The state of consciousness continue to puzzles neuroscientists worldwide. However, a team of neurologists and neurosurgeons have succeeded in increasing conscious control in an individual who had been in a minimally conscious state (MCS) for over six years.
Irritable bowel syndrome (IBS) affects 10 to 15 percent of the U.S. population, predominately women, and can produce severe abdominal pain, bloating, and changes in bowel habits. No physical abnormalities can be identified on examination, and patients are often left with suboptimal symptomatic treatments and the idea that the pain is "all in your head." Well, maybe it is.
Let's Start with Rats With visions of hangovers dancing in many readers' minds (and brains), and in the minds of whoever saw them doing what people do when they are intoxicated (or saw it on YouTube.com); I thought I'd bring your attention to some rats. Science is learning more about why alcoholics are able to stay in denial, and why anyone should be afraid of bingeing.
One of the greatest challenges neurologists face is successful delivery of drugs to the brain. This is because a special filtering layer of tissue, called the blood brain barrier, protects the brain and spinal cord. The barrier acts like a molecular sieve, allowing only properly sized molecules through. This means that any medication needing to reach the brain (for example, to kill a brain tumor) needs to be small enough, and even then, it is difficult to target the drug to specifically reach the brain.
