Magnetic Micro-coils May Provide More Precise Neural Stimulation

The next generation of brain implants could be tiny metal coils. Massachusetts General Hospital (MGH) researchers have developed a significant improvement in the technology behind brain implants used to activate neural circuits responsible for vision, hearing or movement. Lead author Seung Woo Lee, PhD, of the MGH Department of Neurosurgery, explains: “Neural stimulation systems based […]

Prostaglandin E2 Helps Regulate Breathing In Brainstem Model

The control of breathing is crucial for life. Without a proper response to increased carbon dioxide levels, people can suffer from breathing disturbances, sickness, and panic. In worst-case scenarios, such a deficit can lead to premature death, as in sudden infant death syndrome. How the brain controls breathing has been a subject of some debate […]

Manipulating Brain May Ease Pain Of Drug Withdrawal

In addition to the desire to experience a “high,” one of the obstacles drug addicts encounter is the difficulty of overcoming a myriad of harsh withdrawal symptoms, including anxiety, depression, nausea, vomiting, and diarrhea. When people learn to associate the loss of drug use with the pain of withdrawal, it can create an urge to […]

Graphene-Based Interfaces Do Not Alter Target Nerve Cells

Researchers have successfully demonstrated how it is possible to interface graphene – a two-dimensional form of carbon – with neurons, or nerve cells, while maintaining the integrity of these vital cells. The work may be used to build graphene-based electrodes that can safely be implanted in the brain, offering promise for the restoration of sensory […]

Trigeminal Nerve Stimulation Holds Promise For PTSD Treatment

An average of 30 years had passed since the traumatic events that had left them depressed, anxious, irritable, hypervigilant, unable to sleep well and prone to nightmares. But for 12 people who were involved in a UCLA-led study— survivors of rape, car accidents, domestic abuse and other traumas— an unobtrusive patch on the forehead provided […]
