Biomedical engineering researchers have uncovered a previously unknown source of two key brain waves crucial for deep sleep: slow waves and sleep spindles. Traditionally believed to originate from one brain circuit linking the thalamus and cortex, the team's findings suggest that the axons in memory centers of the hippocampus play a role.

Biomedical engineering researchers have uncovered a previously unknown source of two key brain waves crucial for deep sleep: slow waves and sleep spindles. Traditionally believed to originate from one brain circuit linking the thalamus and cortex, the team's findings suggest that the axons in memory centers of the hippocampus play a role.

"Our research sheds light on a previously unrecognized aspect of deep sleep brain activity," said lead author Mengke Wang, former UC Irvine undergraduate student in biomedical engineering who is now a graduate student at Johns Hopkins University .

V. Raman and his colleague K. S. Krishnan discovered that when light interacts with matter, parts of the scattered light undergo changes in energy due to interaction with molecular vibrations, resulting in what is known as Raman scattering.
