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.

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.

From remembering a friend's face to figuring out where you left your keys, the act of memory has many dimensions.
  • BrainFacts/SfN
A major breakthrough in understanding how the brain accomplishes learning and memory began with the study of a person known by his initials, H.M.
  • BrainFacts/SfN
How exactly are memories stored in brain cells? After years of study, much evidence supports the idea that memory involves a persistent change in synapses, the connections between neurons.
  • BrainFacts/SfN
An estimated 8 to 10 percent of children in the U.S. have some form of learning disability involving difficulties in the acquisition and use of listening, speaking, reading, writing, reasoning, or mathematical abilities. These problems often occur in people with normal or even high intelligence.
