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.
  • 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.

Research into the razor-sharp hearing of barn owls reveals how we create mental maps of space and may lead to hearing loss solutions.
  • BrainFacts/SfN
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.

Once the neurons reach their final location, they must make the proper connections so that a particular function, such as vision or hearing, can emerge.
  • 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.

Scientist targeted by animal rights activists asks about the ethics of inaction.
  • BrainFacts/SfN
This Web resource highlights the valuable role that animals play in biomedical research. The anatomy of the reward pathways in the human brain and the rat brain are compared to emphasize their similarities.
