Figure 5. Axon extension in gray matter across early ages.

Dorsal views depict representative axon extension in 15 cortices across the different developmental ages included in this study. For this figure, the three tangential substrates that make up the conventional rodent gray matter (subplate, infracortical fasciculus, cortex) are collapsed into one compartment. The abbreviations below each animal indicate the thalamic areas in which anterograde and/or retrograde labeling was noted. Abbreviations: dorsal lateral geniculate nucleus, dLGN; ventrobasal nucleus, VB; ventrolateral nucleus, VL.
