Fig 4 Plots representing individual (thin lines) and average (thick lines) BIS values [(BIS value collected over the left hemisphere+BIS value collected over the right hemisphere)/2] of patients recorded around the time of LOC or ROC for control and tumour patients. Time 0 is the moment of transition of consciousness. LOC1, the first moment of loss of consciousness. LOC2, the second moment loss of consciousness. ROC, the moment of return of consciousness.
