Words formed into melodies have been the most powerful message‚ allowing people to comprehend emotion for over 5‚000 years. The way words are placed between beats gives a hypnotic message to your body and changes the state of your brain. But is music just that? A series of notes and precisely placed words? This is what I have set out to discover. What effect does music have on humans? When listening to a good song you feel a sense of relaxation and calm within your body. Often we stop what we’re

Polysomnography is a sleep study test performed by a qualified sleep technologist in an effort to diagnose sleep disorders. Sleep is defined as a “naturally occurring state of unconsciousness‚ diminished activity of the skeletal muscles‚ and depressed metabolism from which a person can be awakened by stimulation” [AP]. A polysomnogram is a recorded study used to measure multiple physiologic variables and phases of sleep. This involves the use of certain equipment which allows the polysomnographist

To feel happy is something that seems to be a universal desire. However defining the feeling of happiness is not an easy thing to do. It can be described as a range of positive emotions ranging from contentment to joy (Spoors et al 2011). There are many factors that influence happiness both from within as well as outside a person. Inside influences would involve the brain and the biology of the individual. Outside factors would include relationships and social identity. Research has shown that

A large portion of our lives are spent in one particular state of consciousness. This state is sleep‚ it is critical to our health and daily functioning. With my roommate coming home at various hours of the night‚ my sleep is disrupted impacting my health and daily functioning. In a typical night’s sleep a person passes through five stages. These stages progress in a cycle from stage 1 to rapid eye movement‚ also known as REM. I will describe each of the five cycles and how they are critical to health

REM sleep is the process of phases in which there is low physical movement‚ and the propensity of the sleeper to dream vividly. The phase is also known as paradoxical sleep and sometimes desynchronized sleep because of the physiological similarities to being awake‚ including rapid‚ low-voltage desynchronized brain waves. The right and left hemispheres of the brain are more coherent in REM sleep‚ especially during lucid dreams. Two other neurotransmitters seem to promote wakefulness‚ diminish during

Stage 1 sleep Stage 1 sleep is experienced as falling to sleep and is a transition stage between wake and sleep. It usually lasts between 1 and 5 minutes and occupies approximately 2-5 % of a normal night of sleep. This stage is dramatically increased in some insomnia (restless legs) and disorders that produce frequent arousals such as apnea . Stage 2 sleep Stage 2 sleep follows stage 1 sleep and is the baseline of sleep. This stage is part of the 90 minute cycle and occupies approximately 45-60%

Maisarah Mahusin Block 5 5/4/2015 Dement & Kleitman experiment is to find out the relation of eye movements during sleep to dream activity. There are three hypotheses that they wanted to test in this study‚ first there will be a significant association between REM and dreaming‚ second there will be a significant positive correlation between the estimate of time spent dreaming and the length of eye movement

Stages of Sleep The EEG (Electroencephalogram)of a waking person is clearly different than that of a sleeping person. The difference in EEG patterns that occur during sleep has made it possible to divide sleep into five different stages. Stage One We experience stage one of sleep when we are half asleep and half awake; our eyelids feel heavy‚ we feel groggy and suddenly without notice we fall asleep. Stage one counts for more or less 5% our total sleep during the night. Stage

"The foundation for much of what we know about sleep was gathered approximately 40 years ago by researcher‚ Michel Jouvet. This French scientist studied the effects of gross brain lesions and brain transections on sleep behavior and related phenomena. It was Jouvet who first suggested that a brainstem region is responsible for the initiation of events that result in the stage of sleep called REM sleep. REM sleep is a stage associated with rapid eye movements‚ a high degree of brain wave activity
