Sing us a sula, O, susuria!
Here’s a paper from 1985 titled, EEG during masturbation and ejaculation. In this study, they had three men masturbate and ejaculate while undergoing EEG (ElectroEncephaloGraphy). (…)
The authors didn’t really do any strong quantitative analyses of their EEG. More just qualitative observations. The methods in this paper are a great read, though. They recorded 14 channel scalp EEG. In addition, they also recorded:
“Anal Contractions” with a “pressure-sensitive anal probe”.
“Penile Tumescence” with a “mercury strain gauge”. Unfortunately, “[t]he masturbatory movements interfered with the recording”.
“Wrist Accelerometer” that was “taped to the dorsum of the hand (right) used in masturbation”.
And the procedures really give you a sense of the beauty of the entire setup: “Subjects were instructed to avoid unnecessary movements, and their compliance was verified by video monitoring of head and torso throughout the session. (…) The average length of masturbation to the first anal contraction was 402 seconds.”
