but it actually extends up into the forebrain and down into the hindbrain. The reticular formation is important in regulating the sleep/wake cycle, arousal, alertness, and motor activity.
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 du...
A brain-machine interface (BMI) uses brain activity directly without any motor involvement for activation of a computer or other external devices. A considerable amount of scientific literature was created on BMIs during the past 15 years but most of this literature is experimental in nature, cont...
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...
A groundbreaking study has revealed new brain regions that could help restore speech in people with Broca’s aphasia. Scientists are working toward a brain-computer interface that translates brain activity into spoken words, offering new hope for those who have lost their ability to communicate. Cre...
preventing paralysis and dementia, preventing the colds and promoting sleep, nutrients are absorbed through the lasting contact of the medicine pillow and the head, blood sugar level reduction, blood pressure reduction and blood fat reduction are facilitated, and the blood vessel circulation of the b...
Sleep deprivation triggers a set of bidirectional changes in brain activity and connectivity, depending on the specific cognitive or affective behaviours engaged. Changes in brain activity are observed when averaged across a session of task performance and during on-task performance, wherein marked brai...
Older children may use drugs or alcohol, behave in risky ways, or engage in unhealthy sexual activity. Without treatment, repeated childhood exposure to traumatic events can affect the brain and nervous system and increase health-risk behaviors (e.g., smoking, eating disorders, substance use, ...
and activity ratio [Table1]. The intensity of a given VS event was simply computed by spatially averaging the CBV signal in all brain voxels. The activity ratio is the proportion of ‘‘active pixels’’ as defined previously [Supplementary Fig.2] to detect the VS events. From these tempora...
But that doesn't mean that your feet aren't working -- there's still activity in them, such as blood flow, even when you're not actually moving them. So there's no hidden, extra potential you can tap into, in terms of actual brain space. But there's still so much to learn ...
