Scientists Investigate Whether Neurons Can Transmit Light, Opening New Frontiers in Brain Research
In a discovery that could redefine our understanding of the human brain, scientists are investigating a mind-bending question: can neurons, long known as the brain’s electrical messengers, also transmit light? This remarkable hypothesis—now being tested by interdisciplinary teams blending neuroscience with cutting-edge optics—could revolutionize both scientific knowledge and medical technology, including brain-computer interfaces and diagnostics for neurological diseases (SciTechDaily).
For Thai readers, the implications are far-reaching. The brain has traditionally been thought of as a network of cells communicating via electrochemical signals, with electricity and chemicals passing information rapidly between neurons. Now, research teams such as those at the University of Rochester are asking if neurons’ long, thin axons could carry light particles (photons) in a way that’s similar to fiber-optic cables used in internet communications (University of Rochester News Center). If proven true, this would mean the brain may have an entirely new layer—an optical internet—hidden within its already intricate wiring.
