The discovery of new types of cells in the brain of developing flies clarifies how the insects develop sight.

The molecule responsible for suppressing pain from heat in adult flies has the opposite role in fly larvae, research finds.

Scientists have completed the first ever map of an insect brain. "Everything has been working up to this," says Joshua T. Vogelstein.

Researchers have taken a step toward understanding how human thoughts and dreams emerge from electrical pulses in the brain's trillions of synapses.

Neurons adapt to help fruit flies stay awake in dangerous situations, a finding that could lead to new ways to treat insomnia in people.

We tend to eat, drink, and move less when we feel sick. A new study in mice uncovers brain cells that control these "sickness behaviors."

A tiny EEG cap, created to measure activity in a brain model the size of a pen dot, could lead to better understanding of neural disorders.

Wireless technology that remotely activates brain circuits in flies in less than a second could one day activate circuits in humans without needing surgery.

A new explanation for some forms of epilepsy with unknown causes could also have implications for other neuromuscular diseases such as ALS.

Research with monkeys shows that when eyes meet, neurons fire in multiple parts of the brain. It gets at how we figure out the meaning of a "social gaze."
