The Science

Electroencephalography

[EEG] is a method used to measure the brain surface's macroscopic electrical activity translated from a multitude of scalp electrode recordings. These recordings indicate a neuronal population's activity. Medical diagnoses, such as seizure disorders or brain  injury, are determined from pathognomonic patterns in EEG waves over time. No individual signal is enough for clinical significance on its own. 

This painting presents a sample EEG of an adult person in a transitional sleep state, exemplified by the lower-frequency "theta rhythms" that emerge from the background activity - but with the recorded lines reflected through etchings into wet paint.
