For all its flaws, Harry's Electrochemistry does want him to do his actual job for that sweet, sweet serotonin. Betta's Sensation is similar, and doesn't really want her getting caught up in depressive spirals about the bleak nature of existence and the uncaring false gods beneath the sea when there's so many better feelings in life. It's not just about drugs and sex - though yes. It does want those.Having the more physical side of our knowledge take part makes sense considering Tides/Shivers is more or less just that already, but Sensation?
Not if I have anything to say about it!
