Discovery of Quantum Vibrations Inside Brain Neurons Supports Controversial Theory of Consciousness

Is your brain connected to the universe at a quantum level?

The recent discovery of quantum vibrations inside neurons in the brain supports a controversial theory of consciousness.

If correct, it might lead to new treatments for many different conditions, it is claimed in a new review of the evidence by Hameroff and Penrose (2013).

The theory–which implies the brain is connected to the universe at a quantum level–was first proposed in the 1990s, but it suffered extensive criticism.

One major point against it was that the brain was thought to be too “warm, wet and noisy” for coherent quantum processes.

Recent evidence, though, from researchers led by Anirban Bandyopadhyay has found the proposed quantum vibrations inside microtubules within brain neurons.

These microtubules are components of cell scaffolding–they help provide our cells with their structure–that are around 25µm in length.

Other research has also found evidence of quantum coherence in living cells. It has been found in our sense of smell, in the parts of bird’s brains responsible for navigation and in plant photosynthesis.

Hameroff and Penrose explain that their theory suggests…

“…consciousness derives from quantum vibrations in microtubules, protein polymers inside brain neurons, which both govern neuronal and synaptic function, and connect brain processes to self-organizing processes in the fine scale, ‘proto-conscious’ quantum structure of reality.”

They claim that their theory is…

“…the most rigorous, comprehensive and successfully-tested theory of consciousness ever put forth. From a practical standpoint, treating brain microtubule vibrations could benefit a host of mental, neurological, and cognitive conditions.”

They also think that the electrical ‘brain waves’ which can be detected by an EEG machine could be a result of these deeper level microtubule vibrations.

The restatement of the theory has produced a flurry of criticism in the journal where it was published, Physics of Life Reviews, but the authors maintain that their theory suggests…

“…conscious experience is intrinsically connected to the fine-scale structure of space–time geometry, and that consciousness could be deeply related to the operation of the laws of the universe.”
