During REM sleep, the brain hallucinates (i.e., dreams) in a paralyzed body, and the EEG activity recorded from the scalp resembles that seen during wakefulness. Atonia, or a complete loss of muscle tone, prevents us from acting our dreams and injuring ourselves dur...
the participants wereasked to somehow regulate activity in the posterior part of the brain to makea solid green disc as large as they could. they were told they would get a paidbonus proportional to the size of this disc, but they werenrsquo;t told anythingabout what the disc meant. the...
The electroencephalogram (EEG), for instance, is a typical signal used as an input for BCI applications and refers to the electrical activity recorded through electrodes positioned on the scalp. During the last decades, EEG-based BCI became one of the most popular noninvasive techniques. The EEG...
Amyotrophic lateral sclerosis(ALS).Also called Lou Gehrig's disease, this condition destroys the nerves which control your muscle function. ALS steadily progresses to paralysis (not being able to move) and an inability to breathe on your own. Cognitive function (how well you can learn or problem...
Some people hallucinate during sleep paralysis. They see all sorts of strange things. The hallucinations are happening because part of your brain is still in a dream state. Instead of seeing those weird and wacky images in your dreams, you’re seeing them in the room with you. ...

These tests are done overnight in a sleep laboratory and are not done at home. In polysomnography, brain activity, heart rate, breathing, muscle activity, and eye movements are monitored while people sleep. People may also be videotaped during an entire night's sleep to document limb ...
Brain–machine interfaces (BMIs) create closed-loop control systems that interact with the brain by recording and modulating neural activity and aim to restore lost function, most commonly motor function in paralyzed patients. Moreover, by precisely manipulating the elements within the control loop, ...
