Low-frequency stimulation of the parabrachial input to CeL neurons induces LTD A, average normalized EPSC amplitude in which the parabrachial input (•) and a control input from the BLA (^, lower panel) were alternatively stimulated at 0.1 Hz. At time 0, the parabrachial input was stimulated at 1 Hz for 900 stimuli which led to a large reduction in EPSC amplitude. Average EPSC from the time points indicated in A are shown in B for the parabrachial input (upper traces) and the BLA (lower traces). C, normalized paired-pulse ratio for the inputs shown in A. No changes were observed in the paired-pulse ratio.
