Abstract

A telestimulator has been constructed which is suitable for mounting on the heads of medium-sized Macaca mulatta or larger primates. It differs from previous units in that the battery supply is continuously recharged from ambient light by means of solar cells. The system features remote control of all stimulus parameters, constant current output, and remote selection of any of 11 electrodes. If additional transmitters are employed, simultaneous and independent stimulation of a number of primates in the same group is possible. A shielded room with a terminated antenna system is used to produce a homogeneous radio-frequency field for laboratory use.
