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.

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

The neurons exhibit variations in gain and spike timing precision related to the frequency of stimulation. These phenomena are influenced by spike-frequency adaptation and nonlinearities in the PSP.

To isolate the effects of gamma-motoneurons the leg was fixed in place for recording and denervated except for soleus muscle. Because gamma-motoneurons produce marked effects on the stretch sensitivity of muscle afferents, soleus muscle was oscillated about a present length so the stretch sensitivity of its afferents could be

In natural environments complex and continuous auditory stimulation is virtually ubiquitous. The human auditory system has evolved to efficiently process an infinitude of everyday sounds, which range from short, simple bursts of noise to signals with a much higher order of information such as speech. Investigation of temporal processing in this system using the event-related potential (ERP) technique has led to great advances in our knowledge. However, this method is restricted by the need to present simple, discrete, repeated stimuli to obtain a useful response. Alternatively the continuous a

1. Recordings were made from direction-selective neurons in the nucleus of the optic tract (NOT) and dorsal terminal nucleus (DTN) of the wallaby, Macropus eugenii. Responses were elicited in the cells by brief displacements of a wide-field sine wave grating pattern in their preferred and antipreferred directions. The grating pattern was moved by a quarter cycle or less during the experiments. Once the stimulus duration was less than a certain value, referred to as the integration time, the magnitude of the responses depended on the size of the displacement, regardless of the velocity of the m

Activity-dependent fluctuations in axonal excitability and changes in interspike intervals modify the conduction of trains of action potentials in unmyelinated peripheral nerve fibers. During inflammation of a nerve trunk, long stretches of axons are exposed to inflammatory mediators such as 5-hydroxytryptamine [5-HT]. In the present study, we have tested the effects of m-chlorophenylbiguanide (mCPBG), an agonist at the 5-HT(3) serotonin receptor, on activity- and potential-dependent variations in membrane threshold and conduction velocity of unmyelinated C-fiber axons of isolated rat sural ne

Summary. Complex Regional Pain Syndrome Type I (CRPS I) (G90.5) is a set of condi- tions accompanied by regional pain that is disproportionate in time and degree relative to the normal course of the post-traumatic period or other lesion, does not correspond to the zones of innervation of certain nerves or nerve roots and is usually manifested by sensory, motor, vasomotor, and/or trophic disorders in distal extremities. A multidisciplinary consensus on the basic principles of diagnosis and treatment of complex regional pain syndrome type 1 was adopted at a round table meeting at the XVIII Congr

The pulse width of rectangular stimuli was 0.3 ms and repetition frequency was 25 Hz. The frequency of sinusoidal stimuli was 2 500 Hz, chopped by a 25 Hz rectangular signal. Thirteen healthy subjects were involved in the study and divided into three groups. The first group (A) had stimulation with rectangular impulses, the second (B) with sinusoidal impulses and the third (C) was a control group.

This reduction of EPC amplitudes is predominantly of presynaptic origin, although an observed decrease in MEPC amplitudes suggests that some postsynaptic changes [due to direct action of HC-3 on acetylcholine (ACh) receptors or on open ACh channels] also occurs. 2.

Inhalation of cigarette smoke into the lower airway via a tracheostomy evokes immediate apnea, bradycardia, and systemic hypotension in dogs. These responses can still be evoked when conduction in myelinated vagal fibers is blocked preferentially by cooling but are abolished by vagotomy, suggesting that they are mediated by afferent vagal C-fibers. To examine this possibility, we recorded impulses in pulmonary C-fibers in anesthetized, open-chest dogs and delivered 120 ml cigarette smoke to the lungs in a single ventilatory cycle.
