Medical science offers us a number of different ways to dull or treat pain.
  • BrainFacts/SfN
Processing information from the sensory systems is one of many functions of the brain. Such information is often the first step in other brain activities, including learning and retaining knowledge.

Touch is the sense by which we determine the characteristics of objects: size, shape, and texture.

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.

Although most of us don’t think of it in this way, the related senses of taste and smell help us interpret the chemical world.

Cells within the nervous system, called neurons, communicate with each other in unique ways. The neuron is the basic working unit of the brain.
