Kyokushin karate kata (KKK) practice, but not Reiki, increased delta, alpha, and theta brainwave power in the sender, especially in temporal and parietal areas, while decreasing beta power in frontal regions. Remote KKK influence increased synaptic efficacy in rat hippocampal slices by 7.5% on average, whereas Reiki showed no effect. Both KKK and Christian prayer increased light activity of distilled water, but only when the sender's delta brainwave power increased and EEG entropy decreased. Strong correlations were found between the sender's brain and energy parameters during KKK and changes in the rat's hippocampal synaptic efficacy. The findings suggest a dual biophotonic and negentropic mechanism underlying KKK's effects.
