First paragraph of the "4. Discussion and Conclusion" section

> We speculate that the participant’s fair skin and lack of hair were significant factors that reduced the attenuation of light to feasibly detect a signal. In addition to the participant wherein a signal was observed, the experiment also included trials on seven other subjects. The details of the subject pool are as follows: two females and six males; 25 to 35 years old; 14.5 to 15.5 cm head diameter; Fitzpatrick skin types: 3 type I, 4 type II, and 1 type V; hair types: 1 bald, 4 short and light-colored, and three dense and dark-colored. We did not observe any significant time-correlated signals above background noise for the seven other subjects.
