Document Summary
Focus on shifts in how individuals improve skills with practice instead of trial-by-trial changes. A skill becomes a motor program or habit. If stimulus is removed during actions sequence, and you still maintain some control, your skill has become a motor program. Skill memories can be memories for events and facts e. g. recipe in a book. Somatosensory and visual are responsible for learning perceptual-motor skills. Brain areas like the basal ganglia, there cerebral cortex, and the cerebellum are all involved. Basal ganglia: close to hippocampus, receive large amount of inputs from cortical neurons. They must remember aspects of past events and rat with hippocampal damage find this very hard, but those with bg damage are able to navigate. Neural activity in bg changes during learning of a perceptual-motor. Cortical representations of skills: regions of cerebral cortex responsible for a certain skill expand with practive of that skill.
