Modulation of Functional EEG Networks by the NMDA Antagonist Nitrous Oxide

Figure 5

Dependence, for the 60% peak gas group, of GE-based functional connectivity () defined relative to the median during rest on N2O gas concentration for full brain (top row), frontal (middle row) and parietal (bottom row) networks, obtained either with common-reference (left column) or Laplacian re-referencing (right column).

Box-whisker details: Red horizontal lines indicate bin distribution median; Upper and lower blue box edges correspond to 75th and 25th percentiles, respectively; Black dashed whiskers span 99.3% of the distribution assuming a normal distribution; The red crosses indicate outliers. The bins labelled above by and indicate the mean is statistically significant from rest for significance levels of and corrected for multiple comparisons, respectively.
