Doodle art illustration describing one process going on in the brain cells responsible for motor movement, more specifically about motor memory (the result of motor learning). Motor memory is stored in specialized neurons called Purkinje cells. The main discovery that the Max Planck Florida Institute for Neuroscience's scientists wished to illustrate is the fact that other type of neurons, called interneurons, communicate with the Purkinje cells in order to control how strong that learning should be in the Purkinje cells.
