GRIA1 and infection: These effects were not because of the transduction protocol since infection with empty virus had no effect on cLTP-induced GluA1/PSD-95 puncta increase at 1 h (t(56) = 2.41, p = 0.0099, one-tailed t test) or return to baseline at 24 h (t(33) = 0.9, p = 0.19, one-tailed t test) post-cLTP induction (Fig. 6C,D).
