Posterior vitreous detachment (PVD) occurs when the vitreous—a gel-like fluid in the eye—detaches from the retina. This results in eye floaters and flashes of light that can be annoying but is usually ...

A new study suggests that never-seen-before stem cells in the human retina can restore vision in mice with a common eye disorder. But more work is needed to translate the treatment to people.

We combined optogenetic stimulation of the dorsal raphe nucleus (DRN) with wide-field calcium imaging, extracellular recordings, and iontophoresis of serotonin (5-HT) receptor antagonists in the mouse ...

Using postnatal mouse raphe neurons in culture, we first observed that in contrast to 5-HT itself, other phenotypic markers of 5-HT axon terminals such as the 5-HT reuptake transporter (SERT) show a ...
