This is when we are alert at our wake fullness. Stage one sleep RRG is low voltage but high frequency signal. As the stages progress into stage 2 there’s a gradual increase in EEG voltage and decrease in EEG frequency. Stage 2 has a higher amplitude and lower frequency and also has two wave forms‚ k complexes and sleep spindles
