Study reveals biology of leptin, the hunger hormone

In a new study, Yale researchers offer insight into leptin, a hormone that plays a key role in appetite, overeating, and obesity. Their findings advance knowledge about leptin and weight gain, and also suggest a potential ...

Connecting neurons in the brain

The brain consists of a large collection of interconnected neurons. How complex patterns of neuronal cells grow into functioning circuits during development has fascinated researchers for decades. A team of scientists at ...

Growth hormone acts to prevent weight loss

Researchers at the University of São Paulo (USP) in Brazil have discovered that growth hormone (GH), which stimulates skeletal maturation and linear bone growth, as well as helping maintain tissue and organs throughout life, ...

Mapping the neural circuit of innate responses to odors

A team of neuroscientists at the Champalimaud Centre for the Unknown (CCU), in Lisbon (Portugal), has performed one of the first studies into the central neural circuits (or higher brain areas) that underlie innate responses ...

Key mechanism of epileptic seizures reported

Russian scientists investigated the changes in the temporal lobe cortex of a rat brain during prolonged epileptic seizures. Despite the complex interaction of neural signals, biologists and physicists managed to build their ...

Drug homing method helps rethink Parkinson's

The brain is the body's most complex organ, and consequently the least understood. In fact, researchers like Michael Tadross, MD, PhD, wonder if the current research methods employed by neuroscientists are telling us as much ...

Vicious circle leads to loss of brain cells in old age

The so-called CB1 receptor is responsible for the intoxicating effect of cannabis. However, it also appears to act as a kind of "sensor" with which neurons measure and control the activity of certain immune cells in the brain. ...
