Abstract:
:Epoxy-insulated tungsten microelectrodes can be used once or twice in our lab before the impedance becomes too low. Dipping the electrodes in epoxy followed by curing restores their initial high impedance which is associated with good isolation of single neurons. It is a cost effective and simple procedure.

杂志文章abstract::A method for quantifying nociceptive withdrawal reflex receptive fields in human volunteers and patients is described. The reflex receptive field (RRF) for a specific muscle denotes the cutaneous area from which a muscle contraction can be evoked by a nociceptive stimulus.
