Columbia researchers identify nerve cells that drive fruit fly's escape behavior

Columbia University researchers have identified the nerve cells that initiate a fly's escape response: that complex series of movements in which an animal senses, and quickly maneuvers away from, something harmful such as high heat.

BIST researchers develop new retinal prosthesis to address visual degeneration

A healthy retina contains photoreceptor cells that convert light changes into nerve impulses, which are then carried along the optic nerve to the brain, where they are decoded into images. Diseases such as retinitis pigmentosa cause the photoreceptor cells to stop functioning, while the rest of the eye remains healthy.
