Chronobiologists have seen this as a model mammalian system to study the physiological and neurobiological underpinnings of a biologically relevant circadian complex. However, observations of nursing in wild rabbits, together with studies of nursing in domestic breeds allowed free access to their young in laboratory settings, suggest that the rabbit’s pattern of daily nursing visits resembles an hourglass rather than a circadian process, well suited to the sudden starts and stops of natural nursing cycles. We consider whether there might be other such cases in the literature, including in human chronobiology, in which failing to consider the organism’s natural, evolved daily patterns of behaviour and prematurely studying these under artificially imposed laboratory time schedules might have also led to such patterns being erroneously considered circadian.","PeriodicalId":306238,"journal":{"name":"Circadian Rhythm - New Insights Into the Physiological and Pathological Implications [Working Title]","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-02-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134080157","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We conducted screening studies of representative samples of men aged 25–64 years. The general examination was carried out according to the standard methods included in the WHO MONICA-Psychosocial Program (MOPSY). Carriers of the C/T genotype of the CLOCK gene more often than others reported having “satisfactory” or “poor” sleep. Carriers of the C/T genotype of the ARNTL gene were more likely to experience anxiety dreams, and they woke up exhausted. Carriers of the A/A genotype of the PER2 gene were more likely to wake up two or more times per night, a total of four to seven times per week. In the population, C/T and T/T genotypes of the NPAS2 gene were significantly more common in individuals with 7-hour sleep. Genotype 4/6 of the DRD4 gene and genotype 9/9 of the DAT gene were significantly associated with sleep disturbances. Carriers of the heterozygous A/G genotype of the TNF-α-308 gene, compared with carriers of all other genotypes, more often rated sleep as “satisfactory” (30%) than “good.”","PeriodicalId":306238,"journal":{"name":"Circadian Rhythm - New Insights Into the Physiological and Pathological Implications [Working Title]","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-02-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128166752","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Circadian Sensation and Visual Perception 昼夜节律感觉和视觉知觉

{"title":"Circadian Sensation and Visual Perception","authors":"Michael Jackson Oliveira de Andrade","doi":"10.5772/intechopen.100591","DOIUrl":"https://doi.org/10.5772/intechopen.100591","url":null,"abstract":"The physiology of living beings presents oscillations that are known as biological rhythms. The most studied rhythm is called circadian (circa = circa, dies = day), because it varies with a period close to 24h. Most functions of the body have circadian variations, one can mention, for example, metabolism, body temperature, the activity of the nervous system, secretion of hormones such as melatonin and cortisol. Circadian rhythms were also found in human behavior, for example: in sensory activity, motor activity, reaction time, visual perception, auditory perception, time perception, attention, memory, arithmetic calculus, and executive functions. The present work reviews the visual path that participates in the synchronization of circadian rhythms, as well as the evidence that exists about the presence of circadian rhythms in the sensation and visual perception of the human being.","PeriodicalId":306238,"journal":{"name":"Circadian Rhythm - New Insights Into the Physiological and Pathological Implications [Working Title]","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-12-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116001074","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
