  • circadian
  • Many of the physiological processes that recur in humans about every 24 hours (with circadian rhythm ) have been known for centuries. (thefreedictionary.com)
  • Biochemical analyses of urine, blood enzymes, and plasma serum also have demonstrated circadian rhythms. (thefreedictionary.com)
  • circadian rhythm the regular recurrence in cycles of about 24 hours from one point to another, such as certain biological activities that do this regardless of long periods of darkness or other changes in environmental conditions. (thefreedictionary.com)
  • There is a world-wide crisis in sleep quality where in my opinion, wireless technologies have insidiously infiltrated every bedroom in every urban area on the planet resulting in crippling effect on circadian rhythm, sleep quality and overall health. (pr.com)
  • brain
  • The present approaches complement and solve some of the incertitudes when the classical brain broad rhythm analysis is applied. (biomedcentral.com)
  • During the day, the brain receives and processes a huge amount of various information, and its memorization is carried out in the delta phase. (perfecthealthus.com)
  • Although spindles have been the most thoroughly studied of these rhythms, in experimental animals as well as humans, with electrophysiological, metabolic, brain imaging and pathology, molecular genetic and computational modeling methods, their nature is still elusive. (intechopen.com)
  • slow-wave
  • In her study, Van Cauter demonstrated lack of slow-wave or Delta-rhythm sleep affects metabolism and appetite to such an extent that previously healthy 20 year olds' blood sugar and insulin parameters can reach pre-diabetic levels in as little as 4 nights. (pr.com)
  • Component
  • Loss of tonic neuromodulatory excitation, mediated by nicotinic acetylcholine or serotonin (5HT3A) receptors, of 5HT3-immunopositive interneurons caused an increase in amplitude and slowing of the delta rhythm until each period became the 'wave' component of the spike and wave discharge. (yale.edu)
  • In contrast, the 'spike' component of the spike and wave discharge originated from a relative failure of fast inhibition in layers 2/3-switching pyramidal cell action potential outputs from single, sparse spiking during delta rhythms to brief, intense burst spiking, phase-locked to the field spike. (yale.edu)
  • study
  • Results from this study suggest that loss of median SEP, prolongation of wave III in AEP and flash-VEP as well as theta or delta rhythms in EEG are associated with poor outcome from neurological early rehabilitation. (biomedcentral.com)
  • typical
  • It proves that such peculiarity of localization of changes in the specifi c weight of the major rhythms of EEG may form typical zones of headache attack, accompanying migraines with predominance in the temporal-frontal areas. (uvnpn.com.ua)
  • phase
  • Here we show that performance changes related to different levels of expectancy originate in dynamic modulation of delta oscillation phase. (jneurosci.org)
  • Reaction times correlated with the phase of the delta band oscillation at target onset. (jneurosci.org)
  • The fastest reactions occurred during the delta phase that most commonly coincided with the target event in the high expectancy conditions. (jneurosci.org)
  • This specific phase relationship coupled the acquisition phases of the two sensorimotor rhythms, inhalation and whisker protraction. (jneurosci.org)
  • Why is the delta phase important in the process of night rest? (perfecthealthus.com)
  • different
  • Correlational analysis showed a lower pattern of correlation between different frequencies in children than in young adults, suggesting a certain asynchrony in the maturation of different rhythms. (biomedcentral.com)
  • results
  • Our results suggest that sniffing and whisking may be under the control of interdependent rhythm generators that dynamically coordinate active acquisition of olfactory and somatosensory information. (jneurosci.org)
  • similar
  • The rhythm of heart sounds which resembles that in the fetus in that both sounds are similar in character and intensity. (wordinfo.info)
