Extended Data Fig. 4: Immunohistochemical verification of Grik4-Cre transgenic line.
From: Inhibitory control of sharp-wave ripple duration during learning in hippocampal recurrent networks
(a) Top left: Confocal image of FLEX-GCaMP8s expression when injected into CA3/CA2 of the Grik4-Cre transgenic line. Top right: CA2 pyramidal cells identified by their PCP4 immunosignal. Bottom: Merge of the above images. Note that GCaMP expression is largely confined to CA3 in the Grik4-Cre line, although some GCaMP8s-positive pyramidal cells in CA2 can be seen as well. This staining was repeated in n = 3 mice.
