Part 2/9:
Microtubules are essential components within cells, playing a critical role in various cellular functions, including signal transport in the brain. They are polymers composed of tubulin proteins that combine to form tube-like structures. Penrose suggests that the collapse of the wave function in quantum mechanics—a key element of quantum theory—could explain an uncomputable aspect of consciousness. When quantum possibilities collapse into actualities, it may give rise to conscious thought.
