Document Summary
Put them in a closet with a lot of stimulation, toys, social interaction. The rats were better at tasks in the lab. Said raising rats in complex environment increase neural complexity. Threw out the idea of absolute stability of brain. One eye could only see vertical lines through the occluders. One eye could only see horizontal lines through the occluders. ~after time, vertical eye was better at discriminating vertical lines, and horizontal eye better for yeah. ~perception of world is influenced by your visual experiences. More line shaped receptive fields in visual cortex. ~whereas in normal cats, 90% of neurons are activated binocularly (by either eye) ~three theories for why this could have happened: Use it or lose it cat is born with a bunch of receptive fields and the ones that aren"t used are lost. Critical period all receptive fields survive, but only have plasticity during a critical period.
