So, I was an introvert now. Huh. I started researching it. Turns out it’s all about blood flow in our brains. Extrovert brain blood flow is directed to the regions of the brain concerned with interpreting sensory data – making sense of the outside world. Whereas introvert brain blood flow is more pronounced to the frontal lobe, which deals with the internal processes of decision-making, memory, solving problems – our inner landscape.
