Some specifics to look for and keep in mind based on this video and research:
- The brain will turn different colors based on the blood oxygen levels. The lighter colors indicate more oxygen which signals that part of the brain is most active at the moment.
- Activity was found in more than 80 regions of the brain.
- Oxytocin and dopamine flood the brain producing a euphoric feeling.
- The same part of the brain that is responsible for controlling pain also appears to active during orgasm, which seems to explain those "O-faces".
- More research is sure to be done!
