Record from a Polygraph Recording and Stimulating Neural Activity Autoradiography: Injection of a radioactive tracer substance that differentially concentrates in areas of interest e.g. 2-D-G = deoxyglucose, high concentrations in areas of high metabolism Animal sacrificed, brain sectioned, radioactivity used to develop photographic film Recording and Stimulating Neural Activity PET Scan Recording and Stimulating Neural Activity Functional MRI Scans Recording and Stimulating Neural Activity Recording and Stimulating Neural Activity Electrical and Chemical Stimulation An Intracranial Cannula Injections of chemicals into brain can be done through an apparatus that is permanently attached to the skull so that animal’s behavior can be observed several times Optogenic Methods Create virus that delivers modified DNA to populations of neurons. Causes them to express light-sensi...
