Location of microdialysis probes and recording electrodes in the amygdala. (A) Positions of the tips of microdialysis probes for application of an NPSR antagonist or ACSF into the ITC area of the amygdala, lateral to the CeA, in behavioral studies; n = 14. (B) Positions of the tips of microdialysis probes for application of NPSR antagonists into the ITC area in electrophysiology experiments; n = 5 normal, n = 18 arthritis. (C) Position of the tips of the glass insulated carbon filament electrodes for extracellular recordings of individual amygdala neurons in the central nucleus (CeA); n = 5 normal, n = 20, arthritis. Open circles, data from normal rats; filled circles, data from arthritic rats.
