PSYC3338 Study Guide - Midterm Guide: Richard Caton, Cerebral Cortex, Sleep Deprivation
Document Summary
Seizure = sudden brief period of abnormal electrical discharge in the brain - altered consciousness, involuntary movements, convulsions. Could have a seizure once (fever or dehydration not epilepsy) Epilepsy = spontaneously recurring seizures, can be 100 or more/day. Injury, trauma, tumor (1st sign would be a seizure), infection (meningitis and encephalitis), genetic conditions, structural abnormalities in blood vessels, fever, sleep deprivation, diabetes, drug withdrawal and adverse effects of drugs. = measures rhythmic electrical activity in a large population of neurons in the cerebral cortex. Measures the electrons in a person"s skull - look at brain waves. Differ depending on if you are awake or asleep. Richard caton first to record a human eeg in 1929. Berger saw that eegs during sleep are different than while awake. Eegs are used to help diagnose neurological conditions epilepsy and sleep disorders. Eeg recordings (can do it through hair)
