Abstract:
The endogenous electrical signals play an important role in information processes occurring in living systems. They are found in living beings of different evolutionary levels from prokaryotes to multicellular eukaryotes. We hypothesized that the presence and variety of endogenous oscillators in individual organisms are connected with the way they survive, i.e. totally dependent on the community or partially independent of it. To test the hypothesis, we recorded electrical activity from individual cells and their communities in experiments with the earliest evolutionary beings, prokaryotes: cy

Abstract:
Phase resetting curves (PRCs) are phenomenological and quantitative tools that tabulate the transient changes in the firing period of endogenous neural oscillators as a result of external stimuli, for example, presynaptic inputs. A brief current perturbation can produce either a delay (positive phase resetting) or an advance (negative phase resetting) of the subsequent spike, depending on the timing of the stimulus. We showed that any planar neural oscillator has two remarkable points, which we called neutral points, where brief current perturbations produce no phase resetting and where the PR

Abstract:
per° Mutants of Drosophila melanogaster which are exposed to light-dark cycles (LD) with different Zeitgeber period (T) have a limited range of entrainment. Entrained flies show a characteristic phase relationship of activity to the LD which depends on the period of the driving cycle as expected by oscillator theory. Both facts are taken as evidence that per° possesses endogenous oscillators and that the per gene product is not concerned with central clock structures but rather might be responsible for the mutual coupling between the individual oscillators in a multioscillatory system controll

Abstract:
Nonlinear ionic interactions at the nerve cell membrane can account for oscillating membrane potentials and the generation of periodic neuronal impulse activity. In combination with noise, external modulation of the endogenous oscillations allows for continuous transitions between a variety of impulse patterns. Such "noisy oscillators" afford, thereby, an important mechanism of neuronal encoding as is demonstrated here with experimental data from peripheral cold receptors and corresponding computer simulations.

Abstract:
The circadian system is responsible for the temporal organisation of physiological functions which, in part, involves daily cycles of hormonal activity. In this review, we analyse the interplay between the circadian and endocrine systems in fishes. We first describe the current model of fish circadian system organisation and the basis of the molecular clockwork that enables different tissues to act as internal pacemakers. This system consists of a net of central and peripherally located oscillators and can be synchronised by the light–darkness and feeding–fasting cycles. We then focus on two c

Abstract:
We study the properties of a network consisting of two model neurons that are coupled by reciprocal inhibition. The study was motivated by data from a pair of cells in the crustacean stomatogastric ganglion. One of the model neurons is an endogenous burster; the other is excitable but not bursting in the absence of phasic input. We show that the presence of a hyperpolarization activated inward current (ih) in the excitable neuron allows these neurons to fire in integer subharmonics, with the excitable cell firing once for every N ≥ 1 bursts of the oscillator. The value of N depends on the amou

Abstract:
Megachiroptera inhabit the Old World tropics and most are seasonal breeders having defined times of testis growth, mating and parturition. In Pteropus scapulatus, the little red flying fox, the robust rhythm of testis cycles is resistant to modification by photoperiod. P. poliocephalus, the greyheaded flying fox, can be manipulated by photoperiod but responds slowly and incompletely. Most mammals live in the tropics, many in seasonally harsh climates, and many breed seasonally. However, few long-lived tropical mammals have been investigated for photoperiodic entrainment of annual reproductive

Abstract:
Daily rhythms of physiology and behaviour are governed by an endogenous timekeeping mechanism (a circadian ‘clock’). The alternation of environmental light and darkness synchronizes (entrains) these rhythms to the natural day–night cycle, and underlying mechanisms have been investigated using singly housed animals in the laboratory. But, most species ordinarily would not live out their lives in such seclusion; in their natural habitats, they interact with other individuals, and some live in colonies with highly developed social structures requiring temporal synchronization.

Abstract:
The plant circadian clock has a pervasive influence on many aspects of plant biology and is proposed to function as a developmental manager. To do so, the circadian oscillator needs to be able to integrate a multiplicity of environmental signals and coordinate an extensive and diverse repertoire of endogenous rhythms accordingly. Recent studies on tissue-specific characteristics and spatial structure of the plant circadian clock suggest that such plasticity may be achieved through the function of distinct oscillators, which sense the environment locally and are then coordinated across the plan

Abstract:
Cascading failures abound in complex systems and the Bak–Tang–Weisenfeld (BTW) sandpile model provides a theoretical underpinning for their analysis. Yet, it does not account for the possibility of nodes having oscillatory dynamics, such as in power grids and brain networks. Here, we consider a network of Kuramoto oscillators upon which the BTW model is unfolding, enabling us to study how the feedback between the oscillatory and cascading dynamics can lead to new emergent behaviors. We assume that the more out-of-sync a node is with its neighbors, the more vulnerable it is and lower its load-c

Noise is ubiquitous, stemming from the surrounding environment or arising from the inherent stochasticity of the system under consideration. Its presence may qualitatively change the behavior of a physical system, possibly leading to surprising and unexpected phenomena, and, as such, it should be accommodated for in realistic models. In this work, I present several models, that bear interest in neuroscience, in which noise plays a role of paramount importance.

Abstract:
The 24-hour sleep–wake cycle is generated by two oscillatory processes: an endogenous hypothalamic circadian pacemaker and a sleep- and wake-dependent homeostat. These processes combine to maintain a consolidated bout of sleep at night and relatively stable waking function across the day. They also combine to determine ‘diurnal preference’—whether one is a ‘lark’ or an ‘owl’—a reflection of the phase relationship between the circadian and homeostatic processes. These processes are affected directly by light, either through resetting of the circadian pacemaker or its direct alerting effects. Sl

Abstract The aim of this chapter is to begin applying a rational modelling approach to human memory for sequential order.

Here we argue that very general features of human sequential behavior-features that are observed in many different domains of human action and thought-can be understood as resul

Circadian organization comprises both hierarchical and distributed pacemakers, as well as peripheral oscillators that are coordinated by the hypothalamic suprachiasmatic nuclei (SCN). Among the peripheral tissues that are coordinated by the SCN is the gastrointestinal system via the sympathetic nervous system. At each level of gastrointestinal function, circadian clocks regulate the homeostatic functions of consuming, breaking down, digesting and absorbing nutrients. This system contains a semi-independent circadian clock capable of producing endogenously generated rhythms in gene expression,

This chapter demonstrates that entrainment applies to very fast events, namely sounds with high frequencies. To illustrate this, prominent approaches to pitch perception are sketched along with basic pitch perception phenomena (e.g., virtual pitch perception). In this chapter, multiple frequency components comprise a single complex sound, and people must judge the pitch of this collection of frequencies. Both a successful psychoacoustic theory of pitch perception and a dynamic attending approach offer valid explanations of various phenomena surrounding the pitch of such sounds. This suggests t

The inner nerve ring is responsible for incorporating the sensory input from the outer ring and innervating the subumbrellar swimming muscles. Additionally, cells in the inner ring generate endogenou
