Whether cancerous or not, brain tumors are serious because they can interfere with normal brain function.

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.

Studies of the body’s own pain-control system demonstrated the existence of naturally occurring opioids — the endorphins.

Medical science offers us a number of different ways to dull or treat pain.

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.

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
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.

In response to signals from a brain region called the hypothalamus, the adrenal glands secrete glucocorticoids, hormones that produce an array of effects in response to stress.
  • BrainFacts/SfN
A stressful situation activates three major communication systems in the brain, all of which regulate bodily functions.
