psych 260 exam 3

destroying part of the brain and evaluating the animals subsaequent behavior; the functions can no longer be preformed in the region that abilation occured

a wound or injury; lesion=experimental abilation

circuts, functions

no

a method of producing brain lesions; intracerebral injection of an excitatory amino acid, such as kainic acid

a method of produciong brain lesions; placebo procedure that duplicates all procedures of a brain lesion except for the step that actually causes the damage to the brain

energy

Brain surgury using a stereotaxic apparatus to position an electrode in a specified position of the brain

a collection of drawings of sections of the brain of a particular animal with measurements that provide coordinates for the stereotaxic surgury

they often miss the mark

provides 3d information about the shape of the surface of a small object

a histological method that labels the axon and terminal buttons or neurons whose cell bodies are located in a particular region

a protein derived from kidney beans and used as an anterograde tracer; taken up by dendrites and cell bodies and carried to the ends of the axons

they take advantage of the immune reaction; a histological method; antibodies bond with a dye molecule to indicate the presense of particular proteins of peptides

a histological method that labels cell bodies that give rise to the terminal buttons that form synapses with cells in a particular region

retrograde labeling dye that is taken up by the terminal buttons and then carried back to the cell bodies

neurons, patterns of activity

an electrical brain potential recorded by placing electrodes on the scalp; record electrical patterns of electrical activity

a procedure that detects groups of synchronously activated neurons by means of the magnetic field induced by their electrical activity; ueses an array od SQUIDs

A very fine electrode, generally used to record activity of individual neurons

recording of the eectrical activity of a single neuron

an electrode used to record the electrical activity of large numbers of neurons in a particular region of the brain

a computerized method of detecting metabolic or chemical changes in particular regions of the brain

a functional imaging method; reveals the localization of radioactive tracer in a living brain
