LC activation increases perithreshold mitral cell responses to olfactory epithelium (OE) stimulation. PSTHs showing responses of a mitral cell to perithreshold OE stimulation (atsolid bar indicated by arrow) before and during activation of LC by two intracoerulear microinjections of ACh (arrows at right). Three PSTHs were recorded before and during LC activation. LC activation substantially increased the epithelium-evoked excitation of this mitral cell. The mean excitatory response magnitude increased from 90 ± 5.8 to 202.3 ± 9.8 spikes/100 sweeps. This is an increase of 124%. All PSTHs were generated for 100 consecutive epithelium shocks delivered at 1 Hz.
