Document Summary
An experiment to test motor learning uses prism glasses shift all light to one side, so you see your hand shifted from where it actually is. The experimenters get the subjects to throw darts the dot in the graph is on target, while down means too much to the left, and up means too much to the right. The number of throws is on the x axis the prisms shift everything and the throws are way off at first but then they slowly get better as you undergo motor learning. Then immediately after you remove the glasses and your first throw should be in the opposite direction from learning, but you will quickly adapt and return to normal accuracy if the subject is healthy. Climbing bres input semi- permanently alters the synapses of concurrently activated parallel bres, teaching the cerebellum. Climbing fibre (teacher) tells parallel fibres (student) that there is error and we need to fix it.
