It doesn’t take brainpower to react to sudden danger; just a bit of spine.

Scientists are rethinking the role of nerve endings once thought to be involved in providing spatial information to the brain.

Think fast! Figure out your brain’s reaction time with this activity.
  • Scientific American
Students are introduced to brain structure, neurotransmitters, hormones, and neural networks in this nine part lesson.
  • Baylor College of Medicine
Neurons in the brain and spinal cord cooperate to control complex movements, such as walking or swimming. Studying simple animals helps us understand how motion develops.
  • BrainFacts/SfN
Neurons communicate with muscles in special kinds of connections called neuromuscular junctions. These exchanges help muscles to flex.
  • BrainFacts/SfN
The giant sea slug Apylsia has a simple nervous system that makes them a useful model for neuroscience research. They also have rows of tiny sharp teeth, which cover a tongue-like structure.
  • BrainFacts/SfN
Tossing and turning generally occurs during very brief arousals from sleep during the night.
  • 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
Perhaps the simplest and most fundamental movements are reflexes. These are relatively fixed, automatic muscle responses to particular stimuli, such as the slight extension of the leg when a physician taps the knee with a small rubber hammer.

This interactive web resource has articles with photos and demonstrations about how the brain processes information from our bodies, generates thoughts and emotions, stores and recalls memories, and controls movement. Also, watch a video about how scientists store and use donated brain tissue.
  • National Geographic
Beginning in the 1940s, Canadian brain surgeon Wilder Penfield mapped the brain's motor cortex -- the area that controls the movement of your body's muscles. Now you can relive his exploration of the brain.
