Unit 4 - AOS 1 (Sleep) Flashcards
Define sleep
A regularly occurring ASC that typically occurs naturally, and is primarily characterised by partial or total suspension of conscious awareness
What is an EEG?
A method of studying brain waves produced during sleep
An EEG is used to detect amplify and record the electrical activity of brainwaves through electrodes manually placed at various points on the scalp
What is an EMG?
A method of studying the electrical activity of muscles produced during sleep
An EMG is used to detect amplify and record the electrical activity of the muscles through attaching electrodes to the skin above the relevant muscles, particularly the jaw
What is an EOG?
A method of measuring eye movements or positions during sleep
An EOG is used to detect amplify and record the electrical activity in eye muscles that control eye movement
What are the different types of brain waves?
Baiter Alpha Theta Delta
What is a sleep diary?
A log used to self record sleep and waking time activities over a period of time, usually one week or more
What is video monitoring?
Were labs are fitted with one or more videocameras to record externally observable physiological responses through a sleep episode
What are biological rhythms?
Cyclic changes in bodily functions or activities that repeat themselves through time in the same order
What is a biological clock?
An innate timing mechanism that regulates the cycle of a biological rhythm
What is a circadian rhythm and what is an example?
A biological rhythms that involves changes in bodily functions or activities that occur as part of a cycle, with the duration of about 24 hours
The sleep wake cycle is a circadian rhythm
What is an ultradian rhythm?
A biological rhythms that involves physiological, psychological or behavioural changes that occur as part of a cycle shorter than 24 hours
What is suprachiasmatic Nucleus?
The master biological clock that regulates the timing and activity of the sleep wake cycle
What is melatonin?
A hormone that is involved in the initiation of sleep, and in the regulation of the sleep wake cycle
