Have you ever thought how and from where thoughts come to our mind when at midnight especially when are trying to sleep? The most obvious answer is the brain. But did you know why it comes and the purpose of such thoughts.
The human
brain or Dimag is the largest and most developed brain of all vertebrates
relative to body size. The brain is the command center of the human body. It is
responsible for all nervous system activities. But it is not exactly what we
think; the process of the brain is more in our body. Sometimes it does extra
activities which may are daunting to us. So in this article, we will discuss
those facts which are new to everyone.
Fact 1- Sleep
The function
of sleep is still a mystery and the reason it happens to us. However, with modern research scientists are
giving clues that sleep is the act of the brain. Sleep helps to recharge our
body, a clear waste of the brain, increase memory, and support learning
ability. Moreover, sleep helps in regulating libido, minerals, and
appetite.
Sleeping is
not simple as it seems, it is an integral part of our life and it is more
complex than we think. Research shows that the brain has two types of sleep:
- Slow-wave sleep (SWS)
- Rapid Eye Movement (REM) or dreaming sleep
Most of the
time we sleep under SWS variety, it can distinguish by relaxed muscles, slow
and deep breathing, large and slow brain waves that help the brain and body to
recuperate while sleeping. While the sleeping brain does not completely
turn-off by it goes on recovery mode. A series of highly orchestrated
activities puts the brain to sleep in stages. It starts in the brain areas that
later produce SWS. The reason behind the SWS phenomenon is the activity of two
group cells- the ventrolateral preoptic nucleus in the hypothalamus and the
parafacial zone in the brain stem. These cells when triggered can lead to loss
of consciousness.
REM is the
next stage after SWS. In this mode, brains become slightly active while the
body and muscles remain inactive. Also, it turns breathing and heart rate
erratic. The REM sleeps is still a mystery, despite our advancement and
understanding of science.
However, the reason behind this sleep is a small group of cells called the subcoeruleus
nucleus. REM sleep occurs when these become diseased or injured. It does not
cause muscle paralysis. This can lead to serious sleep behavior disorder, it is
a serious condition that afflicted violently act out their dreams.
