Circadian rhythms are controlled by the hypothalamus in humans. Circadian rhythm refers to the body's biological clock that determines when a person should sleep, and it controls a variety of other body processes, as well.

What are the difference between human brain and the sheep brain?
The human brain is larger. The positioning of the hind brain is different, due to the erect position of humans. Convolutions are increased in humans (increases surface area). The sheep's brain has a smaller cerebellum (lesser motor control/less complex learned motor behaviors). There is a larger pineal gland in sheep (related to circadian rhythms/seasonal reproduction).
Why psychologists are interested in studying biological rhythms?
Psychologists are interested in studying biological rhythms because these rhythms play a crucial role in human behavior and cognition. Biological rhythms, such as the sleep-wake cycle or circadian rhythms, influence our sleep patterns, mood, and cognitive performance. Understanding how these rhythms impact human functioning can help psychologists develop interventions and treatments for sleep disorders, mood disorders, and other conditions related to disruptions in biological rhythms. Additionally, studying biological rhythms can provide insights into the impact of lifestyle factors, like shift work or jet lag, on human functioning.
What does light therapy do?
The exact mechanisms by which the treatment works are not known, but the bright light employed in light therapy may act to readjust the body's circadian rhythms, or internal clock. During light therapy, you sit or work near a device called a light therapy box. The box gives off bright light that is like a natural light. This treatment is considered to affect certain chemicals in our brain linked to relieving SAD, mood disorders, other types of depression, sleep disorders, stress and even various skin problems.
What houses the mechanisms that most often interact with substances that cross the blood brain barrier?
forebrain
What is an fact about the medulla oblongata?
It has the mechanisms for controlling our body's reflex activities such as coughing and vomiting
What brain structure is most responsible for monitoring circadian rhythms?
Suprachiasmatic nucleus
What part of the brain that secretes melatonin to help regulate circadian rhythms?
Suprachiasmatic nucleus
What are the anatomical structures responsible for circadian rhythms?
Mostly the suprachiasmatic nucleus (SCN) in the brain. The pineal gland is also involved.
Cycles in the nervous system?
i assume you mean night - day cycles called circadian rhythms. these are variations in the brain's activity depending on the time of the day.
The hypothalamus is like your brains inner thermastat ..?
The hypothalamus is located below the thalamus and above the brain stem. Its functions are controlling body temperature, hunger, thirst, sleep, and circadian rhythms.
What brain nucleus is the body's biological clock?
Circadian clock gene The Clock gene not only controls the body's circadian rhythms, including sleep and wakefulness, body temperature, hormone levels, blood pressure and heart activity, it may also be a key regulator of the brain's reward system.
What are circadian rhythms and how are they of adaptive value?
Circadian rhythms are important in determining the sleeping and feeding patterns of all animals, including human beings. There are clear patterns of core body temperature, brain wave activity, hormone production, cell regeneration and other biological activities linked to this daily cycle. In addition, photoperiodism, the physiological reaction of organisms to the length of day or night, is vital to both plants and animals, and the circadian system plays a role in the measurement and interpretation of day length.
Why is morning depression hardest time of the day?
Depression has been demonstrated to interfere with Circadian rhythms. This means the brain is doing the wrong things at the wrong time. Further, lack of sleep from the night before can compound matters.
Circadian rhythm is an important concept in psychology What is it?
Circadian Rhythm is a 24 hour cycle in the physiological, behavioral or biochemical processes of living beings, including humans, animals, plants and micro-organisms. Although circadian rhythms are endogenous to the living being, they are affected by external triggers, such as light. To classify a rhythm as circadian, it should persist in the absence of external cues, should persist over a range of temperatures, and should be possible to adjust to local time. The impact of circadian rhythm can be seen in the patterns of a variety of activities such as eating, sleeping, brain activity, temperature, hormone production and cell regeneration. The importance of circadian rhythm in psychology stems from the fact that disturbances in this rhythm can lead to disorders such as Delayed Sleep Phase Syndrome (DSPS), fatigue, disorientation and insomnia. Other disorders such as bipolar disorder and sleep disorders are associated with irregular function of the circadian rhythm.

What produce melatonin?
The pineal gland in the brain produces melatonin at night during sleep. Seratonin is produced during the day, These two hormones maintain the Circadian Rhythms or our '24 hr' clock. If the body clock is upset, as in jet lag, sleeping is difficult.
Why do you need to sleep at night?
Your brain is programmed for it through your circadian cycles.
