Immune cells in the retina can spontaneously regenerate

Immune cells called microglia can completely repopulate themselves in the retina after being nearly eliminated, according to a new study in mice from scientists at the National Eye Institute (NEI). The cells also re-establish ...

Unifying the theories of neural information encoding

Digital video cameras have the capability to record in incredible detail, but saving all that data would take up a huge amount of space. Researchers seek new methods to compress video—that is, remove information—in such ...

Untangling the complex puzzle of optic nerve regeneration

The optic nerve is vital for vision—damage to this critical structure can lead to severe and irreversible loss of vision. Fengfeng Bei, PhD, a principal investigator in the Department of Neurosurgery at Brigham and Women's ...

New insight into eye diseases

Many diseases that lead to blindness, such as glaucoma and macular degeneration, are caused by the death of certain cells in the human retina that lack the ability to regenerate. But in species such as zebrafish these cells, ...

From retina to cortex: Unexpected division of labor

Neurons in our brain do a remarkable job of translating sensory information into reliable representations of our world that are critical to effectively guide our behavior. The parts of the brain that are responsible for ...
