Eeg electrode array and method of use

Provided herein are methods for EEG monitoring of a patient, which includes: positioning an array comprising a plurality of EEG electrodes on the patient's head; recording, during a first time period, a first data set of EEG signals from a first set of spatial scalp locations; manipulating the array to record, during a second time period, a second data set of EEG signals from a second set of spatial locations including at least some spatial scalp locations that are different from the first set of spatial scalp locations; integrating the first and second data sets, thereby generating a combined data set with a higher spatial density; and processing the combined data set to determine EEG events.
