Slow oscillation circuit of the intergeniculate leaflet
The slow oscillation circuit of the intergeniculate leaflet seems to constitute a natural basic rhythm of the neuronal mechanism of mammalian biological clock. The results of studies conducted so far indicate that photic information flowing from ganglion cells of the retina is necessary for its generation.

Membrane resonance enables stable and robust gamma oscillations [PDF]
Neuronal mechanisms underlying beta/gamma oscillations (20-80 Hz) are not completely understood. Here, we show that in vivo beta/gamma oscillations in the cat visual cortex sometimes exhibit remarkably stable frequency even when inputs fluctuate ...

Fractional dynamics of globally slow transcription and its impact on deterministic genetic oscillation. [PDF]
In dynamical systems theory, a system which can be described by differential equations is called a continuous dynamical system. In studies on genetic oscillation, most deterministic models at early stage are usually built on ordinary differential ...

Human Gamma Oscillations during Slow Wave Sleep
Los potenciales de campo local neocorticales han demostrado que las oscilaciones gamma ocurren espontáneamente durante el sueño de onda lenta (SWS). A nivel de EEG macroscópico en el cerebro humano, no se informaron evidencias hasta el momento. En este estudio, mediante el uso de registros simultáneos de EEG del cuero cabelludo e intracraneal en 20 ...

The role and implications of mammalian cellular circadian entrainment
At their most fundamental level, mammalian circadian rhythms occur inside every individual cell. To tell the correct time, cells must align (or ‘entrain’) their circadian rhythm to the external environment. In this review, we highlight how cells entrain to the major circadian cues of light, feeding and temperature, and the implications this has for our

Bursting Oscillations in Shimizu-Morioka System with Slow-Varying Periodic Excitation
The coupling effect of two different frequency scales between the exciting frequency and the natural frequency of the Shimizu-Morioka system with slow-varying periodic excitation is investigated.

Slow Oscillation in Non-Lemniscal Auditory Thalamus [PDF]
In the present study, we investigated the oscillatory behavior of the auditory thalamic neurons throughin vivointracellular and extracellular recordings in anesthetized guinea pigs. Repeated acoustic stimulus and cortical electrical stimulation were applied to examine their modulatory effects on the thalamic oscillation.

Disordered but rhythmic—the role of intrinsic protein disorder in eukaryotic circadian timing
Unstructured domains known as intrinsically disordered regions (IDRs) are present in nearly every part of the eukaryotic core circadian oscillator. IDRs enable many diverse inter‐ and intramolecular interactions that support clock function. IDR conformations are highly tunable by post‐translational modifications and environmental conditions, which ...

We study the real-time dynamics of a quantum Ising chain driven periodically by instantaneous quenches of the transverse field (the transverse field varying as rectangular wave symmetric about zero).

Time after time – circadian clocks through the lens of oscillator theory
Oscillator theory bridges physics and circadian biology. Damped oscillators require external drivers, while limit cycles emerge from delayed feedback and nonlinearities. Coupling enables tissue‐level coherence, and entrainment aligns internal clocks with environmental cues.
