Wave dynamics provide a better explanation of brain function. Moving away from brain theories based on functionally specialized cell populations connected by a complex array of axons.

Geometric constraints on human brain function - Nature

Cortical and subcortical activity can be parsimoniously understood as resulting from excitations of fundamental, resonant modes of the brain’s geometry rather than from modes of complex interregional connectivity.

@ekmiller Could it be that the apparent simplicity of brain function determined by its shape is partly due to electric field influencing function? Electric field has speed of light influence, and decreases in strength with distance. Just wondering...
