By Paul McClure | October 24, 2023 Using magnetic stimulation on the brain of a man who had a stroke 12 years ago improved his movement and coordination, a case study has shown. Einstein et al./UCLA Health Researchers have used repetitive magnetic stimulation on the brain of a man who’d had a cerebellar stroke 12...
HEALTH 28 May 2023 By DAVID NIELD (Flavio Coelho/Moment/Getty Images) Stimulating the brain with magnetic fields can help relieve the symptoms of depression in some people, but scientists haven’t been sure precisely why it works. A new study offers some insight: The process reverses brain signals going in the wrong direction. These neural streams of activity going in the...
By Michael Irving May 17, 2023 Stanford scientists have uncovered a new mechanism behind depression – and shown how magnetic stimulation can help treat it. Depositphotos Stanford scientists have discovered a major biological mechanism behind severe depression, and shown how to treat it. Signals between two key parts of the brain seem to flow the...
MEDICAL COLLEGE OF GEORGIA AT AUGUSTA UNIVERSITY IMAGE: AMOL SHARMA, MD CREDIT: MICHAEL HOLAHAN, AUGUSTA UNIVERSITY AUGUSTA, Ga. (May 16, 2023) – Magnetic stimulation of a group of nerves key to how our gut and brain communicate may help correct the conversation that goes awry in painful, debilitating diabetic gastroparesis, researchers say. Patients come to Amol Sharma, MD, because...
Transcranial magnetic stimulation (TMS) is a procedure that uses an electromagnetic coil close to the skull to deliver magnetic pulses into the brain. These pulses can alter nerve cell activity in areas of the brain involved in mood regulation, which may help treat anxiety. It is typical to experience occasional anxiety, but if someone feels frequently...
Recently, actor Bruce Willis announced that he would step away from his acting career due to complications resulting from aphasia. Aphasia is the loss or impairment of the ability to speak or write. It can result from damage in the brain area that controls language expression and comprehension. Damage can result from stroke, head injury, brain tumor,...

by Paul Fitzgerald, The Conversation Credit: www.shutterstock.com A line in this week’s federal budget allocating A$288.5 million to repetitive transcranial magnetic stimulation (rTMS) therapy might pass most people by. This is a brain stimulation technique that’s been used to treat conditions such as depression for almost ten years in Australia, but which has not been funded through Medicare and so has...
by Rice University A sample of Rice University’s ‘magnetoelectric’ film atop a bed of uncooked rice. Rice neuroengineers created the bi-layered film to power implantable neural stimulators that are approximately the size of a grain of rice. The film converts energy from a magnetic field directly into an electrical voltage, eliminating the need for a...
