Several electrical and imaging techniques are now used to compare behavior to the functioning of specific areas of the brain. Describe four of these techniques and suggest the types of research questions they may answer.

Question

The Answer is The answer should provide the following information: (1) Electroencephalogram: time-linked patterns of electrical patterns across the active brain, useful in studies of sleeping and waking; (2) Functional magnetic resonance imaging: pictures of areas of high blood oxygen flow; captures differences in brain use during tasks. For example, what areas on the brain are active when you tell a lie? (3) Positron emission tomography: generates a picture of brain function by measuring the differential absorption of a harmless radioactive material in brain regions. The research questions must involve questions regarding chronic brain functioning Transcranial magnetic stimulation: delivers a magnetic pulse that passes through the skull that can temporarily deactivate neurons in the cerebral cortex. The ability to switch on and off cortical regions allows for the determination of cause and effect between brain function and behavior.
