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.

Neurons communicate with muscles in special kinds of connections called neuromuscular junctions. These exchanges help muscles to flex.

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.

Dragonflies hover smoothly in part thanks to information collected by their eyes. Knowing these insects' retinal circuitry helps scientists understand how neurons process spatial data.

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.

Computer models of proteins involved in metabolism, the chemical reactions that sustain life, help researchers understand how disease affects their function.
  • BrainFacts/SfN
Star-shaped glial cells, sensibly named astrocytes, are found throughout the central nervous system. Scientists can use luminescence to make the cells actually glow as they communicate.

How does the brain track smells? Scientists use the olfactory system in insects to study how the brain responds to and processes different odors.
Neurons in the eye turn light into electrical signals. How and where signals travel between these cells is thought to affect vision.
Synesthesia is a condition in which stimulation of one sense automatically evokes a perception in an unstimulated sense.

The human brain — a spongy, three-pound mass of tissue — is the most complex living structure in the known universe.
