Figure Lengend Snippet: Effect of PFC D5R knockdown on oscillatory power activity in rats. Effect of PFC D5R knockdown on oscillatory power activity in rats. (A–D) Power spectra (left and center panels) and quantification of power (right panels) are shown. PFC D5R knockdown had the following regional effects on spectral power, (A) increased theta power in PFC, (B) increased theta power in OFC, and (C) increased theta power in HIP. (D) No effects of PFC D5R knockdown were evident in spectral power in the thalamus. Power curves are presented as normalized data with jackknife estimates of SEM shown as shaded areas. Quantified data are expressed as percent control. N = 7–8 rats/group, 1–2 electrodes/region/rat. * p < 0.05 Student's t test.

Figure Lengend Snippet: Effect of PFC D5R knockdown on oscillatory coherence in rats. (A–F) Coherence spectra (left panels) and quantification (right panels) are shown. (A) PFC D5R knockdown increased PFC‐OFC theta coherence, and (B) reduced PFC–thalamus high gamma coherence. (C–F) No significant effects on coherence were observed between PFC–HIP, OFC‐HIP, OFC‐thalamus, or thalamus‐HIP. Coherence curves are presented with jackknife estimates of SEM shown as shaded areas. Quantified data are expressed as percent control. N = 7–8 rats/group, 1–2 electrodes/region/rat. * p < 0.05, ** p < 0.01 Student's t test.

Figure Lengend Snippet: D5R knockdown in PFC induces deficits in learning and memory. (A) D5R knockdown in PFC induced deficits in object recognition memory in the NOR test. (B) Impaired spatial memory in the OL test was also evident. (C) D5R knockdown also induced impairment in associative recognition memory when tested in the OiP. (D) In the Y‐maze, D5R knockdown had no effects on short‐term recognition memory (left panel) but resulted in impairment on long‐term memory (right panel).
