Mainstream views assume consciousness emerges from complex synaptic computation among brain neurons, each acting as a fundamental information unit. However such views fail to 1) generate testable predictions, 2) provide supportive evidence, or 3) distinguish conscious from non-conscious processes. Moreover, single cell organisms perform cognitive activities without synaptic connections, utilizing cytoskeletal microtubules which regulate neuronal synapses, and organize neuronal activities.

Cylindrical polymers of the protein tubulin (the brain’s most prevalent protein), microtubules are proposed to process information, encode memory, and serve as quantum computers underlying consciousness in the Penrose-Hameroff model of ‘orchestrated objective reduction (‘Orch OR’).

The idea of quantum computing in the ‘warm, wet and noisy’ brain has been viewed skeptically, but evidence in recent years supports warm, biological quantum coherence in photosynthesis, DNA and microtubules. This workshop will review and update the relevant biology, biophysics and pharmacology of microtubules.

Speakers will cover the following topics:
