microtubule

A very short animation of a kinesin motor protein walking along a microtubule inside a cell, carrying cargo.

Ron Vale of UCSF and HHMI gives an introductory lecture on kinesin, dynein and myosin motor proteins. He covers their roles in cells and how they turn ATP hydrolysis into directed motion and force.

Clip from Lex Fridman's podcast with Roger Penrose in which Penrose argues that consciousness is not a computation. He discusses Godel-style arguments and the possible role of quantum effects in microtubules.

A 2020 UC San Diego event with Roger Penrose and Stuart Hameroff presenting their Orch OR theory that consciousness arises from quantum processes in brain microtubules, followed by a conversation with Roger Bingham.

PBS Space Time examines Roger Penrose's idea that consciousness arises from quantum processes in the brain, and reviews new evidence about microtubules. It ends with an estimate of what replicating consciousness would demand.
