Document Summary
Has a cooling pump, and is inserted in the amyglia. Creates a temporary lesion in the brain (renders it inactive) To reach other areas of the brain. Lesioning can be used to remove, damage, or inactive a structure. Electrical stimulation may be used to activate a structure. Intracellular unit recording: membrane potential of a neuron, recording of a single neuron. Extracellular unit recording: firing of a single neuron. Multiple-unit recording: firing of many neurons. Invasive eeg recording: grid of electrodes placed in the brain, recording millions of neurons, non-invasive eeg records over large areas of the cortex, resolution is much lower for normal eeg. Injected described by injection sight: stomach (intragastric, peritoneal cavity (intraperitoneal, ip, large muscle (intramuscular, im, tissue under the skin (subcutaneous, sc, large surface vein (intravenous, iv) Cannula used to administer drug directly to brain. Neural poisons (neurotoxins) selectively target specific nervous system components. Kainic or ibotenic acid destroy cell bodies.
