A major form of one of the most prevalent inherited neurological disorders in humans, Charcot Marie Tooth disease (CMT), stems from an abnormality in the cellular powerhouses, or mitochondria, that fuel the nerves required for muscle control.

Without even a scar on her scalp, Paula Alters had major brain surgery. That is to say, a tumor was removed from her brain and a knife never came close to her head.

Researchers report that people with key variations in a gene that affects the ability of blood vessels to relax are 10 times more likely to suffer a stroke from a ruptured brain aneurysm than people who have aneurysms but lack these key genetic variations.

That's the conventional wisdom for why the human brain gradually became three times larger than the ancestral brain. But bigger brains were not generally smarter brains.

Neurobiologists have found that switching off a single gene for a neuronal protein prevents epilepsy in a mouse model of human epilepsy. They said their research offers the hope of drugs that could prevent the alterations in the brain that cause the normal brain to become epileptic.

Serotonin is a "neurotransmitter," a chemical that one neuron uses to trigger a nerve impulse in its neighbors. Thus, serotonin levels can profoundly affect brain function, and therefore behavior.

Infinitesimal particles of gold have enabled neurobiologists to track down key molecules in the machinery of "entry points" in neurons, offering clues to the organization of a region that has thus far remained largely unknown neuronal territory.

The Duke study is the first to identify where the cln3 protein resides in human brain cells and to link the protein's location to its function. The researchers discovered that cln3 transports a vital lipid, or complex fat molecule, within a cell.
