Figure 4. Quantitative comparison Met-ir in identified profiles in the neuropil of the stratum radiatum of CA1 in dorsal hippocampus.

Figure 4

A. At P7 (black bars), P14 (striped bars) and P21 (grey bars) significant differences in the distribution of Met-labeled profiles were revealed across the three ages (P7 versus P14, p < 0.001, d.f. = 4, χ2; P7 versus P21, p < 0.001, d.f. = 4, χ2; P14 versus P21, p < 0.001, d.f. = 4, χ2) B. Graph illustrating the increase in the proportion of presynaptic to postsynaptic profiles from near equivalence at P7 and P14 to predominantly presynaptic at P21. Error bars represent standard error of the mean, N = 3 in each group.
