Figures & data

Figure 1. Timeline of human brain development. This figure represents a schematized conceptualization of the steps during human brain development. Time in weeks post-conception and then postnatal years are shown along the horizontal axis. Birth and puberty and age at which cerebral cortex begins to thin are shown. The onset, peak, and end of different stages of neurodevelopment are depicted in color-coded fashion as shown in the associated table. “Days” in the figure refer to embryonic days. “Years” refer to postnatal years. The timing of the human stages is approximately based on refs 6, 117, 118, 119.
