Mapping of Small Nerve Trunks and Branches Using Adaptive Flexible Electrodes

Selective stimulation is delivered to the sciatic nerve using different paris of contacts on a split-ring electrode, while simulatneous recordings are acquired by the neural ribbon electrodes on three different branches. Two hook electrodes are also implanted in the muscle to monitor the activated muscle responses. It shows that the high precision implantation of electrodes, increases the effic...

A flexible method for fabrication of nerve cuff electrodes

Ahstruct A method for construction of cuff electrodes is presented. The method is based on using platinum foil electrodes fixed by rubber bands on a Teflon coated mandrel, that is then dip-coated with silicone. The method allows for design of cuff electrodes of practically any size, shape and electrode configuration, and simple cuffs can be built in less than one hour of work Cuff electrodes ha...

Nerve fibre velocity and refractory period distributions in nerve trunks.

With the use of a double stimulus technique, nerve fibre velocity range measurements were performed over a single conduction distance in 13 normal subjects and over two conduction distances in another 12 normal subjects. The velocity ranges were found to be dependent upon the conduction distance, owing to unknown refractory period delays. Refractory period values were calculated for the 12 subj...

Solitary tumours of peripheral nerve trunks.

Primary solitary tumours of the peripheral nerve trunks are relatively infrequent. Three such tumours have been treated at Hammersmith Hospital during the last four years, but a search of the hospital records for the period 1939-1950 has not shown any similar cases. (Solitary tumours of the auditory nerve and spinal nerve roots are not included in this report.) In these three patients the tumou...
