Fitting the patients with electrodes that applied 200 kHz electric fields to the scalp at regular intervals for up to 18 hours per day, the researchers observed that the brain tumors progressed to advanced stages much slower than usual (taking a median time of 26 weeks), and sometimes e...New device for stroke patients improves walking
...ient's foot is in the air or on the ground, and electrodes transmit painless electrical stimulation to the peroneal nerve to activate the calf muscle and correct their gait. Offered on an inpatient and outpatient basis, the NESS L300 has been shown to improve walking coordination, speed and blood flow, an...Meditation may fine-tune control over attention
...d the task, their brain activity was recorded with electrodes placed on the scalp. In some cases, two target numbers appeared in the series less than one-half second apart - close enough to fall within the typical attentional blink window. The research group found that three months of rigorous training in Vi...Study finds role of mid-brain in integrating heart and respiratory response to exercise

... from Shakespeare's plays. In this initial test electrodes were placed on the subject's scalp to measure brain responses. Professor Roberts said: "EEG gives graph-like measurements and when the brain reads a sentence that does not make semantic sense it registers what we call a N400 effect a negative wav...Sleep problems -- real and perceived -- get in the way of alcoholism recovery

Using electrodes finer than a human hair implanted into individual neurons, the researchers could monitor signals passed among neurons in the treated mice. They found the overall level of activity of the neurons in the motor cortex did not change. Instead, the neuron...Large subset of learning disabled children can be quickly identified by new diagnostic device

As the child watches a movie, researchers measure the brain's responses to the acoustic sounds. Once identified as part of the subset of learning disable...Tipsheet: Focus on gait training, pain relief, pressure ulcers and hearing aid training
