Computing targeted responses is a general problem in goal-directed behaviors. We sought the sensory template for directional turning in the predatory sea slug Pleurobranchaea californica, which calculates precise turn angles by averaging multiple stimulus sites on its chemotactile oral veil (Yafremava LS, Anthony CW, Lane L, Campbell JK, Gillette R. J Exp Biol 210: 561-569, 2007). Spiking respo...

Transcutaneous electrical nerve stimulation (TENS) is a popular form of electrostimulation. Despite an extensive research base, there remains no consensus regarding the parameter selection required to achieve maximal hypoalgesic effects. The aim of this double blind, shamcontrolled study was to investigate the relative hypoalgesic effects of different TENS parameters (frequency, intensity and s...

BACKGROUND Cardiac resynchronization therapy (CRT) improves systolic function in heart failure patients with ventricular conduction delay by stimulating the left ventricle (LV) or both ventricles (biventricular, BV). Optimal LV site selection is of major clinical interest for CRT device implantation; however, the dependence of hemodynamics on LV stimulation site has not been established. Thus, ...

Deep brain stimulation is associated with delayed improvement of parkinsonian symptoms, such as hypokinesia with subthalamic nucleus stimulation, or dystonia with globus pallidus internus stimulation. The latency observed is better explained by molecular alterations than immediate electrophysiological processes, and clinical improvement may involve adaptive gene expression. Here, we have studie...

An unexplained phenomenon in neuroscience is the discovery that electrical stimulation in temporal neocortex can cause neurosurgical patients to spontaneously experience memory retrieval. Here we provide the first detailed examination of the neural basis of stimulation-induced memory retrieval by probing brain activity in a patient who reliably recalled memories of his high school (HS) after st...

One hundred and one patients with sustained unimorphic ventricular tachycardia underwent programmed ventricular stimulation with one of two protocols. Fifty patients underwent programmed stimulation with protocol A, which consisted of burst overdrive pacing, single, double, and triple extrastimuli at the right ventricular apex, right ventricular outflow tract, or septum, and then at the left ve...

When a saccade occurs to an interesting object, visual fixation holds its image on the fovea and suppresses saccades to other objects. Electrical stimulation of the frontal eye field (FEF) has been reported to elicit saccades, and recently also to suppress saccades. This study was performed to characterize properties of the suppression of visually guided (Vsacs) and memory-guided saccades (Msac...

in this study, the authors reported a case of woman with severe compulsion who became pregnant during the repetitive transcranial magnetic stimulation. we carried out repetitive transcranial magnetic stimulation and behavior therapy simultaneously after repeated medications' refraction. the patient received 20 sessions 1 hz repetitive transcranial magnetic stimulation in right dorsolateral...

BACKGROUND Repetitive transcranial magnetic stimulation (rTMS) is a non-invasive technique that allows cortical stimulation. Recent studies have shown that rTMS of the primary motor cortex or dorsolateral prefrontal cortex decreases pain in various pain conditions. The aim of this review was to summarize the main characteristics of rTMS-induced analgesic effects and to analyse the current data ...

The influence of central neuronal oscillators on human physiological tremor is controversial. To address this, transcranial alternating current stimulation (TACS) was delivered at peak tremor frequency to 12 healthy volunteers in a 2 × 2 crossover study. Two sites were stimulated [contralateral primary motor cortex (M1), vs ipsilateral cerebellum] while participants performed two types of tasks...
