L-LTP and fear LTM did not differ between WT, CamKII- Cre and floxed mice. a) Similar L-LTP was induced by four tetanic trains in slices from WT ( +/+;+/+, n = 7) αcamkii-cre ( +/+;Cre/+, n = 6) and floxed mice ( flox/flox;+/+, n = 6) (at 22 min (2,17) =.54, p =.95). b) or contextual fear conditioning, freezing times were determined before the conditioning (Naïve, during 2-min period) and then 24 h after training (during a 3-min period). Similar freezing at 24 h reflects normal contextual LTM in WT (n = 7), αcamkii-cre (n = 7) and floxed (n = 7) mice ( (2,19) =.241, p =.79). c) or auditory fear conditioning, freezing times were measured 24 h post-training either before the onset of the tone (Pre-CS, 2 min) or during the tone presentation (Post-CS, 3 min) (n = 7 per group, (2,19) =.662, p =.94).

Lack of Rictor does not alter gross brain morphology or synaptic markers. a) Nissl-stained hippocampal sections from WT and fb-ko mice. b) Antibodies against synaptophysin (t =.152; p =.885), PSD95 (t =.147; p =.889) and AD67 (t =.289; p =.784) showed no difference in CA1 between WT (n = 3) and fb-ko mice (n = 4).

The results, including effects of selective antagonists APV, MK81 and NBQX (for glutamate), and TrkB-c (for BDN), are summarized in d-f. All comparisons are made with control (untreated) group. APV (aminophosphonovalerate) and MK81 block NMDA receptors; BNQX (dihydroxy-nitro-sulfamoyl-benzoquinoxaline-dione) blocks AMPA-type glutamate receptors. ns = no significance.

Basal synaptic transmission in CA1 does not differ between slices from control and fb-ko mice. a) Plots of presynaptic fiber volley as function of stimulus intensity show no difference in fiber excitability between control (n = 26) and fb-ko mice (n = 21). The data were fitted by linear regressions: R 2 =.991 for controls and.9838 for fb-ko mice. b) Input-output plots show similar EPSPs as function of presynaptic fiber volley amplitude over a wide range of stimulus intensities. The corresponding linear regressions are: R 2 =.6983 for controls and.7392 for fb-ko mice. c) Paired-pulse facilitation of fepsps also did not differ between WT and fb-ko mice, as shown by the plots of the PP ratio (fepsp 2 / fepsp 1 ) for various intervals of paired stimulation.

Control tests of actin polymerization promoter jasplakinolide (JPK) and inhibitor cytochalasin-d (Cyt-D). a) In slices from fb- KO mice, JPK ( nm) had no effect on basal synaptic transmission expressed by fepsps (n = 5 per group, t = 1.81; p =.12). b) In WT slices Cyt-D ( nm) did not affect early-ltp induced by a single high frequency train ( Hz, 1 s). or these plots, n = 5 for controls (vehicle) and 6 for Cyt-D: at 2 min ( (1, 1) =.42, p =.993). Inset: averaged traces were obtained before and after prolonged application of JPK (a) or before and after 2 min after tetanus (b).

A low dose of JPK infused into the hippocampus promotes actin polymerization in fb-ko mice. a) Western blots show that thirty min after infusion of JPK ( ng/ml) in the dorsal hippocampus from fb-ko mice the -actin/-actin ratio was increased (at left; n = 4, t = 2.942; * p <.5), but not in the dorsal hippocampus from WT mice (at right; n = 3, t = 1.57; p =.187). Normalized data are shown below. b) Intra-hippocampal infusion of JPK immediately after a weak training (a single pairing of a tone with a 1 s,.7 ma foot-shock) had no effect on auditory fear LTM (n = 15 for vehicle and n = 16 for JPK; H =.768, ANOVA on Ranks, p =.78)

Late-LTP induced by a single tetanic stimulation in combination with JPK is dependent on mrna translation. a) The facilitated L-LTP induced by a single tetanus in the presence of JPK (nm) was suppressed by anisomycin (Aniso 4 µm, at 18 min: 79 ± 12.7% for JPK and 17 ± 4.1% for JPK + Aniso, H = 9.6, p <.1). b) JPK ( nm) had no effect on the impaired L-LTP induced by four tetanic trains in the presence of anisomycin (4 µm, at 22 min: 27 ± 8.6% for Aniso and 33 ± 11.4% for JPK + Aniso, (1, 7) =.5, p =.945).

Western blots show that 3 min after systemic injection of A (2.5 mg/kg, i.p.) mtorc2-mediated phosphorylation of both Akt (Ser473) and PAK (Ser198/23) were increased in dorsal hippocampus (bottom left, n = 3 per group, t = 5.726, ** p <.1; bottom right, n = 3 per group, t = 8.263; ** p <.1).
