Updated: January 30, 2024

Cataplexy is a sudden, brief loss of voluntary muscle tone triggered by strong emotions such as laughter. The condition is most commonly associated with narcolepsy, a sleep disorder that is thought to affect between 135,000 and 200,000 people in the United States. Cataplexy occurs during waking hours.

What occurs when a drug user requires more and more of a given drug in order to experience the same effects of the drug?

Tolerance happens when a person no longer responds to a drug in the way they did at first. So it takes a higher dose of the drug to achieve the same effect as when the person first used it. This is why people with substance use disorders use more and more of a drug to get the “high” they seek.

What play a role in controlling slow-wave sleep?

As already mentioned, the hypothalamus contains the SCN—the biological clock of the body —in addition to other nuclei that, in conjunction with the thalamus, regulate slow-wave sleep. The pons is important for regulating rapid eye movement (REM) sleep (National Institutes of Health, n.d.).

Is most effective in individuals who are very open to the power of suggestion?

For individuals who are especially open to the power of suggestion, hypnosis can prove to be a very effective technique, and brain imaging studies have demonstrated that hypnotic states are associated with global changes in brain functioning (Del Casale et al., 2012; Guldenmund, Vanhaudenhuyse, Boly, Laureys, & Soddu, ...

What happens in slow-wave sleep?

Slow-wave sleep (SWS) refers to phase 3 sleep, which is the deepest phase of non-rapid eye movement (NREM) sleep, and is characterized by delta waves (measured by EEG). Dreaming and sleepwalking can occur during SWS. SWS is thought to be important for memory consolidation.

A circadian rhythm (/sərˈkeɪdiən/), or circadian cycle, is a natural, internal process that regulates the sleep–wake cycle and repeats roughly every 24 hours.

Is the hormone that is produced in the brain and is secreted to increase sleepiness quizlet?

Melatonin is a hormone secreted by the enigmatic pineal gland in response to darkness, hence the name hormone of darkness.

Which theory suggests that dreaming should be seen as an ancient biological defense mechanism?

In particular, the “threat simulation theory” suggests that dreaming should be seen as an ancient biological defence mechanism that provided an evolutionary advantage because of its capacity to repeatedly simulate potential threatening events – enhancing the neuro-cognitive mechanisms required for efficient threat ...

Which of the following is characterized by delta waves?

Characterized by delta waves, the slowest and highest-amplitude brain waves during sleep . These two stages are often referred to as delta sleep.

Which of the following correctly names the sleep disorder in which a person stops breathing numerous times throughout the night?

What is sleep apnea ? Sleep apnea is a potentially serious sleep disorder that occurs when a person’s breathing is interrupted during sleep. People with untreated sleep apnea stop breathing repeatedly during their sleep. There are two types of sleep apnea: obstructive and central.

What is characterized by high levels of sensory awareness thought and behavior?

Wakefulness is characterized by high levels of sensory awareness, thought, and behavior.

What does the social cognitive theory of hypnosis suggest?

Social-cognitive theory of hypnosis argues that the experience of effortlessness in hypnosis results from participant’s motivated tendencies to interpret hypnotic suggestions as not requiring active planning and effort (i.e. the experience of effortlessness stems from an attributional error).

What content of a dream refers to the true meaning of the dream?

Freud believed that the content of dreams is related to wish fulfillment and suggested that dreams have two types of content: manifest content and latent content. The manifest content is the actual literal subject matter of the dream while the latent content is the underlying meaning of these symbols.

How does the lack of sleep affect your mood?

Studies show people who are sleep deprived report increases in negative moods (anger, frustration, irritability, sadness) and decreases in positive moods . And sleeplessness is often a symptom of mood disorders, such as depression and anxiety.

Which sleep disorder is associated with a deficiency of hypocretin?

Narcolepsy with cataplexy (NC) is a sleep disorder caused by the loss of the hypothalamic neurons producing hypocretin. The clinical hallmarks of the disease are excessive daytime sleepiness, cataplexy, other rapid eye movement (REM) sleep phenomena, and a fragmented wake-sleep cycle.

Why does lack of sleep make me angry?

Sleep experts believe that the correlation between lack of sleep and increased impatience is due to the part of our brains that deals with our instinctive and primal emotions . This is known as the limbic system. Within the limbic system, there are two small areas collectively known as the amygdala.

How does lack of sleep affect work performance?

The Sleep-deprived Employee

Sleep deprivation negatively affects work performance—productivity and quality—and working relationships. Without adequate sleep, employees have more difficulty concentrating, learning , and communicating. Memory lapses increase. Problem-solving abilities decline.

What is a narcoleptic episode?

People with narcolepsy often experience a temporary inability to move or speak while falling asleep or upon waking . These episodes are usually brief — lasting a few seconds or minutes — but can be frightening.

What is another name for slow-wave sleep?

SWS, or delta sleep , follows stage 2 sleep and is characterized by polymorphic, semirhythmic delta waves accounting for at least 20% of the EEG activity.

What factors can change circadian rhythms?

What are the 4 biological rhythms?

What does the circadian rhythm control?

Circadian rhythm is the 24-hour internal clock in our brain that regulates cycles of alertness and sleepiness by responding to light changes in our environment.

Is the hormone that is produced in the brain and is secreted to increase sleepiness?

Melatonin secreted by the pineal gland is an important part of the body’s circadian timing system and can synchronise daily rhythms (see the articles on jet lag and circadian rhythm sleep disorders). Melatonin is secreted more when it is dark which explains melatonin’s role in sleep.

Why is REM sleep also known as paradoxical sleep?

The REM phase is also known as paradoxical sleep (PS) and sometimes desynchronized sleep, because of physiological similarities to waking states including rapid, low-voltage desynchronized brain waves .

Which sleep disorder is characterized by the inability of air to move in and out of a person’s nose or mouth even though the body tries to breathe?

Obstructive sleep apnea occurs when air can’t flow into or out of your nose or mouth – even when you’re making an effort to breathe.

Is the theory of dreaming that suggests dreams are caused by biological processes?

Sleep helps the brain perform a number of activities including cleaning up the brain and consolidating memories from the previous day. 2 Activation-synthesis theory suggests that the physiological processes that take place as we sleep are the cause of dreams.

What are delta waves in psychology?

A delta wave is a type of high amplitude brain wave found in humans that is associated with deep sleep . Delta waves have a frequency from one to three hertz (Hz) and are measured using an electroencephalogram (EEG). 1.

What does listening to delta waves do?

Listening to binaural beats consistently and regularly before going to sleep can train your brain to enter the wavelength you are targeting, in the case of sleep, Theta or Delta waves. Research has shown that listening to low-frequency tones can trigger a slowdown in brain activity that will aid relaxation and sleep .
