The goal of building this hardware was to create a
stimulation system that could operate in a real-time
feedback or control paradigm as well as the more
traditional program mode (e.g., LTP protocols). Basically,
to stimulate at any location and any time in response to
ongoing activity measured with the MEA1060 amplifier.
-Interfaces directly to the MEA1060 amplifier from
-60 channel real-time voltage stimulation
-USB (v1.2) interface using FTDI chip supported on many
-Delivers bipolar pulse (positive/negative) for balanced
-Adjustable Voltage and pulse width with 16 bit buffered
-Blanking during stimulation to attenuate artifacts
-Isolated stimulation circuit through bipolar analog solid
state switch (10 Mohm isolation).... in other words...no
noise from the stimulator itself during recordings
-TTL sync output through BNC to mark stimulation delivery
(e.g., connected to A1 on multichannel systems MEA1060)
-Programmable stimulation pulse trains.
-The USB interface has drivers for windows, mac, and linux
standard serial connections...
stim ch# or stim ch#,ch#,...
-Voltage stimulation only...obviously if you change or add
an additional DAC you could do current as well..
-Limited program stack...up to 50 commands at any time
-There is a 20 uS lag between serial stimulation pulses
while the microcontroller sets up the switches
