When designing neuroprosthetic devices for users to control with their thoughts, engineers must take into account the sensory information brains collect from the environment and how it gets processed.
Distraction or performance enhancer?

Research shows that the type of task – and style of music – tend to determine whether listening will help or hinder your performance.
Neurostimulation is rife with potential and pitfalls.
From dementia to depression to drug addiction, artificial brain stimulation has been hailed as a landmark medical technology for the future. But safeguards are needed if we want the benefits without the risks.
Could it be this easy?
We know things like exercise can increase our brain function, but taking a pill would require less effort.
Dr. Zahra Moussavi tests a device that stimulates the brain with magnetic pulses. The experimental technology can temporarily roll back effects of Alzheimer’s disease.
When Zahra Moussavi’s mother developed Alzheimer’s, the scientist pursued a technology that directly stimulates the brain with electromagnets to mitigate the effects of the disease. It worked.
Inspiration can come when we least expect it.
Many writers say they have inspiration come to them from their characters or an inner voice. Science is seeking answers.
Is electrical pulse to the brain your favorite memory enhancer?

Tinkering with the brain’s electrical field shows tantalizing promise for boosting memory, but it doesn’t always work. A new study offers one reason why.
About half of studies of some types of brain stimulation cannot be reproduced. So, how do we know if these work?
Electrical brain stimulation is used to treat a range of conditions, from depression to epilepsy. But how confident can we be that it works?
Bulimia is a debilitating condition.
Can new ways of using electric currents to stimulate the brain help reduce symptoms of one of the most debilitating eating disorders?
Talk to users of electronic brain stimulation.

People who electrically stimulate their brains at home need more information to do it safely… and neuroscience needs to find out more about how and why they do it.
Think hard before taking it to the next level.
Brain stimulating headsets are being enthusiastically taken up by gamers aiming to boost performance. But there are risks, particularly for children or those vulnerable to mental health problems.
For people with severe depression, incorrect application can worsen their condition or cause memory loss.
Around 350 million people worldwide have depression. Antidepressant medications are often prescribed to treat the condition, alongside talking therapies and lifestyle changes such as regular exercise…
Who doesn’t want more brain power?
The practice of physically stimulating the brain in order to alleviate symptoms of illness and injury has been around since the early 20th century. For example, electroconvulsive therapy (ECT) is still…
