A popular anti-insomnia medication, zolpidem (Ambien, sanofi-aventis US), increases the ability to remember images, but only those that have negative or highly arousing content, new research shows.

It takes strong legs and, above all, a big heart to run a 1500km ultra-marathon.
But, fuelled by his love for his nan, nothing can break the stride of Wangaratta teenager Lachlan Cameron.
New high-resolution, 3-D model could speed brain research, help doctors treat neurological diseases
An international team of scientists report they've assembled the first three-dimensional model of the human brain that maps its anatomy on a cellular level.
When 23-year-old Jacob Landis was only 2, his mother suspected that something might be wrong. Jacob wasn’t learning to talk as quickly as his peers, and a hearing test confirmed her suspicions. For the next few years, his hearing faded away—first gradually, and then at breakneck speed.
It can be used to describe the feeling we get when we stand up quickly and feel unbalanced, that unstable feeling of movement when we are standing still or the feeling just before passing out.

Researchers from the Navy, the National Aeronautics and Space Administration and academia are studying causes and potential treatments of motion sickness, hoping to formulate better products for situations that range from the extreme (space!) to the mundane (road trip to Grandma's, anyone?).

Individuals with no experience in meditation who participate in mindful meditation training sessions for as little as 4 days show changes in specific brain mechanisms that correlate with a reduction in anxiety, a new imaging study shows.
Many disorders of the inner hear which affect both hearing and balance can be hugely debilitating and are currently largely incurable. Cochlear implants have been used for many years to replace lost hearing resulting from inner ear damage. However, to date, there has not been an analogous treatment for balance disorders resulting from inner ear disease. One potential new treatment is an implantable vestibular prosthesis which would directly activate the vestibular nerve by electrical stimulation. This prosthetic treatment is tested in a new study by Christopher Phillips and his colleagues from the University of Washington in Seattle, USA. Their findings are published in the Springer journal Experimental Brain Research.
A team of NIH-supported researchers is the first to show, in mice, an unexpected two-step process that happens during the growth and regeneration of inner ear tip links. Tip links are extracellular tethers that link stereocilia, the tiny sensory projections on inner ear hair cells that convert sound into electrical signals, and play a key role in hearing. The discovery offers a possible mechanism for potential interventions that could preserve hearing in people whose hearing loss is caused by genetic disorders related to tip link dysfunction. The work was supported by the National Institute on Deafness and Other Communication Disorders (NIDCD), a component of the National Institutes of Health.

Yet when a rare condition caused his ear to pick up the noises inside him, it nearly drove him mad.
