Scientists have detected light signals that can penetrate the human brain, potentially giving birth to a new type of deep brain imaging device.

A research team from the University of Glasgow in the UK has successfully detected light signals passing through the intact skull of adult humans for the first time. This research, published in the latest issue of the journal "Neurophotonics," breaks through the limitations of existing technology for detecting depth, and may lead to the development of new optical devices capable of detecting deeper brain tissue.
