The EEG is definitely much easier. The EMG did hurt a little bit, but it wasn't as bad as I had expected. The good news is that they both last a very short time, about five minutes each in my case. I know you're not looking forward to the EMG, but both of these tests are ...
Below is a chart representing brain waves measured by anEEGwhen a person is awake, in REM sleep, and in non-REM sleep: Your brain is almost as active in rapid eye movement sleep as when it’s awake, which is whymost dreaming happens during this time. As a precautionary measure, part ...

The brain also starts to create sleep spindles, which are bursts of fast, brain wave activity. Sleep spindles are normally tracked on an electroencephalogram (EEG), which measures brain activity when you’re at rest or asleep. Spindles can occur in different regions of the brain. Furthermore,...
At consumer electronics tradeshows, it is common to see booths showcasing apps, sound machines and various types of wearables that suit the needs of the sleep deprived. These exhibits show examples of home use, bedside, or inside-the-bed devices to measure sleep, movement, heart rate, blood...
REM Sleep. Numbering the traces from top to bottom, 1 & 2 are electroencephalograms (EEG) of brain activity; 3 is an electrooculogram (EOG) of movement in the right eye; 4 an EOG of the left eye; 5 is an electrocardiogram (ECG) trace of heart activity. 6 & 7 are electromyograms ...
Video games can be attractive to those with ADHD because they typically offer immediate rewards, and there are often great incentives to reach the next stage of a game. This can encourage the user to play video games without stopping, especially if they’ve felt deprived of feelings of accompl...
These heightened dreams are most common during rapid eye movement (REM) sleep, a period of very deep sleep marked by eye motion, faster breathing, and lots of brain activity. In fact, during REM, your brain is almost as active as when you're awake. ...
