| Question | Answer |
| Alpha frequency | 8-12 Hz |
| Beta frequency | > 12 Hz |
| Theta frequency | 4 to 7 Hz |
| Delta frequency | < 4 Hz |
| Alpha Rhythm | 8-12 Hz, 20-70 microvolts, occipital, blocks on eye opening |
| Stage I non-REM sleep | Alpha drop out, diffuse slowing, vertex waves |
| Stage II non-REM sleep | Vertex waves, sleep spindles |
| Slow wave sleep | > 25% delta, > 75 microvolts, sleep spindles |
| REM sleep | low voltage, mixed frequencies, usually alpha, rapid eye movements, no myogenic artifacts |
| Electroencephalography | graphic representation of the difference in voltage between two different cerebral locations in time. |
| Volume conduction | the process of current flow through the tissues between the electrical generator and the recording electrode |
| EEG source | Both excitatory postsynaptic potentials (EPSPs) and inhibitory postsynaptic potentials (IPSPs) contribute to the synaptic activity recorded as EEG |
