EEG Delta Activity During Human Sleep as a Damped Ultradian Rhythm
Psychophysiology, 1973ABSTRACTEEG delta activity during human sleep has a rhythmic pattern resembling a damped sinusoid with a period of about 100 min. Although the REM episodes coincide with the troughs of the delta cycle, the two rhythms are semi‐independent.

Circadian rhythms in humans’ delta sleep electroencephalogram
Neuroscience Letters, 2003Eight healthy young male volunteers entered a 20-40 min ultrashort sleep-wake schedule for 78 h in the time-isolation facility. Rectal temperature was continuously recorded. Sleep electroencephalograms (EEGs) obtained during 20 min nap trials were stored in the computer and later analyzed by fast Fourier transform.

Effect of rhythm-based prediction on medial olivocochlear reflex and delta oscillations
The Journal of the Acoustical Society of America, 2021The medial olivocochlear reflex (MOCR) is an efferent feedback activated by acoustic stimulation. Our previous studies showed that a preceding sound expedites MOCR, which suggests that temporal expectation about the timing of stimulus occurrence can modulate MOCR.

Topographical distribution of delta rhythms during sleep: Evolution with age
Electroencephalography and Clinical Neurophysiology, 1981This study concerns the evolution of slow EEG activities (delta rhythms) and their topographical distribution during 31 night sleep records of 27 control subjects whose ages ranged from 1 month to 27 years. A system of data processing allows the representation of continuous changes in 8 derivations of the power of 0.5--4.5 c/sec waves.

Functional MRI Correlates of Resting-State Temporal Theta and Delta EEG Rhythms
Journal of Clinical Neurophysiology, 2017Purpose: The EEG rhythms demonstrate changes in frequency and power with spontaneous changes in behavioral state that do not have well-understood metabolic correlates within the brain. To investigate this question and compare the temporal lobe theta and delta rhythms, resting-state functional MRI was obtained with simultaneous ...

System for studying the topography of delta rhythm during sleep: Further development
Electroencephalography and Clinical Neurophysiology, 1980A hybrid system for treatment of all-night sleep EEG records is described, which leads to the representation of sleep cycles by the continuous variation of the amplitude in a given frequency band. This system constitutes the development of a previous purely analogic one.

Acoustic-driven delta rhythms as prosodic markers
Language, Cognition and Neuroscience, 2016ABSTRACTOscillation-based models of speech perception postulate a cortical computation principle by which decoding is performed within a time-varying window structure, synchronised with the input on multiple time scales. The windows are generated by a segmentation process, implemented by a cascade of oscillators.

System for studying the delta rhythm during sleep and its topographical amplitude distribution
Electroencephalography and Clinical Neurophysiology, 1979An analogue system of processing all-night sleep EEG records which leads to the representation of sleep cycles by the continuous variation of the amplitude parameter in a given frequency band is described. The curves obtained are analogous to those resulting from more sophisticated computerized analyses.

Delta opioid inhibition of light-induced phase advances in hamster circadian activity rhythms
Brain Research, 2002A master neuronal pacemaker located within the suprachiasmatic nucleus in the ventral hypothalamus generates circadian activity rhythms in hamsters. The circadian pacemaker receives afferent input from many brain regions, one of which is the intergeniculate leaflet of the thalamus. This thalamic input to the suprachiasmatic nucleus in hamsters contains
