Figure 3: LTP induction in the medial perforant path—dentate gyrus (MPP-DG) pathway in sensorimotor deprived group (treatment) and sham-operated control group (control) at indicated age. (a) PN25, (b) PN35, (c) PN45, (d) PN60. Arrow indicates the time point when conditioning stimulation was administered. Numbers of rats ( ) and slices ( ) are indicated in all figures. (e) Summary of LTP induction at PN25, PN35, PN45, and PN60. a highly significant between group difference for a given age ( ).
