Daily brief research updates from the cognitive sciences
Our brain are blobs of real organic material, but we also know real material at the very small level enters into the quantum world where very strange rules apply to baffle all but the smartest scientists, and even some of the smartest scientists (such as Einstein).
There are also multiple open questions in science such as the experience of consciousness and how our brains can still outperform supercomputers in certain circumstances and conditions. That our brain uses quantum processes could explain this and has been proposed by many people before – but this is all speculation and theoretical musings. However, now we have the first glimpse of proof that our brains do indeed engage in quantum processes.
Christian Matthias Kerskens and David López Pérez of Trinity College Dublin conducted a clever experiment to try to measure what can’t be measured. I am at the limits of my knowledge, and it gets complex but let me have a go at explaining.
In trying to measure the quantum we are trying to measure the unmeasurable but there are ways to do this, for example entanglement is when particles become connected and behave in the same why despite no obvious connection and being distant in space and time. What Einstein called “spooky action at a distance”.
What Kerskens and Lopeze Perez did was to measure proton spins in brain water – a natural fluid that builds up in our brain. Using a special MRI technique they were then able to measure proton spins but also to look for entangled spins. They were then able to identify EEG signals in the spins. But this would normally not be able to be observed under these conditions unless, that is, there was entanglement.
This suggests that these protons are entangled and therefore showing EEG signals despite not receiving this input directly. This is one of the first cases of direct evidence for quantum processes in the brain and this would also explain why the brain can perform some of the things it can despite its limited size. It could also help explain some aspects of consciousness – but the topic of consciousness is hotly and fiercely debated so let’s not go there for now.
Further research is necessary, of course, but it is a first promising step to getting more concrete grip on our quantum brain.
