SLRs are stimulus specific and associative. A, SLRs supported by mossy fiber stimulation are stimulus specific. Sample traces and summary data showing that SLRs established to mossy fiber stimulation do not generalize to a white noise. Because subsequent training to the white noise enabled gabazine to unmask SLRs, this stimulus specificity of SLRs is not a result of the inability of the white noise to gain access to the AIN. B, SLRs are induced only after paired training. All traces in this figure are from CS-only trials. Infusing the GABAA antagonist picrotoxin into the AIN was ineffective before (T1) or after (T2) unpaired training, but unmasked SLRs after subsequent paired training (T3).
