Result 10 3.1 Early life stress model with limited bedding and behavior validation. 10 3.2 ELS affects mild anxiety-like behavior, particularly LD box test in adults. 10 3.3 ELS had no effect on the number of MCs. 11 3.4 ELS had no effect on the exonal projection pattern of MCs. 11 3.5 ELS suppresses the expression of the MCs neurotransmitter, GluR2/3. 12 3.6 ELS reduced the cell activity of MCs and GCs. 12 3.7 ELS impaired rapid context discrimination. 13 IV.
