12. Diagrammatic comparison of the electrical responses of the axon and the dendrites of a large cortical neuron. 2. Mechanism of EEG Current flow to and from active synaptic knobs on the dendrites produces wave activity, while AP are transmitted along the axon.

14. 3. EEG Records During Epileptic Seizure Epilepsy is characterized by uncontrolled excessive activity of either a part or all of the central nervous system. Grand mal epilepsy: characterized by extreme neuronal discharges in all areas of the brain, last from a few seconds to 3 to 4 minutes. Petit mal epilepsy: Characterized by 3 to 30 seconds of unconsciousness or diminished consciousness during which the person has several twitch-like contractions of the muscle.
23. Pontine-geniculate-occipital (PGO) wave – A synchronized burst of electrical activity that originates in the pons and like a wave it activates the lateral geniculate nucleus (first relay of visual information) and then the occipital lobe, specifically in the visual cortex (which receives and puts together the visual information that comes from the lat. geniculate nucleus). PGO waves appear seconds before and during REM sleep.
Dualism-mind is separate from the body Descartes believed that the pineal body directed fluid from the ventricles into the holow fibers we call nerves-this induced muscle action. The pineal gland is where the soul controls the physical body Monism: the belief that the mind is the working of the body (no need for a separate soul. Determinism-the notion that mental states are produced by physical mechanisms. Reductionists-we break complex phenomena into less complicated sytems.
