claimThe Orch OR theory posits that information processing in the brain occurs at the level of microtubules, which shape neurons and provide their unique architecture, though this theory conflicts with established principles of neuroscience.

claimRoger Penrose and Stuart Hameroff have argued that microtubuli are the potential location for quantum state reductions in the brain.
Quantum Approaches to Consciousness plato.stanford.edu Stanford Encyclopedia of Philosophy 1 fact
claimThe focus on microtubules in the Penrose-Hameroff hypothesis is motivated by the need for protected locations where quantum states can persist long enough to undergo gravitational reduction before interacting with the warm, wet environment of the brain.
