GR and MR labeling at asymmetrical synapses.

<p>Asymmetrical synapses were examined for immunoreactivity since electrophysiological evidence has examined excitatory synaptic responses of MR and GR. Compared with primary antibody omitted control asymmetrical synapses (A), immunoreactivity was observed in the postsynaptic density of GR-ir LA neurons (B) and MR-ir (MA1–620; rMR1–18 1D5) LA neurons (C and D, respectively). MR-ir was also observed at presynaptic terminals of asymmetric synapses (D). Scale bar = 100 nm.
