Scientists are one step closer to understanding how the part of our brain central for decision-making and the development of addiction is organized on a molecular level. Researchers at Karolinska Institutet, in mouse models and with methods used for mapping cell types and brain tissue, were able to visualize the organization of different opioid-islands in… Read more

Injectable nanoparticles that convert sound waves, which can easily penetrate into the brain, into light, have been developed by Stanford researchers[1]. Optogenetics, a tool for controlling neurons with light, has given neuroscientists the ability to flip brain cells on and off more or less at will, revolutionizing neuroscience. Yet the technique faces a fundamental challenge… Read more

New research may clarify why the effects of deep-brain stimulation can differ so much — and indicate the way to advancing the treatment[1]. People with severe Parkinson’s disease or other neurological conditions that cause intractable symptoms such as uncontrollable shaking, muscle spasms, seizures, obsessive thoughts, and compulsive behaviors are sometimes treated with electric stimulators placed… Read more

You may be one of those people with white spots on the brain. They don’t spare healthy people, but sick individuals may be more vulnerable. If you smoke, the risk increases even more. You don’t notice them too much unless your doctor has you get into an MRI machine. Then you can see them, scars… Read more

Without hardly noticing, we make countless decisions: to turn left or right on the bus? To wait or to accelerate? To look or to ignore? In the run-up to these decisions the brain evaluates sensory information and only then does it generate a behavior. For the first time, scientists at the Max Planck Institute of… Read more
