Brain Architecture and Skills are Built in a Hierarchical “Bottom-Up”

Sequence• Neural circuits that process basic information

are wired earlier than those that process more

complex information.

• Higher circuits build on lower circuits, and

skill development at higher levels is more

difficult if lower level circuits are not wired

properly.
