PSYA01H3 Lecture 10: The Brain! (Part 2)
Document Summary
Anything that touches the left side of body is felt by the the right sensory strip and vice versa. If a child is born without a hand, the brain tissue will devote tissue to other parts of the body like the feet, more senses/feedback from the world with the feet rather than the hands. Phantom limb pain is when people who lost their limb feels like they still have the limb and pain or itchiness from the limb they don"t have. The parts of the brain will still become stimulated, even when the part of the body associated with it isn"t there anymore. Even pain is a construct of the brain. The sensory strip has the amount of brain tissue devoted to different parts of body, more on hands and lips. Motor strip has a lot of tissue devoted to the hands for the many functions of the hands and the mouth for language.
