| 4921 | Quantum states in microtubules could bind brain activity to produce consciousness |
| Full Idea: I propose that microtubules in nerve cells could give rise to a stable quantum state that would bind the activity of brain cells throughout the cerebrum and in doing so give rise to consciousness. | |||
| From: Roger Penrose (Could a computer ever understand? [1998], p.329) | |||
| A reaction: This seems to offer a physical theory to account for the 'unity' of the mind (which so impressed Descartes), but I don't quite see why being aware of things would ensue from some 'quantum binding'. I daresay 'quantum binding' occurs in the Sun. |
