For successful visual perception by visual prosthesis using electrical stimulation, it is essential to develop an effective stimulation strategy based on understanding of retinal ganglion cell (RGC) responses to electrical stimulation. We studied RGC responses to repetitive electrical stimulation pulses to develop a stimulation strategy using stimulation pulse frequency modulation. Retinal patc...

conclusions there was a decrease in cognitive function, including attention, visual memory, naming, and executive function, as well as psychomotor function among residents of department of anesthesiology and intensive care, faculty of medicine, universitas indonesia, who underwent 12 working hours. results cognitive stimulation” test revealed statistically significant decrease at sequential ima...

The article provides an overview of key studies on vagus nerve stimulation. stimulation method affects the fibers internal and external plexuses, enhancing parasympathetic effect. positive therapeutic effect has been achieved in various experimental clinical treatment neurological cardiac diseases, metabolic syndrome, obesity. It shown that reduces epileptic seizures frequency, arrhythmias, is ...

Neuromuscular junction endplate potentials (EPPs) decrease quickly and to a large extent during continuous stimulation. The present study examined the hypothesis that EPP rundown recovers rapidly, thereby substantially preserving neurotransmission during intermittent compared with continuous stimulation. Studies were performed in vitro on rat diaphragm, using mu-conotoxin to allow recording of ...

INTRODUCTION Neuromuscular electrical stimulation (NMES) has been shown to be an effective treatment for muscular dysfunction. Yet, a fundamental barrier to NMES treatments is the rapid onset of muscle fatigue. The purpose of this study is to examine the effect of feedback-based frequency modulation on the closed-loop performance of the quadriceps during repeated dynamic contractions. METHODS...

BACKGROUND High-frequency neuromuscular electrical stimulation increases exercise tolerance in patients with advanced chronic obstructive pulmonary disease (COPD patients). However, it is conceivable that its benefits are more prominent in patients with better-preserved peripheral muscle function and structure. OBJECTIVE To investigate the effects of high-frequency neuromuscular electrical st...

Effects of different patterns of presynaptic stimulation upon release of leuteinizing hormone releasing hormone (LHRH) were studied by monitoring LHRH-induced slow currents from individual postsynaptic neurons in bullfrog sympathetic ganglia. LHRH-mediated synaptic currents in ganglionic B and C neurons were recorded by a single-electrode voltage-clamp technique. Using continuous stimulation, r...

Multichannel techniques were used to assess the frequency specificity of activation in the central nucleus of the inferior colliculus (CIC) produced by electrical stimulation of localized regions within the ventral cochlear nucleus (VCN). Data were recorded in response to pure tones from 141 and 193 multiunit clusters in the rat VCN and the CIC, respectively. Of 141 VCN sites, 126 were individu...

We evaluated renal adrenoceptor mediation of the renin secretion and antinatriuretic responses to low frequency (1.0 Hz) electrical stimulation of the renal nerves in the dog using renal a-adrenoceptor blockade with phentolamine {a-i/a-i), prazosin (a,), yohimbine (a2), and rauwolscine (a2), and /3-adrenoceptor blockade with d,/-propranolol OS1//S2) and atenolol (/?,). In all animals studied, r...

Injury of interstitial cells of Cajal (ICC) is associated with gut dysmotility in diabetic rats. We have shown an acceleration of the colonic contractility by electroacupuncture stimulation (EAS). However, little is known about potential roles of EAS on colonic transit and ICC. In this study, we evaluate the effect of EAS on colonic transit and investigate whether apoptosis/proliferation of ICC...
