Researchers identify neurons that control brain's body clock

Neurons in the brain that produce the pleasure-signaling neurotransmitter dopamine also directly control the brain's circadian center, or "body clock" - the area that regulates eating cycles, metabolism and waking/resting ...

How to generate new neurons in the brain

Some areas of the adult brain contain quiescent, or dormant, neural stem cells that can potentially be reactivated to form new neurons. However, the transition from quiescence to proliferation is still poorly understood. ...

Astrocytes found to keep time for brain, behavior

Until recently, work on biological clocks that dictate daily fluctuations in most body functions, including core body temperature and alertness, focused on neurons, those electrically excitable cells that are the divas of ...

Brain wiring quiets the voice inside your head

During a normal conversation, your brain is constantly adjusting the volume to soften the sound of your own voice and boost the voices of others in the room.

Optical illusions explained in a fly's eyes

Why people perceive motion in some static images has mystified not only those who view these optical illusions but neuroscientists who have tried to explain the phenomenon. Now Yale neuroscientists have found some answers ...

Scientists discover what controls waking up and going to sleep

Fifteen years ago, an odd mutant fruit fly caught the attention and curiosity of Dr. Ravi Allada, a circadian rhythms expert at Northwestern University, leading the neuroscientist to recently discover how an animal's biological ...

Pupil dilation: A window to perception

The eyes are often referred to as the "windows to the soul." In fact, there is a grain of neurobiological truth to this. An international research team from the Universities of Göttingen and Tübingen, Germany, and Baylor ...
