NREM Stage 1 (N1 – light sleep, somnolence, drowsy sleep – 5–10% of total sleep in adults): This is a stage of sleep that usually occurs between sleep and wakefulness, and sometimes occurs between periods of deeper sleep and periods of REM. The muscles are active, and the eyes roll slowly, opening and closing moderately.
Neuromelanin gives specific brain sections, such as the substantia nigra or the locus coeruleus, distinct color. It is a type of melanin and similar to other forms of peripheral melanin. It is insoluble in organic compounds, and can be labeled by silver staining. It is called neuromelanin because of its function and the color change that ...
In vertebrates, melatonin is produced in darkness, thus usually at night, by the pineal gland, a small endocrine gland [73] located in the center of the brain but outside the blood–brain barrier. Light/dark information reaches the suprachiasmatic nuclei from retinal photosensitive ganglion cells of the eyes [74] [75] rather than the melatonin ...
Improvement to cognitive performance caused by exercise could last for 24 hours, a new study shows. Scientists also linked getting 6 or more hours of sleep to better memory test scores the next day.
Light therapy can improve sleep quality, improve sleep efficiency, and extend sleep duration by helping to establish and consolidate regular sleep-wake cycles. Light therapy is a natural, simple, low-cost treatment that does not lead to residual effects or tolerance. Adverse reactions include headaches, eye fatigue, and even mania. [187]
The suprachiasmatic nucleus or nuclei (SCN) is a small region of the brain in the hypothalamus, situated directly above the optic chiasm. It is responsible for regulating sleep cycles in animals. [ 1 ] [ 2 ] Reception of light inputs from photosensitive retinal ganglion cells allow it to coordinate the subordinate cellular clocks of the body ...
The substantia nigra (SN) is a basal ganglia structure located in the midbrain that plays an important role in reward and movement. Substantia nigra is Latin for "black substance", reflecting the fact that parts of the substantia nigra appear darker than neighboring areas due to high levels of neuromelanin in dopaminergic neurons.
