 No thalamus, no pain
Dozens of studies, including those done at the University of San Francisco, show that although fetuses begin forming pain sensors during the 8th week of gestation, the thalamus is not formed until 20 weeks later. The thalamus is the part of the brain that routes information to other areas, and without it, no information can reach the cortex for processing.
I recognize that anti-choicers maintain other arguments, but the argument that 1st or 2nd trimester abortions cause suffering to sentient beings doesn't hold water.
At the third trimester, I would agree that's too late for an abortion.
