The jury is out on this one because there is a lot of new information coming through, and nobody is quite sure how we sense those extra-sensory perceptions. It was thought that our sense of smell was 'mechanical' but the recent understanding is that it's quantum mechanics. We have quantum-capable areas of the brain that seem as though they were specifically designed to sense the quantum, so it's possible that ESP is related to quantum mechanics. Those parts are shielded from the rest of the electrical activity. Whatever we perceive though is still 'filtered' by the brain/mind anyway so.....
