Selective block of AOB sustained responses was mediated via GABAA receptors. A, C, Extracellularly recorded current traces of the responses of MOB mitral cells to SF stimulation before (A) and during (C) application of 2.5 μm gabazine to the recording chamber. B, D, Same for AOB mitral cell before (B) and during (D) application of 2.5 μm gabazine. E, PSTHs (each averaging 5 responses to identical stimuli) of the responses of the MOB mitral cell shown in A and C before (black) and during (gray) gabazine application. The MOB response remained transient after blockade of GABAA receptors. Stimulus strength was 1000% of just-suprathreshold level. Bin duration, −0.5 s. F, PSTHs of the responses of the AOB mitral cell shown in B and D before (black) and during (gray) gabazine application. This AOB neuron belonged to the 28% of AOB neurons displaying prolonged inhibition after the initial transient firing response. The excitatory response was sustained after blockade of GABAA receptors. Stimulus strength was 250% of just-suprathreshold level. Note the different scales of y-axes between E and F.
