These trailblazers strike out into various parts of the brain, laying down axons as they go.

Sometimes bigger really is better - but does the size of the brain, or brain bumps, mean what we think?
  • BrainFacts/SfN
People differ enormously as to what they consider to be stressful and how they respond to it. In general, short periods of moderate stress can actually be a good thing for the brain.

Whiskers give mice a tactile advantage. Scientists study the brains of mutant mice to learn about the development of specific brain regions, such as those involved in touch.

The human brain — a spongy, three-pound mass of tissue — is the most complex living structure in the known universe.
  • BrainFacts/SfN
The cerebrum, the largest part of the human brain, is associated with higher order functioning, including the control of voluntary behavior. Thinking, perceiving, planning, and understanding language all lie within the cerebrum’s control.

The two halves of the nervous system work together in order for your body to properly communicate its sensations and needs.
  • BrainFacts/SfN
Often considered the most important sense for humans, hearing allows us to communicate with each other by receiving sounds and interpreting speech.
  • BrainFacts/SfN
From the stands at sports events, we marvel at the actions of athletes. But in fact, each of us in our daily activities performs a host of complex, skilled movements that are just as remarkable.
  • BrainFacts/SfN
Networks of spinal neurons also participate in controlling the alternating action of the legs during normal walking, maintaining posture, and, to a large degree, in all movements.
  • 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
From remembering a friend's face to figuring out where you left your keys, the act of memory has many dimensions.
  • BrainFacts/SfN
Why do we get sleepy? There are two main determining factors: the circadian system (time of day or night) and how long we have been awake.
