Document Summary
New technologies for controlling and examining neural circuits. Means of examining involvement of neural circuits in behavior. Infer from analyzing data whether if you have 1-4 neurons and where they are. The action potentials look different depending on where they are. C-fos nuclear protein that indicates recent activity of neurons. Fish (fluorescence in situ hybridization) visualizes mrna expression. Arc shows that if neurons activated recently, they are in the middle, where a bit ago is close to the outside. Excitotoxic lesion caused by glutamate agonist: passing axons spared electrical lesions cause physical damage, including to passing fibers: 2. Temporary inactivation i. e. with microinjection of gaba agonists, glutamate antagonists: 3. Sufficiency stimulate deeply in the brain area: 1. Causes complex actions in the cells of the area: 2. Turnabout is fair play: using viruses as tools: major one is hiv, some genes we have came from viruses.
