New study explores reliability of optogenetics as method of intervention of temporal lobe seizures

Optogenetics is one of the hottest tools in biomedical research today, a method that uses gene therapy to deliver light-sensitive proteins into specific cells. This new tool allows researchers to interact with a single cell or a network of cells with exquisite precision. Whereas imaging and other technologies allow researchers to watch the brain in action, optogenetics enables them to influence those actions.

Epilepsy: A true window on the brain

Rapidly emerging technologies, novel imaging techniques, the development of new therapies and new genes, have given researchers and clinicians an extraordinary ability to explore the brain at the cellular, genetic and neural levels. While current epilepsy research may seem like it's ripped from the pages of a science fiction novel, it's real—and even pretty cool.

Light-activated diabetes drug: an interview with Dr David Hodson

We've known about chemicals that can be light-activated for about five to ten years now. They’ve mainly all been applied to neurons and, more specifically, the retina. Nobody has ever really looked at any tissues outside of the nervous system.

Researchers use light to erase specific memories in mice

Just look into the light: not quite, but researchers at the UC Davis Center for Neuroscience and Department of Psychology have used light to erase specific memories in mice, and proved a basic theory of how different parts of the brain work together to retrieve episodic memories.

Novel technique uses genetic tool and light to map neural networks

For years, neuroscientists have been trying to develop tools that would allow them to clearly view the brain's circuitry in action-from the first moment a neuron fires to the resulting behavior in a whole organism.

Study for better understanding of neural circuitry and dynamic mechanisms controlling memory

A study just published in the prestigious Nature Neuroscience journal by, Sylvain Williams, PhD, and his team, of the Research Centre of the Douglas Mental Health University Institute and McGill University, opens the door towards better understanding of the neural circuitry and dynamic mechanisms controlling memory as well of the role of an essential element of the hippocampus - a sub-region named the subiculum.

Brain's motor cortex can directly turn down hearing

When we want to listen carefully to someone, the first thing we do is stop talking. The second thing we do is stop moving altogether. This strategy helps us hear better by preventing unwanted sounds generated by our own movements.

Researchers endow mice with greater touch sensitivity by striking brain rhythm

By striking up the right rhythm in the right brain region at the right time, Brown University neuroscientists report in Nature Neuroscience that they managed to endow mice with greater touch sensitivity than other mice, making hard-to-perceive vibrations suddenly more vivid to them.

Scientists discover area of brain that could control person's motivation to exercise

Scientists at Seattle Children's Research Institute have discovered an area of the brain that could control a person's motivation to exercise and participate in other rewarding activities - potentially leading to improved treatments for depression.

NIH-funded study explores how thalamic reticular nucleus influences consciousness

Ever wonder why it's hard to focus after a bad night's sleep? Using mice and flashes of light, scientists show that just a few nerve cells in the brain may control the switch between internal thoughts and external distractions.

New techniques offer insight into cell-by-cell makeup of organisms

In general, our knowledge of biology-and much of science in general-is limited by our ability to actually see things. Researchers who study developmental problems and disease, in particular, are often limited by their inability to look inside an organism to figure out exactly what went wrong and when.

New technology in field of optogenetics can remotely control specific receptors by light

Institute for Basic Science (IBS), the main organization of the International Science and Business Belt project in South Korea, has announced that a group of researchers, led by professor Won Do Heo, have developed a new technology in the field of optogenetics that can remotely control specific receptors by light.

Light-sensitive molecule enables noninvasive silencing of neurons

Optogenetics, a technology that allows scientists to control brain activity by shining light on neurons, relies on light-sensitive proteins that can suppress or stimulate electrical signals within cells. This technique requires a light source to be implanted in the brain, where it can reach the cells to be controlled.

Neuroscientists can control muscle movement by applying optogenetics

For the first time, MIT neuroscientists have shown they can control muscle movement by applying optogenetics - a technique that allows scientists to control neurons' electrical impulses with light - to the spinal cords of animals that are awake and alert.

Scientists use a flash of light to erase and restore memory

Using a flash of light, scientists have inactivated and then reactivated a memory in genetically engineered rats. The study, supported by the National Institutes of Health, is the first cause-and-effect evidence that strengthened connections between neurons are the stuff of memory.
