Basic neuroscience research in animal models is essential to understanding brain function and the thousands of brain diseases and disorders that affect both humans and animals. Treatments for stroke, depression, and drug addiction are just a few examples of developments made by this research. Learn more.

Human brain cell transplantation makes mice smart. The transplanted cells are not neurons and the cells communicate without using electricity.

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.

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

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.
The discovery of a protein that gives jellyfish their colorful glow revolutionized scientists' view of the nervous system, allowing them to add color to what had only been seen in black and white.
