GNU Affero General Public License v3 Yes University of Ottawa NITRC DetectSpindles Method for detecting sleep spindles using EEGlab functions and datasets. A spindle detection method was developed that: (1) extracts the signal of interest (i.e., spindle-related phasic changes in sigma) relative to ongoing “background” sigma activity using complex demodulation, (2) accounts for variations of spindle characteristics across the night, scalp derivations and between individuals, and (3) employs a minimum number of sometimes arbitrary, user-defined parameters.
