Unda cerebri
Unda cerebri est industria electrica creata ab cerebro. Hae undae nimis humiles magnitudines sunt ordinis microvolts (in hominibus) sinusoidis nec semper constae. Haec unda potest esse detecta ab instrumento electroencephalographo et enumeratur infra:
- Unda delta (1 a 3 Hz)
- Unda theta (3,1 a 7,9 Hz)
- Unda alpha o rhythmus mu (8 a 13 Hz)
- Unda beta (14 a 29 Hz)
- Unda gamma (30 a 100 Hz)
| Frequentia | Nomen | EEG | Significatio |
|---|---|---|---|
| > 40 Hz | gamma |  |
|
| 13–39 Hz | beta |  |
interdum medicamenta ut grex benzodiazepinorum rhythmus beta generet |
| 7–13 Hz | alpha[1] |  |
rhythmus normalis, in senectute tardius (saepe 7.5 - 9 Hz) |
| 4 – 7 Hz | theta |  |
Generator: hippocampus? |
| 0.5–4 Hz | delta |  |
