January 26th, 2011 in Medicine & Health / Neuroscience Enlarge Each row represents the activity in a neuron at key times during the task. At the time of reward, nearly one-third of adolescent neurons became excited (shown in red) though the level of inhibition (in blue) changed marginally. Adult neurons registered much higher inhibitory activity […]
