Impact of Colored Light on Cardiorespiratory Coordination

Figure 3

Analysis of centering of cardiorespiratory coordination towards 4 : 1 during exposure to red and blue color lights. (a), (c) During red light the significant negative correlation coefficient for HRR and PCR indicates a centering towards 4 : 1. (b), (d) During blue light a centring does not occur; that is, the correlation is not significant. Note that in diagram (d) the high correlation is spuriously caused by the outlier in the lower right part of the diagram. Dashed lines indicate average (and ) and average (and ), respectively.
