Cortical control of the sensory output of muscle spindles was studied in thirteen anesthetized cats in the present experiment. Gamma motoneuron activity was monitored during electrical stimulation of the sensorimotor cortex while recording from single primary afferents from the tenuissimus muscle. Findings are as follows: 1. The state of anesthesia is crucial in obtaining reproducible resu...

over the past three decades physicians have used light level laser therapy (lllt) for the management and the treatment of diabetic peripheral neuropathy and have obtained results that calls for further investigations. this study aimed to investigate the effectiveness of lllt in treatment of pain symptoms in patients with diabetic polyneuropathy. in this study 60 patients with diabetic periphera...

We studied the effects of intense sympathetic stimulation on the chronotropic responses of the heart to subsequent test stimulations of the cardiac autonomic nerves in dogs anesthetized with a-chloralose. Such intense sympathetic stimulations (which we refer to as "release stimulations") are known to release neuropeptide Y as well as norepinephrine. The changes in cardiac cycle length evoked by...

To assess whether intraoperative subcortical mapping of the visual pathways during brain surgeries was feasible. Subcortico-cortical evoked potentials (SCEPs: 30 stimulations/site, biphasic single pulse, 1.3 Hz, 0.2 ms/phase, maximum 10 mA; bipolar probe) were measured in 12 patients for stimulation optic radiation, Meyer’s loop or nerve. Recorded sites bilateral central, parietal, parieto-occi...

Electrical recruitment of the upper airway (UAW) muscles has been attempted as a treatment method for Obstructive Sleep Apnea (OSA) [l-61. Hypoglossal nerve (HG) and genioglossus muscle (GG) stimulations have given successful results in OSA patients [3-61. A reliable method for detection of obstructions is needed to trigger the stimulations in phase with respiration during obstructive breaths b...

We investigated whether and how temporary shifts in self-construals modulate neural correlates of pain perception. Event-related potentials (ERPs) to painful and non-painful electrical stimulations were recorded from adults after being primed with independent and interdependent self-construals. Electrical stimulations to the left hand elicited two negative components (N60 and N130) over the fro...

We experimentally show that the neuron functions as a precise time integrator, where the accumulated changes in neuronal response latencies, under complex and random stimulation patterns, are solely a function of a global quantity, the average time lag between stimulations. In contrast, momentary leaps in the neuronal response latency follow trends of consecutive stimulations, indicating ultraf...

OBJECTIVE To provide information about activation of descending motor pathways in humans, motor evoked potentials were obtained from 16 patients without any sensorimotor deficit, after both cortical and brain stem stimulation. METHOD Total anesthesia was achieved in all patients through intravenous administration. Short trains of one to five electrical pulses were delivered separately to the ...
