Paradoxical Preservation of Neural Conduction by Lidocaine
Anesthesiology, 1982The 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 ...

Aligned Conducting Polymer Nanotubes for Neural Prostheses
2018 40th Annual International Conference of the IEEE Engineering in Medicine and Biology Society (EMBC), 2018The 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.

Classification of conductance traces with recurrent neural networks
The Journal of Chemical Physics, 2018We 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.

Tunable Conductive Hydrogel Scaffolds for Neural Cell Differentiation
Advanced Healthcare Materials, 2022AbstractMultielectrode arrays would benefit from intimate engagement with neural cells, but typical arrays do not present a physical environment that mimics that of neural tissues. It is hypothesized that a porous, conductive hydrogel scaffold with appropriate mechanical and conductive properties could support neural cells in 3D, while tunable ...

Advances in conductive hydrogels for neural recording and stimulation
Biomaterials ScienceBrain-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.

Predicting Conductance Due to Upconing Using Neural Networks
Groundwater, 2005Abstract Artificial neural networks (ANNs) were developed to accurately predict highly time‐variable specific conductance values in an unconfined coastal aquifer. Conductance values in the fresh water lens aquifer change in response to vertical displacements of the brackish zone and fresh water–salt water interface, which are caused ...

Neural conduction time and steady-state evoked potentials
Electroencephalography and Clinical Neurophysiology/Evoked Potentials Section, 1985Signal processing in neural networks will inevitably include delays due to the finite conduction velocity of the neurones and their interconnections. Diamond proposed a method for finding these delays in the case of (visual) steady-state responses. Alignment of response features, when represented in a time domain plot, would, allegedly, yield the delay.

Learning population of spiking neural networks with perturbation of conductances
The 2013 International Joint Conference on Neural Networks (IJCNN), 2013In this paper a method is presented for learning of spiking neural networks. It is based on perturbation of synaptic conductances. While this approach is known to be model-free, it is also known to be slow, because it applies improvement direction estimates with large variance.

Excitable Membranes and Neural Conduction
2013Neural 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 ...

Conducting Polymers in Neural Stimulation Applications
2009With advances in neural prostheses, the demand for high-resolution and site-specific stimulation is driving microelectrode research to develop electrodes that are much smaller in area and longer in lifetime. For such arrays, the choice of electrode material has become increasingly important.
