background headache is one of the most prevalent investigated complaints in the neurology clinics and is the most common pain-related complaint worldwide. stress is a significant factor that causes and triggers headaches. since healthcare practitioners experience a lot of stress in their careers, they are more prone to headaches. objectives this study was designed to evaluate and compares the e...

introduction: it is believed that locus coeruleus (lc) influences the sensory information processing. however, its role in cortical surround inhibitory mechanism is not understood. in this experiment, using controlled mechanical displacement of whiskers we investigated the effect of phasic electrical stimulation of lc on response of layer v barrel cortical neurons in anesthetized rat. methods: ...

Neurorehabilitation effective delivery for stroke is likely to be improved by establishing a mechanistic understanding of how to enhance adaptive plasticity. Functional electrical stimulation is effective at reducing poststroke foot drop; in some patients, the effect persists after therapy has finished with an unknown mechanism. We used fMRI to examine neural correlates of functional electrical...

Understanding cortical organization is key to understanding brain function. Distinct neural networks underlie the functional organization of the cerebral cortex; however, little is known about how different nodes in the cortical network interact during perceptual processing and motor behavior. To study cortical network function we examined whether the optical imaging of intrinsic signals (OIS) ...

the objective of this study was to describe the role of electrical stimulation in controlling peripheral vertigo. in a prospective study on 13 healthy volunteers, nystagmus was induced with caloric stimulation and the interval of nystagmus disappearance was recorded. this time indicates the basal response of vestibular end-organ. after caloric irrigation, pulsed signal was applied for each pers...

PURPOSE To establish whether it is possible to improve orbicularis oculi muscle function in the eyelids of patients with a chronic seventh cranial nerve palsy by using transcutaneous electrical stimulation to the point at which electrical stimulation induces a functional blink. METHODS Ten subjects (one woman, nine men) aged 36 to 76 with chronic, moderate to severe facial nerve palsy were re...

Total brain acetylcholine (ACh) was assayed in groups of animals after various periods of operant responding maintained by electrical stimulation of the lateral posterior hypothalamus or of escape behavior induced by electrical stimulation of the midbrain tegmentum. Different groups of trained rats were placed in identical Skinner boxes for periods of 1 to 24 hr. The following groups were studi...

Objectives: One of the most common and disabling complications that affects individuals with spinal cord injury is spasticity. The purpose of this study is to compare the effect of agonist and antagonist electrical stimulations on triceps surae muscle spasticity in patients with spinal cord injury. Methods: A total of 30 subjects with spinal cord injury were considered for the study. They were...
