Neuron exhibits nonlinear dynamics such as excitability transition and post-inhibitory rebound (PIR) spike related to bifurcations, which are associated with information processing, locomotor modulation, or brain disease. PIR is evoked by inhibitory stimulation instead of excitatory stimulation, presents a challenge the threshold concept. In this paper, 7 codimension-2 degenerate bifurcations 1...

promontory stimulation testing is both a valuable diagnosic tool and a crucial step in candidate selection for cochlear implantation. in this study we have compared the promontory stimulation test results between different subsets of patients with hearing loss in order to clarify the aspects of promontory stimulation which correlate best with the patients'characierisiics. patients with severe t...

postdate pregnancy is estimated to occur in 3% to 12% of all gestations. morbidity and mortality rates associated with this common obstetric problem are higher than those with term gestation. the incidence of fetal distress, birth injury, meconium aspiration, congenital malformations, macrosomia, and oligohydramnios is also greater in postdate pregnancies. we prospectively evaluated breast self...

Dopamine is a neuromodulator and neurotransmitter responsible for number of physiological processes. Dysfunctions the dopamine metabolism signalling are associated with neurological psychiatric diseases. Here we report that in primary co-culture neurons astrocytes dopamine-induces calcium signal suppress spontaneous synchronous oscillations (SSCO) neurons. Effect on SSCO was dependent could be ...

Objective: The physiological-induced conductive response has been visualised for evaluation in specific muscle compartments under hybrid ( EMS) of electrical stimulation (EMS) and voluntary resistance training (VRT) by impedance tomography (EIT). Methods: In the experiments, tendency conductivity distribution images σ over time was clearly detected three compartments, which are called AM 1 comp...

Human ?-synuclein is a 140 amino acid protein with little or no secondary structure. The ?-synuclein is expressed at high levels in the brain and enriched in neural synaptic terminals but its physiological function remains largely unknown. More recently, ?-synuclein has been shown to be one of the principal componets of Lewy bodies, neuronal inclusions that are found in diverse human neurodegen...

The current study sought to examine differences in physiological responses comfortable thermal stimuli applied the soles of feet during simultaneous presentation other sensory stimuli. As relaxing stimuli, underwater movie footage, classical music, light blue illumination, vibration trunk, and odor grapefruit oil were each presented simultaneously with a stimulus. Electroencephalography parieta...

In animals, electric field stimulation of carotid baroreceptors elicits a depressor response through sympathetic inhibition. We tested the hypothesis that the stimulation acutely reduces sympathetic vasomotor tone and blood pressure in patients with drug treatment-resistant arterial hypertension. Furthermore, we tested whether the stimulation impairs the physiological baroreflex regulation. We ...
