    Tocris dreadd agonist compound 21
    Effects of SST+ interneuron activation across different stages of spatial memory processing (A) Male and female SST-CRE mice ( n = 9 animals/group for encoding and consolidation; n = 14–15 animals/group for retrieval) are transduced to express Cre-dependent hM3Dq-mCitrine or EGFP (control) in DG. Beginning four weeks after viral transduction, SST+ interneurons were activated separately either during OLM encoding, consolidation, or retrieval, with two weeks of rest between OLM trials, which ended with a final trial in which vehicle is administered prior to encoding. (B) Timing of <t>compound</t> <t>21</t> (C21) administration relative to OLM encoding, consolidation, or retrieval. Mouse interaction with the moved vs. unmoved object is quantified to generate the OLM discrimination index (DI). (C–E) Discrimination index scores for encoding (C), consolidation (D), and retrieval (E) sessions in mice expressing EGFP or hM3Dq in SST+ interneurons. two-way ANOVA (Phase × AAV) revealed a significant main effect of AAV (F(1,58) = 7.40, p = 0.0086), indicating that the chemogenetic activation of SST+ interneurons influences DI performance independent of behavioral phase. Neither the main effect of Phase (F(2,58) = 1.69, p = 0.1936) nor the Phase × AAV interaction reached significance (F(2,58) = 2.41, p = 0.0985), though the interaction showed a trend. Closer inspection of the data showed the largest effects of SST+ interneuron activation on OLM encoding ( p = 0.0047, Tukey’s test) and retrieval ( p = 0.046, Tukey’s test), but had no effect on consolidation ( p = 0.8804). (F) Vehicle administration did not affect OLM encoding ( p = 0.755, n = 8–9 animals/group). For all panels, # p < 0.1, ∗ p < 0.05. Data are presented as mean ± SEM.

    Effects of SST+ interneuron activation across different stages of spatial memory processing (A) Male and female SST-CRE mice ( n = 9 animals/group for encoding and consolidation; n = 14–15 animals/group for retrieval) are transduced to express Cre-dependent hM3Dq-mCitrine or EGFP (control) in DG. Beginning four weeks after viral transduction, SST+ interneurons were activated separately either during OLM encoding, consolidation, or retrieval, with two weeks of rest between OLM trials, which ended with a final trial in which vehicle is administered prior to encoding.
