One form of electrophysiological therapy, low frequency impulse electrotherapy, makes use of electrical impulses of very low voltage and frequency. The low frequency impulsed current affects the skin's outer layer, causing an electrolytic effect and a powerful stimulation of nerves, which in turn activates the nerves, improves local blood circulation, and, most importantly, provides analgesia. The frequency, time, waveform, and duty cycle of the electrical pulse have a significant impact on the efficacy of low frequency impulse therapy. The design is built on an Arduino UNO development board,

Introduction: The vestibular implant could become a clinically useful device in the near future. This study investigated the feasibility of restoring the high-frequency dynamic visual acuity (DVA) with a vestibular implant, using the functional Head Impulse Test (fHIT). Methods: A 72-year-old female, with bilateral vestibulopathy and fitted with a modified cochlear implant incorporating three vestibular electrodes (MED-EL, Innsbruck, Austria), was available for this study. Electrical stimulation was delivered with the electrode close to the lateral ampullary nerve in the left ear. The high-fre

A conditioning impulse in human muscle fibers induces a prolonged phase of increased velocity (also called supernormality) with two phases related to an early and late afterpotential. We investigated the effects of intermittent 37-Hz stimulation on muscle fiber supernormality and found that the early and late phases of supernormality changed differently, and that the late phase may reflect the ionic interactions responsible for the counter-regulation of muscle fatigue.

Optical cochlear implant is an emerging applied technology of stimulating auditory neurons by using pulsed laser light as a stimulus to evoke neural activity instead of electrical currents. Laser stimulation has more potential in accuracy and high frequency resolution than electrical stimulation. In this paper we demonstrated a fiber laser system (980nm) to irradiate on guinea pig cochlear in vivo for the first time. The pulsed laser stimulation successfully evoked auditory nervous impulse, similar to acoustic stimulation. And the performance under different laser pulse intensity and pulse wid

In a crayfish phasic neuromuscular junction, we have demonstrated low-frequency depression (LFD), high-frequency depression (HFD), and long-term facilitation (LTF) in response to different regimens of stimulation. Chronic stimulation of the phasic axon supplying the closer muscle of the claw in Procambarus clarkii resulted in diminished expression of HFD and LTF. Conversely, when impulse production in the phasic motoneuron was reduced by claw immobilization, both HFD and LTF were enhanced. LFD was insensitive to these manipulations. These results provide further evidence for long-term adaptati

Impulse encoding across the dendritic morphologies of retinal ganglion cells. Nerve impulse entrainment and other excitation and passive phenomena are analyzed for a morphologically diverse and exhaustive data set ( n = 57) of realistic (3-dimensional computer traced) soma-dendritic tree structures of ganglion cells in the tiger salamander ( Ambystoma tigrinum) retina. The neurons, including axon and an anatomically specialized thin axonal segment that is observed in every ganglion cell, were supplied with five voltage- or ligand-gated ion channels (plus leakage), which were distributed in acc

To clarify the role of presynaptic L-type Ca2+ channels in GABA-mediated transmission in the medial preoptic nucleus (MPN), spontaneous, miniature, and impulse-evoked inhibitory postsynaptic currents (sIPSCs, mIPSCs, and eIPSCs, respectively) were recorded from MPN neurons in a slice preparation from rat brain. The effects of different stimulus protocols and pharmacological tools to detect contributions of L-type Ca2+ channels and of Ca2+-activated K+ (KCa) channels were analyzed. Block of L-type channels did not affect the sIPSC and mIPSC properties (frequency, amplitude, decay time course) i

The goal of the study was to compare the tolerability and the effects of conventional subthalamic nucleus (STN) and combined subthalamic nucleus and substantia nigra (STN+SNr) high-frequency stimulation in regard to neuropsychiatric symptoms in Parkinson’s disease patients. In this single center, randomized, double-blind, cross-over clinical trial, twelve patients with advanced Parkinson’s disease (1 female; age:61.3±7.3years; disease duration:12.3±5.4years; Hoehn and Yahr stage:2.2±0.39) were included.

ABSTRACT Background: The video head impulse test (vHIT) is a recent technique for functional evaluation of semicircular canals (SSCs). The vHIT examines eye movements at high frequencies of stimulation and provides an objective assessment of the functioning of the high-frequency domain of the vestibular system. Objective: To describe the results from vHIT performed using two systems. Methods: All subjects were evaluated through an audiological and otoneurological battery of tests and were diagnosed as normal or abnormal by an otorhinolaryngologist. The results from two systems: 1. ICS Impulse

Neurodegenerative diseases are going to increase as the life expectancy is getting longer. Most patients with neurodegenerative diseases (ND) complain of pain, the origin of which remains largely unknown and requires further research. One of the reasons why the topic of pain and PD is difficult to address is that it is sometimes tough to discern whether a particular pain is due to PD or not. Chronic pain is such a common symptom among the general population, and people with PD are not immune to common problems as well. However, there are aspects of PD that may exacerbate the pain experienced f

Although the so-called low-frequency (around 0.1Hz) components of heart rate variability are an accepted marker of sympathetic activity to the heart and the circulation, their origin remains elusive. In order to characterise the frequency response of the heart and the vessels to the stimulation of the arterial baroreceptors we applied the neck suction technique with a sinusoidal function at different frequencies, and studied the changes in the cardiovascular system. In all subjects the neck suction induced RR interval oscillations at both low- (0.10Hz) and high (0.20Hz) frequencies, but with g
