Scientists are exploring how brain activity generates our thoughts and decisions. To do this, they borrow ideas from quantum physics, showing that neural networks can create 'entangled' states, akin to the link between particles. Imagine: two people thinking the exact same thing at the same time, without any communication—something similar may happen in the brain. What if our thoughts can actually become 'entangled'?
The brain generates quantum-like states without a single quantum particle. As electrical waves of nerve cells synchronize, they give rise to a mathematical analog of entanglement. Like an orchestra where cellos and flutes, playing separately, suddenly start carrying a single melody, distant brain regions link into a unified network—a veritable galaxy of thought.
This model can be tested: brain spectroscopy (EEG) already picks up traces of quantum-like states. This moves theories of consciousness from philosophical debate into experimental science.
Entropy—a measure of uncertainty—bridges physics and psychology, explaining how sudden insights are born.
🎯 EEG records brain rhythms reminiscent of the twinkling of galaxies. Astrophysicists have long used spectroscopy; now neuroscientists will arm themselves with it to see the quantum effects of thought.
