Figure 2

A non-specific pupil dilation response to sounds was observed both in the MCS and in the VS/UWS patients and did not differ between the two groups. Grand averages of pupil diameter (in pixels) are plotted over time (in seconds) in MCS (n = 14) and VS/UWS patients (n = 10). Grey dotted lines index first sound onset and fifth sound offset respectively. Temporal windows in which the pupil dilatation is significant from baseline are marked in with horizontal blue (MCS) and orange (VS/UWS) lines.
