Conduction of neural impulses in diabetic neuropathy

Clinical Neurophysiology, 2003
To measure the conduction velocity, absolute refractory period and duration of the action potential for individual afferents of the median nerve in diabetic patients and to examine correlations between measures and with temperature and compare this to data from normal subjects.The technique of percutaneous microneurography was used to record from ...

Altered Neural Conduction with Epidural Bupivacaine

Anesthesiology, 1982
The sites and magnitude of evoked potential response alterations induced by varying masses and concentrations of epidurally administered bupivacaine were assessed from electrodes positioned along the conducting pathways of the monkey. The mass of bupivacaine was the major factor in determining the level and degree of response alterations.

Osmotic Swelling Effects on Neural Conduction

Anesthesiology, 1979
Local anesthetics administered intrathecally seen more effective when in hypobaric solution than when in hyperbaric solution. To test whether an unrecognized osmotic effect might be playing a part in this, sheathed vagus nerves of rabbit were incubated in electrolyte-deficient or electrolyte-free media of various degrees of hypo-osmolarity.

Conductivity estimation by neural network

IEEE Antennas and Propagation Society International Symposium. 1995 Digest, 2002
Presents a technique for detecting conductivity anomalies in sediments, e.g., a buried object in sedimentary layers under sea water, by using the neural network approach. The electric field values are used as the inputs to the neural network and the associated conductivities are treated as the targets.

Development of bioactive conducting polymers for neural interfaces

Expert Review of Medical Devices, 2010
Bioelectrodes for neural recording and neurostimulation are an integral component of a number of neuroprosthetic devices, including the commercially available cochlear implant, and developmental devices, such as the bionic eye and brain-machine interfaces.

An injectable high-conductive bimaterial scaffold for neural stimulation

Colloids and Surfaces B: Biointerfaces, 2020
Neurological recovery is difficult due to limited axonal regeneration and the limitations of autograft therapeutics in repairing peripheral nerve defects. Alternatively, the implantable nerve guidance conduit represents a promising approach for the nerve regeneration of especially large injury gaps.

Imaging of neural conduction block by neuromagnetic recording

Clinical Neurophysiology, 2002
For the clinical application of neuromagnetic recordings in neural conduction block, the patterns of magnetic fields in the region should be clarified. Using an experimental in vitro model, the spatiotemporal course of the neuromagnetic fields at the site of complete conduction block was examined. Additionally, the magnetic compound action fields (CAFs)
