Journal ArticleDOI
Daily rhythm of serum melatonin in patients with dementia of the degenerate type
TL;DR: The results suggest that the probability of absent melatonin rhythm is higher in demented patients compared with subjects without dementia, however, a lack of melatonin Rhythm is not always associated with symptomatic rhythm disorders.
Journal ArticleDOI
Entladungsmuster pinealer Neurone der Regenbogenforelle (Salmo irideus) bei Belichtung des Zwischenhirns
TL;DR: The Maxima der Spektralsensitivitat der einzelnen Pinealneurone variieren zwischen 500 and 533 mμ as mentioned in this paper.
Journal ArticleDOI
Daily rhythm of serum melatonin levels and effect of light exposure in patients with dementia of the Alzheimer's type.
TL;DR: The high levels of melatonin in the daytime associated with a lack of response to light exposure in AD patients may be due to the neurodegenerative process of this disease.
Journal ArticleDOI
Photoreception in pineal organs of larval and adult lampreys, Lampetra japonica
Satoshi Tamotsu,Yukitomo Morita +1 more
TL;DR: The intracellular response to light of the larval pineal was a hyperpolarization, showing fundamentally the same pattern as that of the adult pineal, and a change of visual pigment in the pineal during metamorphosis is suggested.
Journal ArticleDOI
Pineal-dependent locomotor activity of lamprey, Lampetra japonica, measured in relation to LD cycle and circadian rhythmicity
TL;DR: The results indicate that the pineal organ of the lamprey is a photoreceptive organ responsible for synchronizing locomotor activity to LD cycle, and appears to function as an oscillator, or as one of the oscillators, for the circadian locomotor rhythm of lampreys.
