Quantitative Electroencephalography and Behavioural Correlates of Daytime Sleepiness in Chronic Stroke
Figure 3
Topographical mapping of group differences in the EEG: level of significance for -tests between (a) left () and (b) right () side stroke compared to controls is presented. When correcting for multiple comparisons of 64 electrodes, alpha level is . This is indicated approximately by the grey line on the axes.
