Single gene is responsible for most cool temperature sensation

The discovery, reported in the May 3 issue of the journal Neuron, might one day lead to the development of drugs that induce cold sensation as an analgesic, or block it to prevent certain forms of chronic pain associated with cold sensation.

Green tea shows potential for HIV-associated dementia prevention

A compound derived from green tea greatly diminished the neurotoxicity of proteins secreted by the human immunodeficiency virus, suggesting a new approach to the prevention and treatment of HIV-associated dementia, also known as AIDS dementia complex.

Ultra fast and ultra active: the strange life of the extraocular muscles

The eye, often called the window to the soul, may become a window to the mysteries of muscular dystrophy, a debilitating muscle disease that often leads to death in early adulthood.

New understanding of sleep

Sleep remains one of the big mysteries in biology. All animals sleep, and people who are deprived of sleep suffer physically, emotionally and intellectually. But nobody knows how sleep restores the brain.

Estrogen fluctuation affects epileptic seizures

In more than a third of women with epilepsy, seizures fluctuate across the menstrual cycle, due in part to continually fluctuating effects of estrogen on the neural circuitry in the hippocampus, a region of the brain involved in learning and memory - and in epileptic seizures.

Environment rich in sensory stimuli restores memory in mice with neurodegeneration

Mice whose brains had lost a large number of neurons due to neurodegeneration regained long-term memories and the ability to learn after their surroundings were enriched with toys and other sensory stimuli, according to new studies by Howard Hughes Medical Institute researchers.

Headaches may act like tiny transient strokes

Migraines may be doing more than causing people skull-splitting pain. Scientists have found evidence that the headaches may also be acting like tiny transient strokes, leaving parts of the brain starved for oxygen and altering the brain in significant ways.
