One variation of a system for locating electrodes on a head of a user includes a headset defining a set of electrode bodies elastically interconnected by a unique set of spring elements configured to locate the set of electrode bodies at electrode positions of the international 10-20 standard, irrespective of the size of the head of the user. The spring elements are configured to carry electrical signals between interconnected electrode bodies and ultimately to a controller. An electrode tip is mechanically and electrically coupled to each electrode body. The electrode tip comprises a thin conductive probe mounted at the distal end of an elastic beam and is configured to extend from a base of the electrode tip, bypass hair, and electrically couple to the head of the user, and an insulative boss, configured to rest on and transfer the weight of the headset to the head of the user.

A system for reducing and/or eliminating noise in chronic neural recording of low amplitude neural signals from conscious, freely-moving subjects. Triboelectric noise effects are reduced or eliminated using in implant lead with insulating materials with charge affinities separated by 10 nC/J or less. The recording device can include a preamplifier device that uses capacitors with a low-distortion dielectric material.
