New research has raised the possibility that human retinas may someday be induced to regenerate themselves, thus restoring vision. Fish retinas have this self-regeneration ability, and it was while investigating the phenomenon in zebrafish that biologists from Vanderbilt University discovered a “signal” that appears to trigger the self-repair process. If confirmed by follow-up studies, the… Continue reading Fish May Hold the Key to Curing Eye Illnesses

Sleep Apnea and Brain Chemicals
Researchers have discovered that people with sleep apnea showed changes in two important brain chemicals – and those changes may be why many sufferers are significantly affected by the condition. The finding was published in the Journal of Sleep Research. One in 15 adults has moderate to severe obstructive sleep apnea, a disorder in which… Continue reading Sleep Apnea and Brain Chemicals
En Route to Better Treatment of Parkinson’s
Researchers now know why long-term use of L-DOPA (levodopa), an effective treatment for Parkinison’s disease, causes a problem known as dyskinesia, or excessive movement. Using a new method for manipulating neurons in a mouse model of Parkinson’s, a Columbia University Medical Center (CUMC) research team found that dyskinesia arises when striatonigral neurons become less responsive… Continue reading En Route to Better Treatment of Parkinson’s
