Effect of brainstem reticular formation (BRF) stimulation on spontaneous intracellular activity in barrel cortex. A: intracellular membrane potential (Vm) and field potential (FP) traces recorded during control and during BRF stimulation. Top traces: multiwhisker evoked responses (10 stimuli at 10 Hz; whisker) during control. Bottom traces: multiwhisker evoked responses starting 1 s after BRF stimulation (1 s at 100 Hz). All measurements of spontaneous activity shown in B–E were taken during the first 0.5 s after BRF stimulation. B: group data showing fast Fourier transform (FFT) power spectrum of FP activity during control and BRF stimulation (*P < 0.05 control vs. BRF stimulation). C: plot of Vm distribution for the cell in A during control and during BRF stimulation. D: peakedness (kurtosis) of the Vm distribution (means ± SE) during control and during BRF stimulation. *P < 0.01. E: Vm peak shift during BRF stimulation as a function of multiwhisker excitatory postsynaptic potential (EPSP) onset latency.
