Newborn Brain Cells Show the Way (2 of 2) (IMAGE) Salk Institute Caption This image depicts a Paired Associates Learning (PAL) task, in which mice have to choose a specific object in its correct location on a touch screen to obtain a reward. Adult mice deficient in adult neurogenesis showed a specific impairment in pattern separation, identifying a dentate gyrus-specific function for newborn neurons in the adult brain. Adult born neurons are shown in red the background.
