Table 1. Average event-related changes in concentrations of HbO₂, HHb and ox-CCO and calculated p-value from paired-sample t-tests (performed between the initial moment of each event and the maximum induced changes); arrows show the direction of the average changes that were statistically significant and the changes that were not statistically significant are shown by ≈.
