Implantable device hits targeted brain cells with light and drugs when triggered remotely

By - July 17, 2015 1 Picture

The field of optogenetics where individual brains cells are made to behave differently when exposed to light has wide-ranging potential. It may one day be used to reverse acquired blindness, alter pain thresholds and even hit the rest button on our biological clocks. With one eye on this emerging area of neuroscience, scientists have developed a device the width of a human hair that can be planted in the brain to deliver light or drugs only where needed, offering better targeted treatments and reduced side effects.

Connected brains share control of virtual limbs and predict the weather

By - July 13, 2015 1 Picture

If the thought of using a person's brainwaves to control a machine isn't quite enough to make the mind boggle, then mixing signals from multiple brains for the same purpose might just do the job. This far-fetched field of neuroscience is edging ever closer to real-world technology, with a number of recent research efforts achieving significant advances, with mind-controlled drone flight just one example. The latest step forward in this area sees the brains of separate animals hooked up and their combined motor and sensory information used for things like controlling a virtual arm, pattern recognition and even predicting the weather.

Juvenile plasticity returned to adult mice brains

By - May 20, 2015 1 Picture

By enabling the rigid brains of adult mice to return to the high levels of plasticity found in juvenile brains, scientists are opening new pathways to the treatment of brain injuries such as stroke. Back in 2013, researchers from Yale University reported the discovery of a molecular switch that achieved this result, and now scientists at the University of California, Irvine, have managed to make an old brain young again using a different approach.

Electronic memory may bring bionic brain one step closer

By - May 12, 2015 1 Picture

Using a matrix of nano-sized memristors, researchers working at the Royal Melbourne Institute of Technology (RMIT) and the University of California, Santa Barbara claim to have constructed the world’s first electronic memory cell that effectively mimics the analog process of the human brain. By storing memories as multiple threads of varying information, rather than a collection of ones and zeroes, scientists believe that this device may prove to be the first step towards creating a completely artificial, bionic brain.

The Hunger Pains: Mice genetically engineered to not feel them

By - April 28, 2015 1 Picture
Hunger pains are the bane of any dieter's existence, kicking in even when skipping a single meal and goading the sufferer to indulge their desire for food. Controlling hunger is now better understood as neuroscientists tease apart why we (well, our model mouse cousins) feel hunger. Mind-bendingly, the same researchers have used genetic therapies to create feelings of satiety where none would otherwise exist. Read More

Implanted micropump could deliver epilepsy drugs right into the brain

By - April 26, 2015 1 Picture
A promising new treatment for epilepsy directly targets the nerve cells, deep within the brain, that cause seizures. The treatment uses an electronic micropump and an anticonvulsant drug to inhibit the relevant areas of the brain without affecting healthy brain regions. It has had promising initial results on mice in vitro and will now be tested on live animals. Read More

Scientists close in on computers that work like the human brain

By - April 9, 2015 1 Picture
Scientists have been working since 2008 to develop technology based on memristors (short for memory resistors), which promise computers that need never boot up and function more akin to the human brain – like neurons, they can retain information and perform logic operations. Now scientists at Northwestern University have made a new breakthrough that may make possible brain-like computing capabilities. Read More
