New research shows a single neuron in fruit flies can trigger two distinct behaviors in response to the same smell.
In recent years, advances in molecular genetics have impacted the understanding and the classification of hereditary retinal and optic nerve disease perhaps more than any other group of eye diseases.
Optic nerve The optic nerve sends messages from the eyes to the brain. When light enters the eye, it hits the retina, which contains rods and cones.
Human eyes contain light-sensitive cells called photoreceptors, which are divided into two types: rod cells and cone cells. Cone cells detect red, green, and blue in bright light, and the brain ...
Medically reviewed by Andrew Greenberg, MD Photophobia is an intolerance or sensitivity to light. It is linked to various eye ...
Yu reviewed the benefits and limitations of various electrophysiologic technologies in a diverse group of inflammatory conditions affecting the retina and optic nerve.
The retina contains millions of photoreceptive cells called cones, rods, and blood vessels that nourish these cells. The optic nerve carries visual information from the retina to the brain. Glaucoma ...
Find out what you need to know about blind spots (scotomas). Learn about their causes, the treatment required, and how they affect your vision.
In order to see, however, you also need your optic nerves to transmit nerve impulse to your brain, which then adjusts and interprets the images of the world surrounding you.
