Hair Bundles of a Jawless Vertebrate Employ Tetrapod-Like Tuned Mechanical Amplification
… regime in which their active process drives spontaneous oscillations. Studying this epiphenomenon can reveal mechanisms underlying the amplifying abilities of hair bundles. Despite the importance of amplification in hearing, little is known regarding the evolution of the active process; it is …

A Model of the Production of Spontaneous Otoacoustic Emissions in the Tokay Gecko
… into the environment. These sounds, known as spontaneous otoacoustic emissions, are the most striking proof of the existence of an active process within the ear. This active process originates in hair cells, the sensory receptors of the inner ear; by augmenting the energy contained in sound, …

Thermally-actuated piezoresistively-sensed mechanical silicon oscillator
… loop excite the mechanical structure, causing spontaneous oscillations. We begin with the investigation of scaling trends based on an equivalent circuit model of the device. Targeting high frequency oscillators, we design suitable geometries and discuss the microfabrication processes used to …

Tuning of the Active Hair Bundle
… channels and myosin molecules that power both spontaneous and evoked movements. Active hair-bundle motility serves two functions: it mechanically amplifies sensory stimuli; and it regulates their transduction into electrical signals that drive the hair-cell synapse. To characterize these two …

Pacemaking Neurons in the study of Parkinson’s Disease
… level of arborisation and pacemaking activity. Spontaneous oscillations of these neurons are an important feature of motor control. Pacemaking involves the L-type calcium channel, and could impose long-term accumulation of calcium within its organelles. Modelling of this activity is an important …

Nonlinear dynamics of blood flow in simple microvascular networks
<p>It has been found that spontaneous oscillations of nodal pressures, hematocrit, and blood velocity can occur in microvascular networks in the absence of biological control. In this paper, both analytical and numerical methods have been used to investigate the nonlinear dynamics of microvascular …

The influence of acute, chronic and lifelong hypoxia on the functional and structural integrity of the neurovascular unit
… assessed using transfer function analysis during spontaneous oscillations in MAP and MCA<sub>V</sub>/ PCA<sub>V</sub>; and 2, neurovascular coupling (NVC) via PCA<sub>V</sub> responses to repeated dark (eyes closed) and light (eyes open + visual stimulation) activation. …

Dynamics of Cilia and Flagella
Cilia and flagella are hair-like appendages of eukaryotic cells. They are actively bending structures that exhibit regular beat patterns and thereby play an important role in many different circumstances where motion on a cellular level is required. Most dramatic is the effect of nodal cilia whose …
