Morphological and electrophysiological properties of neural cells are substantially influenced by their immediate extracellular surroundings, yet the features of this environment are difficult to mimic in vitro. Therefore, there is a tremendous need to develop a new generation of culture systems that more closely model the complexity of nervous tissue. To this end, we engineered novel electroph...

Thirty-two patients with motor neurone disease were investigated using quantitative electrophysiological techniques. Estimates of the number of surviving motor units in the extensor digitorum brevis muscle and measurements of the electrophysiological parameters of these units are present along with the values for motor nerve conduction velocities. The results indicate that reinnervation in moto...

spasticity is one of the common complications in upper motor neuron lesions and without appropriate treatment it causes disturbances in movement pattern. assessments of patients are effective in patient`s management. modified ashworth scale (mas) is one of the criteria in qualitative assessment of spasticity, and there are lots of controversies about its validity. the purpose of this study is t...

The behavior of neural circuits is determined largely by the electrophysiological properties of the neurons they contain. Understanding the relationships of these properties requires the ability to first identify and catalog each property. However, information about such properties is largely locked away in decades of closed-access journal articles with heterogeneous conventions for reporting r...

In order to determine the mechanism of action of edrophonium on the cardiac conduction system, we used His bundle recording and pacing techniques to examine the electrophysiological effect of edrophonium in 6 patients undergoing diagnostic evaluation for coronary artery disease and in 9 cardiac transplant recipients who were free of acute graft rejection. After control measures were made of sin...

Impulsivity has proven to be an important psychological construct reflected in both normal and pathological human behaviors and traits. However, the definition, measurement, and manifestations of the construct are varied and multifarious. Impulsive behaviors are observed in a wide range of psychiatric/behavioral disorders, including alcohol/substance use and abuse disorders (AUDs/SUDs), conduct...

Organic bioelectronics involves the connection of organic semiconductors with living organisms, organs, tissues, cells, membranes, proteins, and even small molecules. In recent years, this field has received great interest due to development all kinds devices architectures, enabling detection several relevant biomarkers, stimulation sensing cells recording electrophysiological signals, among ot...

BACKGROUND The main purpose of this study is to determine the correlation of inter- and intraatrial conduction times between the electrophysiological and tissue Doppler echocardiographic measurements, and to evaluate the appropriateness of tissue Doppler echocardiography for this measurement. METHODS One-hundred and one patients were included in the study who underwent electrophysiological st...

Diaphragmatic dysfunction is a common postoperative complication of cardiac surgery in children, with important effects on respiratory morbidity. Its early diagnosis, followed by prompt surgical intervention, has been shown to reduce morbidity. However, the commonest method of diagnosis, based on hemi-diaphragmatic elevation on the chest radiograph, may be less accurate than direct techniques f...
