I’ve been meaning to share this amazing illustrator (Tom Geisler) who has drawn out the internal organs as they respond to emotion. Very cool!
No word on whether you can go backwards, and stimulate the organs (aka do yoga) to generate the emotion.
I tried medical illustration once and it was a bust, it is so hard to visualize such detailed configurations of three-dimensional objects that you’ve never seen. Quite impressed with Tom’s work.
