Dragonflies hover smoothly in part thanks to information collected by their eyes. Knowing these insects' retinal circuitry helps scientists understand how neurons process spatial data.

The brain receives information about the outside world via the senses. But how much of this information do we actually notice?
  • BrainFacts/SfN
Neurons in the eye turn light into electrical signals. How and where signals travel between these cells is thought to affect vision.
Synesthesia is a condition in which stimulation of one sense automatically evokes a perception in an unstimulated sense.
  • BrainFacts/SfN
To be able to see anything, eyes first need to process light. Vision begins with light passing through the cornea.
  • BrainFacts/SfN
The moment light meets the retina, the process of sight begins. About 60 years ago, scientists discovered that each vision cell’s receptive field is activated when light hits a tiny region in the center of the field and inhibited when light hits the area surrounding the center.

During this lab activity, students will explore two types of sensory processes. First, they will investigate how one identifies different flavors. Then, they will explore the ways the brain interprets the visual images that reach the eye.
  • University of Pennsylvania
An interactive website about the eye. Learn about the parts of the eye and eye safety, and try out some optical illusions.
  • National Eye Institute
This site provides experiments on hearing, smell, taste, touch, and vision designed for students in primary and secondary school classrooms.
  • Center for Behavioral Neuroscience
Every morning we wake up and regain consciousness, but what exactly is it that we regain? Neuroscientist Antonio Damasio uses this question to give us a glimpse into how our brains create our sense of self.
