Document Summary

Motor and sensory functions (besides olfactory) are crossed across lobes. We know lateralization based on unilateral brain damage to one hemisphere (eg. brocas patient) During learning, selective existing synapses fire each time an animal responds to the task. Repeated firing strengthens the pathway of synapses, creating a neural bridge that was not previously there. Circuits are created in your brain when you learn something, and they"re strengthened if you use them repeatedly. Split brain: corpus callosum is severed, isolating the right and left hemispheres. Image in right visual field--> left hemisphere: patient unable to use language to identify image. Image in left visual field--> right hemisphere: patient says they see nothing. Imagine in left visual field, pen in hand--> right hemisphere: patient says they see nothing, draws the image. Using left hand: can solve a jigsaw puzzle (right hemisphere and spacial reasoning) Both hands: hands will compete to solve the puzzle in different ways.
