The cyclic alternating pattern (abbreviated CAP) occurs in sleep. It is characterized by periodic abnormal [[electrocortical activity that recurs with a frequency of up to one minute, and can be detected using electroencephalography (EEG).[1] It is considered "the EEG marker of unstable sleep".[2]

CAP does not occur in REM.[1]
