Not really. Polysomnography tracks a wide range of variables, including multi-lead EEG & EKG, various EMG sites (tibialis, extraocular, masseter etc.), chest and abdominal respiratory effort via bands, pulse oximetry, nasal airflow, throat microphone, position sensors, and so on. Yes, I suppose in a way those measure "electrical current activity" since all the sensors are ultimately electronic. However, most of what's being monitored has little to do with "electrical current activity."
