Figure Lengend Snippet: Synaptic plasticity, circulating neurofilament light chain, and glutamate receptor subunit expression. (A) Time course of field excitatory postsynaptic potential (fEPSP) response expressed as mean peak fEPSP (% baseline) following theta burst stimulation (TBS) in hippocampal slices from saline- and morphine-treated rats. ***p < 0.001 (B) Circulating neurofilament light chain (Nf-L) concentrations measured 30 days post-surgery in saline- and morphine-treated rats. Data are presented as mean ± SEM with individual data points shown. *p < 0.05. (C-G) Protein expression of glutamate receptor subunits GluA1 (C), GluA2/3 (D), GluN1 (E), GluN2a (F), and GluN2b (G) measured in hippocampal synaptoneurosomes under baseline conditions and following a learning experience, expressed as percent of laparotomy saline baseline control. (H) Representative immunoblots for glutamate receptor subunits and GAPDH corresponding to quantified data shown in panels C-G. Data are presented as mean ± SEM with individual data points shown. *p < 0.05.
