Look at a colorful photo and there will immediately be activity in the brainstem. That activity in turn creates neuroplasticity, a process that ensures that our brain does not become 'lazy', says clinical neuropsychologist Erik Scherder. According to Scherder, the production of brain cells continues for a lifetime, but we will only benefit from this if we stimulate that production with external stimuli. Creative incentives, such as looking at art, especially help. So looking at art keeps the brain fit.
