(a) Ramped experiment to determine intracellular threshold Ie with dissociated rat neurons. (b) Integrated Ve,noise for an individual pixel without an interfacing neuron (left) and Ve amplitude integrated from 100 Hz - 4.7 kHz across the array below threshold for the experiment of (a). (c) Excitatory PSP (EPSP) measurement. (d) Stimulation is achieved through adjustment of Ie.
