Something that can't feel pain isn't a suitable host for a human soul.

 

The first projections from the thalamus to cortex (the higher alarm) appear at 12-16 weeks' gestation. By this stage the brain's outer layer has split into an outer cortical rim, with a subplate developing below. The thalamic projections that develop from 12-16 weeks penetrate the subplate. Within the subplate, cortical afferents establish prolonged synaptic contacts before entering the cortical plate. The subplate is a โ€œwaiting compartment,โ€ required for mature connections in the cortex.6,7 The major afferent fibres (thalamocortical, basal forebrain, and corticocortical) can wait in the subplate for several weeks, before they penetrate and form synapses within the cortical plate from 23-25 weeks' gestation. Subsequent dissolution of the subplate occurs through prolonged growth and maturation of associative connections in the human cerebral cortex.
