor function.

Kids should pay more attention to mistakes, study suggests -- ScienceDaily

The children then took a fast-moving accuracy task on a computer while their brain activity was recorded. The task: Help a zookeeper capture escaped animals by pressing the spacebar when an animal appeared -- unless it was a group of three orangutan friends, who were helping capture the other animals, in which case they had to withhold their response. Within half-of-a-second after making a mistake, brain activity increases as the person becomes aware of and pays close attention to what went wrong. Essentially, a bigger brain response means the person is focusing more on the error. Children with growth mindsets were significantly more likely to have this larger brain response after making a mistake in the study. In addition, they were more likely to improve their performance on the task after making a mistake.
