There are four stages of sleep: Stage one shows low-voltage‚ high-frequency signals on an EEG similar to those produced while awake‚ though slightly relaxed. There is slow voltage increase with an immediate drop in frequency through development in stages. Stage two is marked by two diverse wave formations called a K complex and a sleep spindle. Stage three is interrupted by an intermittence of delta waves which are great and measured‚ while stage four is predominantly delta waves. (Pinel‚ 2007) After

ECT TREATMENT REFLECTION PAPER Today I was able to familiarize myself with indication‚ contraindications and nursing care of ECT patient before‚ during and after the procedures. ECT is a medical treatment for severe mental illness in which a small‚ carefully controlled amount of electricity is introduced into the brain. This electrical stimulation‚ used in conjunction with anesthesia like propofol and muscle relaxant medications like saxicoline‚ produces a mild generalized seizure or convulsion

In this practical an electroencephalogram was carried out. An electroencephalogram (EEG) is a test that measures the brain waves and electrical activity of the brain by way of field potentials. It is used in both awake and asleep states. The human brain allows functions of various mechanisms to occur by communication within the brain. The communication within the brain is done through neurons of various sorts‚ sending action potentials through various regions. Each region in the brain will have specific

What really goes on when we sleep? At first glance sleep is just simply sleep but so much more is going on. When we(humans) go to sleep we cycle through four different stages of sleep. Each of the four cycles are significant. When we initially fall asleep the first cycle is called the NREM1 stage. The next stage is the NREM2 stage and consist of periodic sleep spindles (Excelsior‚ 4TH 16‚ p. 1.18). The third stage is the NREM3 sleep and this simply means you are in the threshold of that deep sleep

Sleeping and Dreaming By Cindy J. Velasco PSY/240 The Brain‚ The Body‚ and The Mind Mr. Lowell Brubaker March 21‚ 2013 There are three ways that sleep is measured by using‚ EEG- Electroencephalogram‚ EOG- Electrooculogram‚ and EMG- Electromyogram. In order to measure sleep they use EEG‚ EOG‚ and EMG to categorize the sleep stages. As we sleep we hit four different stages of sleep. The first stage is stage 1 EEG or initial stage 1 EEG which is described as a low-voltage‚ high-frequency

Altered States of Consciousness Consciousness is a state of awareness. This includes a person’s feelings‚ sensations‚ ideas‚ and perceptions. There are many different states of consciousness. Sleep is a state of altered consciousness‚ characterized by certain patterns of the brains activity and inactivity. An altered state of consciousness is when a person is not completely aware of their surroundings. Some researchers believe that we sleep to clear our minds of useless information

Argument for Dreaming Rene Descartes – one of the most recognized philosophers of all time has presented us with many arguments in his pursuit to demolish skepticism in his book “Meditations on First Philosophy.” The subject of this paper will be the argument for dreaming which he assesses in said writing. The argument seeks to prove or disprove the fact that one can know that one is not dreaming at any given moment. It is easy to jump to the conclusion that the idea that you are sleeping right

CHIEF COMPLAINT Balance problems. HISTORY OF PRESENT ILLNESS This patient is a 54-year-old woman who complains of swaying when she is standing or even sitting for long periods. She loses her balance when she is standing to wash the dishes or brush her teeth or fix her hair. It does not matter if her eyes are open or closed‚ although it is much worse when she closes her eyes. This started at least as long ago as last spring and has been getting progressively worse. In the last couple of weeks

Homeostasis‚ in general‚ the sleep-wake cycle is regulated by two separate biological mechanisms in the body which interact together and balance each other. Studies say that high levels of adenosine leads to sleepiness. According to the two process model of sleep regulation the timing and structure of sleep are determined by the interaction of a homeostatic and a circadian process. The original qualitative model was elaborated to quantitative versions that included the ultradian dynamics of sleep

1. Define an electrocardiogram. An electrocardiogram is a recording of the electric activity of the heart. An electrocardiogram (E.C.G) is a simple‚ noninvasive procedure. Electrodes are placed on the skin of the chest and connected in a specific order to a machine that‚ when turned on‚ measures electrical activity all over the heart. Output usually appears on a long scroll of paper that displays a printed graph of activity on a computer screen. 2. What are the four types of brain waves and distinguish
