The Limbic System The brain is a very complicated organ consisting of two halves known as hemispheres. There is a left hemisphere, which controls the right side of the body, and a right hemisphere which controls the left side of the body. Another way that the brain is classified in is lobes. There are four lobes that the brain consists of, the frontal lobe, the parietal lobe, the occipital lobe, and the temporal lobe. Most of the action that happens in the brain that is related to sleep is in the hypothalamus, which is located in the Limbic System next to the temporal lobe. The Limbic System is the part of the brain that works with emotions and motives through a network of neural structures; it consists of the hypothalamus, the pituitary …show more content…
These hormones that are released have to do with growth of the body and brain and when there is little to no sleep, there is little to no growth (Eve Van Cauter). An example of one of these hormones is the adrenocorticotropic hormone which helps the body’s cortisol level, or stress level (Adrenocorticotropic hormone, 2013). When there is too little of the adrenocorticotropic hormone there is a high chance of poorly functioning adrenal glands or Addison’s disease which is when the body doesn’t produce enough hormones causing side effects of fatigue, loss of weight and muscle, and darkened areas on the skin (Adrenocorticotropic hormone, 2013).
Effects of Sleep Loss
When a person has a large sleep debt (the amount of rest that the brain is lacking) the brain starts to slow down, the immune system weakens, and the body can gain or lose weight along with many other health problems, mentally and physically (Sleep Deprivation).

The majority of people who suffer from night terrors are children, but it is not unheard of in adolescents. Night terrors is when, during sleep, the person gets up and moves around, speaks in rambling, incoherent sentences, can appear scared, and have increased heart and breathing rates (Meyers, 2004). It is highly unlikely that the person will wake up during their night terror or even remember it once they have woken up the next day. Night terrors are not the same as sleep walking; sleep walking happens in the beginning of Stage 4 sleep and can be passed down through genetics, whereas night terrors happen in the beginning of REM sleep (Meyers,
It sends information for sleep, hearing, taste, and even eye movement. Corpus Callosum: The corpus callosum connects both hemispheres of the brain and allows them to relay messages between one another. People who have a severed corpus callosum can essentially function as 2 different people at the same time, with the left half of their body performing one task, and the right half another. Frontal Lobe: As the largest lobe in our brain, this lobe play a significant role in personality and impulse control.
Forebrain #3 The section I chose is the forebrain which controls the higher functions of the brain, such as thinking, decision making, and dreaming. I chose forebrain #3 which consists of the occipital lobes, parietal lobes, and the somatosensory cortex. The occipital lobes is the visual processing center of the brain containing most of the region of the visual cortex. The occipital lobes are involved in many functions including visual perception, color recognition, reading, comprehension, depth perception, and recognition of object movement.
While the brain has three main parts, the cerebrum, the cerebellum, and the brain stem. 2. Peripheral nervous system (PNS) PNS include Cranial Nerves and spinal Nerves. It is communication line between the CNS and the rest of the body.
It also has parts that are important for the level of consciousness and for sleep.
The midbrain is the smallest section of the brain, located near the middle of the brain, lying right above the pons. The midbrain serves to take the sensory information and send it upward, into the forebrain. The midbrain also assists the pons and medulla in regulating our sleeping
The brain is the most complex and magnificent organ of the human body. It controls the muscle movements, the secretions of glands,breathing and internal temperature. Every creative thought, feeling, and plan is developed by the brain. The brain acts as the body’s control center. The human brain can be divided into the forebrain, mid-brain and hind-brain.
Sleepless in American is a National Geographic documentary on the lack of sleep Americans are receiving each night. The film starts with the statistic that “40% of American adults are sleep deprived” and followed with different effects of sleep deprivation such as: weight gain, delayed reaction time, depression, anxiety, speeds the growth of cancer, and has been linked to Alzheimer’s disease. Although, there is no scientific evidence to support the need for sleep, it is an important process that allows our bodies to function properly. Several sleep studies have been performed to understand the effects sleep deprivation has on a person. The participants of the sleep trial only received four hours of sleep per night.
Parts of the brain and their functions: the frontal brain with controls the higher mental processes. The midbrain, which controls emotions, motivations and the limbic system. The hindbrain which controls movement, and lower mental functions. 3. Split brain: when the corpus callosum is split it destroys the connection between the left and right side of the brain.
(Ben-Joseph) As a child’s nervous system matures, their night terrors tend to disappear. (Ben-Joseph) The nervous system plays a major role in controlling the night terrors.
Night terrors are most easily defined as a disturbance in sleep. Male children are more prone to be diagnosed with night terror. As many as six percent of children have had night terrors at some point in their life, most commonly in the toddler and preschool years, even continuing up to adolescence. During night terrors the child may experience: • Rapid breathing
The human body slows down its functions even further with brain activity slowing down to where there are brief pulses of electrical activity (“sleep”, n.d). Nextly, comes NREM 3 where the brain spends most of the time. It is here where functions such as breathing and pulse reach their lowest levels. Not only this, but it is during this time where vital processes happen that allows the body to function. Some of the various processes that occur include bone repair, muscle repair,tissue growth, and human growth hormone (HGH) (“What happens sleep”,n.d), Once this repairative state of sleep passes, lastly , comes the most widely talked about stage known as REM.
The brain becomes aware and tries to wake itself up (“Sleep
Also, insomnia is also affecting the emotion. Lack of sleep can affect the mental state. I feel tired in the whole day can easily feel unhappy for something occurs. Not enough sleep so easy to feel tired at work, do the own thing and feel no anticipated ability to compete.
During the first hours of sleep delta sleep (stage 3 and 4) dominates and REM periods are short, but REM periods become longer and non-REM periods become more superficial as the night progresses(253, 254). The sleeper is most difficult to arouse during the first hours of sleep. Short moments of arousal into the waking state are usually interspersed throughout the night, most of them too short to be remembered in the morning. Furthermore, normal sleep is characterised by short, recurring bouts of accelerated pulse, EMG- and EEG-activation, and bodily movements, even though the sleeper does not become fully awake. Paediatric normal values of common neurophysiological sleep parameters, adapted from Coble (255, 256 , 257) are provided in Table 2.
