Fig. (2) Features and dynamics of neuronal assemblies (indexed by EEG segment attributes) as a function of clinical outcome 6 years post-injury: Linear regression analysis. Data are averaged across all EEG channels and all 1-minute EEGs within each state. The values of attributes of neuronal assemblies indicated by the Y-axis: size of neuronal assemblies-amplitude within each segment (microvolt); life-span of neuronal assemblies-length of segments (milliseconds); instability of neuronal assemblies-coefficient of amplitude variability within segments (%). Lines in the graphs represent the linear regression equation and R2. Abbreviations: Alpha: EEG rhythm 7-13 Hz; Beta-1: EEG rhythm 15-25 Hz; Beta-2: EEG rhythm 25-30 Hz. EEG: electroencephalogram; VS-Pers: patient continues to be in persistent vegetative state 6 years post-injury; VS-MCS: patient continues to be in minimally conscious state 6 years post-injury; VS-E-MCS: patient emerges from minimally conscious state 6 years post-injury.
