Effects of lithium chloride (LiCl) pretreatment on alterations in synaptic ultrastructure inside diverse subregions of your adult dorsal hippocampus (dHIP) induced by adolescent methamphetamine (METH) exposure. Representative electron micrographs from the CA1, CA3, and dentate gyrus (DG) of your tested mice; the straight arrows indicate Gray’s type-1 asymmetric synapses (excitatory synapses), whereas the curved arrows indicate the length with the presynaptic active zone; the boxes indicate regions shown at larger magnification in the decrease panels, and scale bars represent 500 nm beneath low magnification and one hundred nm beneath high magnification (A). Histograms show relative modifications in the total number of excitatory synapses, thickness of postsynaptic density (PSD) at the thickest aspect, width in the synaptic cleft, and length on the active zone in CA1 (B ), CA3 (F ), and DG (J ). Additional than 60 randomly chosen excitatory synapses from every single subregion were analyzed.
