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.

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.

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)

Aligned Conducting Polymer Nanotubes for Neural Prostheses

2018 40th Annual International Conference of the IEEE Engineering in Medicine and Biology Society (EMBC), 2018
The long-term performance of neural microelectrodes relies on biocompatibility and sensitivity of the electrode-tissue interface. Current neural electrodes are limited by poor electrical performance including high initial impedance and low charge storage capacity.

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.

Classification of conductance traces with recurrent neural networks

The Journal of Chemical Physics, 2018
We present a new automated method for structural classification of the traces obtained in break junction experiments. Using recurrent neural networks trained on the traces of minimal cross-sectional area in molecular dynamics simulations, we successfully separate the traces into two classes: point contact or nanowire.

Paradoxical Preservation of Neural Conduction by Lidocaine 

Anesthesiology, 1982
The interaction of glucose lack and local anesthetic on impulse conduction was investigated in rabbit vagus nerve. Glucose lack depressed the compound action potential 50 per cent in 47 +/- 7 min (+/- SD, n = 5) and extinguished it in 69 +/- 7 min. Lidocaine hydrochloride, 0.1 mmol/1 (0.0027 g/dl), delayed the onset of inexcitability caused by glucose ...

Advances in conductive hydrogels for neural recording and stimulation

Biomaterials Science
Brain-computer interface (BCI) allows the human or animal brain to directly interact with the external environment through the neural interfaces, thus playing the role of monitoring, protecting, improving/restoring, enhancing, and replacing the human brain or body.

Excitable Membranes and Neural Conduction

2013
Neural information processing is based on three cellular mechanisms, i.e., the excitability of neural membranes, the spatio-temporal integration of activities on dendritic trees, and synaptic transmission. The basic element of neural activity is the action potential, which is a binary event, being either present or absent, much as the electrical ...
