What does happiness look like in your brain?
This little video shows molecules of the protein myosin dragging a ball of endorphins along an active filament into the inner part of the brain’s parietal cortex. That produces feelings of happiness.
Someone else said it is the motor protein kinesin transporting intracellular material along a microtubule.
I don’t know what it is, but the thought of this little walk happening in my brain makes me smile.
UPDATE: The creator of the animation is John Liebler.
