The brain waves associated with REM sleep are most similar to those of an awake and alert state. During REM sleep, the brain exhibits a mix of high-frequency beta waves and low-amplitude alpha waves, resembling the patterns observed when a person is awake and engaged in active thought. This similarity is why REM sleep is often associated with vivid dreaming and increased brain activity.

How do I keep my mind awake while keeping my body asleep?
You can't. It is your brain (mind) that needs sleep. Your body does not.I don't believe that's correct. According to research I read about some time ago, there are certain brain wave changes that take place once a person falls asleep. Within 1-2 hours, depending on the individual, those brain waves return to the same levels at which they were when the person was awake. This led those researchers to conclude that, while both the body and mind benefit from sleep, the body needs it more; the brain only needs a couple of hours or less.Sorry mate, but that is nonsense. The electroencephalographic signature of the brain is quite distinct during all stages of sleep, and these patterns differ markedly from those associated with conscious activities. In any case you would need to cite your sources. The bottom line - and best answer to this question - is your body needs REST, not sleep per se. Your brain needs the refreshment only healthy sleep provides.
Why is REM sleep also called Paradoxical sleep?
Because during a REM stage your brain produces waves with a frequency and amplitude similar to beta waves. Beta waves have short frequencies and low amplitudes. These are the waves that are most common when you are most awake. Basically: you look asleep, but your brain is wide awake. REM sleep is when we remember our dreams, so it makes sense that our brains are most active when we are dreaming, seeing as that dreams require a lot of mental activity.
How do you combineA gray whale has a brain the size of a cars engine Its brain is large?
A gray whale has a brain comparable in size to a car's engine, indicating that it possesses a large brain. This significant brain size suggests potential for complex behaviors and cognitive abilities, similar to those seen in other intelligent marine mammals. Such a large brain is often associated with advanced social interactions and problem-solving skills in animals.
How does sleep affect brain activity?
It's not surprising to learn sleep deprivation can have negative affects on how well you process and remember information. Read below to learn more about how sleep affects the mind.Sleep deprivation affects brain functionAs you sleep memories are shifted to more efficient areas in your brain. This makes procedural skills, such as playing sports or interpreting complex information, more automatic than in those who are sleep deficient. (1)Positive brain functions are more active in rested individualsBrain scans called Functional Magnetic Resonance Imaging (fMRI) show those receiving sufficient amounts of sleep have more active cerebellums, the part of the brain known for controlling mental speed and accuracy. (1) (2) Sleep may improve moodThe limbic system of the brain manages emotions. Well rested individuals who also underwent fMRI scans showed less activity in this area, a finding that has been consistent with positive attitudes and lower levels of anxiety.(1) Sleep Apnea causes HypoxiaOxygen deprivation, or hypoxia, occurs whenever one has an apneic event. A recent study indicates those enduring hypoxia during sleep are more likelyto have cognitive impairments. (3)Brain activity varies in rested vs unrested individualsWhen deprived of sleep individuals showed activity in a different part of their brain than when rested. This suggests one part of the brain may compensate for inactivity in another part. (2) Sleep promotes memory retentionChanges occurring in the brain during sleep help improve memory, which may explain why infants and those suffering brain trauma require more sleep than healthy adults.

What disorder would cause paralysis or seizures only when asleep?
Although not associated with seizures, you may be thinking of sleep paralysis. Sleep paralysis is a disorder characterized by the inability to move upon falling asleep or waking up. Sleep paralysis occurs as a person is moving in our out of rapid eye movement (REM) sleep, and is the result of a premature disconnection between the brain and body. While the brain and body normally disconnect during REM sleep, those who suffer from sleep paralysis experience the disconnection as they are about to enter or exit REM instead. Symptoms of sleep paralysis include: * Sensations of noise or smells * Feelings of levitation * Inability to move the body * Feelings of terror * Images of intruders Sleep paralysis can be caused by any incident that disrupts normal REM patterns, including jet lack, insomnia, inconsistent sleep hygiene, and brain injury. The best way to banish sleep paralysis is to reestablish normal REM patterns. Going to bed and rising at the same time every day will reintroduce a normal brain-body connection.
What are the precautions associated with using Yerba santa?
Not to be taken by pregnant or nursing women or those with chronic gastrointestinal disorders, sleep disorders or bouts of insomnia.
Why is Yiruma associated so much with the film Twilight?
He isn't. Some of his songs are confused with those in the film because they are very similar.
Is there a symbol for meningitis?
Meningitis does not have it's own symbol. However it is associated with the protective membrane of the brain and spine since those are the areas it effects the most.
What body part relates to miniature general?
The hippocampus in the brain is associated with the formation of new memories, including those related to personal experiences and events.
What are the potential dangers associated with the false doctrine of soul sleep?
The potential dangers of the false doctrine of soul sleep include confusion about the nature of the afterlife, lack of urgency in spiritual matters, and potential for manipulation by those who promote this belief.
What is an abnormal sleep study?
It is a sleep study which shows patterns other than those associated with normal sleep stages architecture. The lighter sleep stage is stage 2, and the deeper stages are 3 and 4, followed by a brief period of REM sleep, before the sleep cycle repeats itself. A healthy night's sleep typically includes five 90 minute sleep cycles. A common abnormal sleep study is one which is associated with multiple apneic episodes, pointing to sleep apnea as a problem (which limits the body's ability to attain the deeper stages of sleep, hence the fatigue and sleepiness the next day despite the subjective perception that one has slept for eight hours or more).
