- Optogenetics: Illuminating When Brain Cells Switch Off ()
Scientists at Scripps Research Institute have created a groundbreaking method to track when brain cell activity decreases or switches off after a burst of activity using a combination of optogenetics and proteomics. “Neuronal dynamics involve both the increase and decrease of activities; yet, for a long time, there have only been trackable histological markers for […]
- An expanding molecular toolbox untangles neural circuits ()
Life is full of nervous reactions — a head snaps towards a voice, leg muscles tense at the sound of a starting gun and thirsty mice scamper towards a squirt of water when trained to respond to a certain tone. The mechanisms behind such reward-related behaviours are notoriously difficult to unpick. Nerve cells often snake […]
- Wireless Light Implant for Optogenetics Without Skull Damage ()
Researchers at the University of Arizona have overcome a major limitation of optogenetics with their wireless and battery-free implant that can shine light through the skull. The small device, which is implanted under the skin, could provide a light source for optogenetics that doesn’t require damage to the skull or brain. While optogenetics is currently […]
- Tiny Machine Poised to Unlock Brain’s Mysteries ()
Researchers have developed a new device that can record, sense, and manipulate brain organoids. The device will allow researchers to make groundbreaking discoveries about how the brain develops and identify mechanisms of recovery following trauma.

- The Feng lab has developed a next-generation optogenetic system for non-invasive stimulation of neurons ()
Optogenetics has revolutionized neurobiology, allowing researchers to use light to activate or deactivate neurons that are genetically modified to express a light-sensitive channel. This ability to manipulate neuron activity has allowed causal testing of the function of specific neurons, and also has therapeutic potential to reduce symptoms in brain disorders. However, activating neurons deep within […]
- The optogenetics scientific zone/industry ()
Hello, I think that right now optogenetics are able to move only 1 neuron or so. But maybe in the future, when research will go up in this area of science, optogenetics, when optogenetics will be able to move or to touch or to change more than 1 neuron in a single moment, maybe it […]
- Researchers Use Next-Generation Optogenetics to Control Single Neurons ()
Using a technique that relies on a new type of light-sensitive protein, researchers have devised a way to control single neurons using optogenetics. Researchers at MIT and Paris Descartes University have developed a new optogenetic technique that sculpts light to target individual cells bearing engineered light-sensitive molecules, so that individual neurons can be precisely stimulated.
