Document Summary
Learning objectives: generate some questions a clinical neurophysiologist might ask about a patient. 2. generate some questions an experimental neurophysiologist might ask about humans. 3. understand the differences between neurophysiological human recording techniques. Intracranial electroencephalography (ieeg: best way to measure electrical activity of the brain. Median nerve in arm) and observe the electrical response in the brain: or can be done by stimulating electrodes and observe the resulting. Scalp eeg behaviour: not as good as ieeg, but much less invasive, used for clinical monitoring, diagnosis, or experimentally in research. In research -> study event related potentials (erps) or neural oscillations (rhythms) in brain function/dysfunction: monitoring, used to look for abnormal activity (seizures, brain death, etc. ) in intensive care units, during surgery, etc. In people who are at increased risk of abnormal brain activity. Primary visual cortex activity: p300 = higher cognition, inhibition, executive function, ex. Alcoholics and psychopaths often have low p300 due to low inhibition: n400 = language comprehension, semantics.
