Microtubules are identified as essential subcellular structures located within neurons, serving as the site for proposed quantum computations and architectural support as described in [1], [2], and [3]. The Orch-OR theory further links these two concepts by positing that consciousness arises from quantum processes occurring specifically within the microtubules found inside neurons [4], [5], and [6].

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.
claimStuart Hameroff integrated the concept of orchestrated objective reduction with biological systems by proposing that microtubules, which are large polymers essential to cellular structure and function, could provide a framework for quantum processes within neurons.
