Document Summary
World"s largest dementia research experiment with 2. 4 million downloads. While you play the game, anonymous data is sent to research scientists. We can now damage areas below the surface of the brain. We can also damage the brain more selectively. Neurotoxic lesion- produced by the infusion of a chemical that selectively. Stereotaxic surgery and selective neurotoxins allow us to create animal models of targets neurons or specific types of neurons human disease. Selective ablation of dopaminergic neurons in the substantia nigra. The lesion method is still widely used in neuroscience. Has provided us with great knowledge about the brain. Fibers of passage can sometimes be damaged. Compensation- neuroplastic ability to modify behavior form that used prior to brain damage. As well as removing or inactivating parts of the brain, we can stimulate brain areas. Electrical stimulation of lateral hypothalamus induces eating in rats. Self-stimulation studies- given the opportunity, rats will press the lever to obtain the current.
