CED Whisker Stimulator 3901

Controls an array of piezo-electric stimulator elements

The CED 3901 whisker stimulator is a controller for an array of piezo-electric stimulator elements, offering precisely controlled temporal patterns, with repeatable stimulation. Each 3901 drives 9 stimulator elements and up to 7 can be linked, to control up to 63 elements.

It is mains-powered and is controlled by 8 bits of the digital output of a CED 1401, or by USB. Each of the stimulator elements can be connected to one of four sources; either of the two external waveform inputs, an individual programmable pseudo-random noise generator, or mute.

Software control is provided as a demonstration Spike2 script.
