Response of single mitral cell to IPSC noise input. a, Mitral cell spike train in response to constant current input. b, Response of same cell to 400 pA current plus Poisson distributed train of α functions that we refer to as “IPSC noise” (rate, 50/s; α = 3 ms; amplitude, 60 pA). c, Power spectrum of IPSC noise input current from b (left) and average power spectrum (right) of six mitral cells given steady-state (black) and IPSC noise current injections (gray). Addition of IPSP noise resulted in a slightly broader power spectrum, mainly by enhancing the low frequency component, without affecting the frequency of the peak of the power spectrum.
