The brain is a precision instrument. Its function depends on finely calibrated electrical activity triggering the release of chemical messages between neurons. But sometimes the brain’s careful balance is knocked out of control, as in epilepsy. Electroencephalography, or EEG, visualizes a brain’s electrical activity and can reveal how an epileptic seizure diverges from the predictable

Synapses, the structures that allow neurons to pass signals to one another, are essential to neuronal function. Proper formation and responses to stimulation of synapses both during development and in adulthood are fundamental to mammalian brains, but the molecular processes governing formation and modulation of compartmentalized synaptic assemblies are unclear. In a recent study, a

A low-calorie diet causes different metabolic effects in women than in men, a new Diabetes, Obesity and Metabolism study suggests. In the study of more than 2,000 overweight individuals with pre-diabetes who followed a low-calorie diet for 8 weeks, men lost significantly more body weight than women, and they had larger reductions in a metabolic

It is common for adults to have between 10 and 40 moles. People with lighter skin tend to have more moles than those with darker skin. Moles can change as a person ages. Some will become darker or lighter, and many moles grow. They can appear anywhere on the skin, from the scalp to the

Phantosmia is also called a phantom smell or an olfactory hallucination. The smells vary from person to person but are usually unpleasant, such as burnt toast, metallic, or chemical smells. Problems with the nose, such as sinusitis, or conditions of the nervous system or brain, including migraine, stroke, or schizophrenia can cause phantosmia. In this

In this article, we explore several components of a healthful post-workout snack and describe how they benefit the body. The importance of the post-workout snack During exercise, the muscles use up stored glucose, called glycogen, and levels become depleted. Endurance sports, such as running, use up more glycogen than resistance activities, such as weightlifting. Another

There seems to be a lot of confusion regarding the value – or lack thereof – of muscle stretching to accelerate recovery after exercise. “Stretching clears out your lactic acid,” and other similar claims abound. Is any of this true? Sort of. First, it is important to understand the difference between stretching for recovery and

Each type causes different symptoms, and they can affect different parts of the body. There is no cure for either HPV or herpes. In this article, we look at the
