Researchers at UNSW have for the first time used electrical pulses delivered from a cochlear implant to deliver gene therapy, thereby successfully regrowing auditory nerves.The research also heralds a possible new way of treating a range of neurological disorders, including Parkinson’s disease, and psychiatric conditions such as depression through this novel way of delivering gene therapy.

A novel compound that targets an important brain receptor has a dramatic effect against a host of cocaine addiction behaviors, including relapse behavior, a University at Buffalo animal study has found. The research provides strong evidence that this may be a novel lead compound for treating cocaine addiction, for which no effective medications exist. In the study, the compound, RO5263397, severely blunted a broad range of cocaine addiction behaviors.

Scientists from the Florida campus of The Scripps Research Institute (TSRI) have identified a protein complex that plays a critical but previously unknown role in learning and memory formation. The study, which showed a novel role for a protein known as RGS7, was published April 22, 2014 in the journal eLife, a publisher supported by the Howard Hughes Medical Institute, the Max Planck Society and the Wellcome Trust.

A new study from a large multi-national group of scientists suggests that absolute brain size is key in evolution of cognition and self-control. The study, published in early edition in the journal Proceedings of the National Academy of Sciences examined 36 animal species in two problem-solving tasks measuring self-control. It found that absolute (not body size- relative) brain size and dietary breadth were the major predictors of species differences in self-control.

Despite decades of common use for surgeries of all kinds, the precise mechanism through which general anesthesia works on the body remains a mystery. This may come as a surprise to the millions of Americans who receive inhaled general anesthesia each year. New research led by the Perelman School of Medicine at the University of Pennsylvania investigated the common anesthetic sevoflurane and found that it binds at multiple key cell membrane protein locations that may contribute to the induction of the anesthetic response.

Researchers at UT Southwestern Medical Center are making breakthroughs that could benefit people suffering from depression. A team of physician-scientists at UT Southwestern has identified a major mechanism by which ghrelin (a hormone with natural anti-depressant properties) works inside the brain. Simultaneously, the researchers identified a potentially powerful new treatment for depression in the form of a neuroprotective drug known as P7C3.
