Table 1.
Similarities and differences between oscillations of the EEG power in the sigma frequency band (sigma-ISO, infra-slow oscillation) and the Cyclic Alternating Pattern (CAP).
| Sigma-ISO | CAP | ||
|---|---|---|---|

| REM | NO | NO | |
| Mapping | Parietal | Fronto-mesial and/or parieto-occipital | ? |
| Spindles Density | High correlation | Low | High |
| Sensory Threshold | High | Low | High |
| Hippocampal Ripples | High | ? | ? |
| Cognitive Process | High Correlation | High Correlation | |
