SCN
The SCN is found within this specific Brain region.
What is found in the Hypothalamus?
This gland is located in the brain, and it produces and secretes Melatonin.
What is the Pineal gland?
This particular biological rhythm lasts about 24 hours and is linked with the rotation of the Earth.
What is Circadian Rhythm?
Postural tension in the skeletal muscular system is completely eliminated during this stage of sleep.
What is REM sleep?
Common in those who travel often, this condition can decrease circadian health.
What is Jet lag?
This visual pathway is in charge of transmitting light information from the retina to the SCN.
What is the Retinohypothalamic pathway?
This particular amino acid helps maintain healthy melatonin levels.
What is tryptophan?
Without environmental cues, this particular biological rhythm in mammals usually lasts between 330 and 400 days.
What is Circannual rhythm?
By the time humans reach adulthood, they spend about 20% of their total sleep time in this particular sleep stage.
What is REM sleep?
Flight crews with constant circadian disruption are correlated with a decrease in volume in this particular brain lobe.
What is the Temporal lobe?
In Alzheimer's disease, the SCN shows a reduction in volume and number of cells containing this neuropeptide.
What is Vasopressin?
Melatonin is synthesized from this precursor neurotransmitter.
What is Serotonin?
Environmental cues that synchronize the body's internal clocks go by this scientific name.
What are Zeitgebers?
Cerebral blood flow is reduced during this period of sleep.
What is NREM sleep?
What is Fatty Liver Disease?
The specific retinal ganglion cells that contain melanopsin and project to the SCN
What are ipRGCs?
Melatonin binds to MT1 and MT2 to promote sleep in this particular thalamic area.
What is the Paraventricular thalamus (PVT)?
Factors like treadmill running and social interactions are considered this type of zeitgeber.
What is a nonphotic zeitgeber?
This hormone is secreted at high quantities during NREM sleep, but drops to low levels during REM sleep.
What is growth hormone?
In the flight crew study, the decreased volume in the specific brain lobe found was negatively correlated with the levels of this particular hormone.
What is Cortisol?
In the cellular molecular clock pathway, this protein works with CLOCK to promote transcription of Per and Cry genes.
What is BMAL1?
This enzyme is responsible for the final conversion of N-acetylserotonin into Melatonin.
What is HIOMT?
Along with exercises and meals, this nonphotic zeitgeber is a powerful opioid drug capable of altering our biological clock.
What is Morphine?
While maintained during NREM sleep, this physiological process associated with body heat is impaired during REM sleep.
What is Thermoregulation?
What is Reaction time?
