Thank you very much for the lesson in the neurological aspect of the development of an unborn child.steen said:The spinal cord ends up in the brain stem which connects tho the thalamus and then through the thalamocortical tract connects with the brain's cortes. The input enters in the cortex of the parietal lobe (top middle/back), gets processed into sensation and responses are then generated by the "motor strip" (top middle/front). The final connection of the thalamocortical tract to the cortex of the parietal lobe occurs at the end of the 26th week of pregnancy.
Not much. Without input, there is no evaluation or conscious response, only reflexes. The brain does no more processing than a computer that is turned off. Once signals reach the parietal lobe, processing begins. (Only exception are cranial nerves I and II that are not going through the brainstem/thalamus "switchboard.")
However, what does this have to do with the fact that a human unborn child has been permitted to escape the abortionists vacuum cleaner or butcher's tools for the first six months of its life? It still has a third of the way to go and, as we all know, in the US, a zygote has only one chance in three in exiting the birth canal alive.
Please spare me the philosophical discussion about brain-waves, sentience, and the rest of the factually unsupported nonsense about how while all occupants of the womb are living humans, some are persons and some are non-persons who have no rights, especially the right to continue to live.
