A low-cost, 3 channel neural stimulator.
An inexpensive design using minimal components is generally described. A choice is provided for the behaving animal between 2 primary channels that are disabled once the choice is made. A third channel acts as the reset and must be activated after each choice is made of the primary channels. Each channel is capable of providing independent control over pulse train duration, frequency and voltage. The reset channel may be electrically silent if desired. An innovative use is made of high output impedance solid state analog switches to isolate the outputs of the 3 channels as they are connected together to the single ICS electrode.
