The choice of 810 nm is also supported by photobiology: this wavelength aligns well with the absorption spectrum of cytochrome c oxidase (the mitochondrial “light receptor”) and has been widely used ...

A study on the effects of commonly used anaesthetic and sedative drugs on cerebrospinal fluid flow and volume has uncovered findings regarding their impact on the brain's vital glymphatic system.

Researchers report that the flow of cerebrospinal fluid in the brain is linked to waking brain activity. The study demonstrates that manipulating blood flow in the brain with visual stimulation ...

A popular hypothesis for how the brain clears molecular waste, which may help explain why sleep feels refreshing, is a subject of debate. Encased in the skull, perched atop the spine, the brain has a ...

Fluid buildup can signal a worsening health condition or lead a patient to multiple trips to the hospital. For patients with hydrocephalus, an accumulation of cerebrospinal fluid (CSF) in the brain, ...

Waves of cerebrospinal fluid which normally wash over brains during sleep can be made to pulse in the brains of people who are wide awake, a new study finds. The clear fluid may flush out harmful ...

The rapid influx of cerebral spinal fluid (CSF) and protein solutes released during cortical spreading depression (CSD) in the brain activates neurons to trigger aural migraine headaches, according to ...

Ceribell received breakthrough device designation for its LVO stroke detection monitor, and Naox Technologies secured 510(k) clearance for its in-ear EEG device.
