For observations based on sensory data, the human brain must constantly verify which "version" of reality underlies the perception. The answer is gleaned from probability distributions that are stored ...

Vision is a highly complex process, and requires the construction of a correspondingly complicated functional network made up of diverse nerve-cell types in the developing retina. In mammals, these ...

Optic nerve hypoplasia (ONH), which is defined as a congenital deficiency of retinal ganglion cells, may also involve more distal layers of the retina. We investigated electrophysiological function of ...

The trigeminal nerve is a cranial nerve. It arises from the brainstem, and its branches cover your face and head. The trigeminal nerve is a paired nerve — you have one on each side. Its chief function ...

Obesity does not just enlarge fat stores, it appears to rework the body’s wiring and immune landscape in ways scientists have ...
