original: At the end of the 20th century there was an emerging consensus among developmental neurobiologists that the establishment of thalamocortical connections (at about 26 weeks) is a critical event with regard to fetal perception of pain.
simplifications: At the end of the 20th century there was an agreement among neurobiologists that the creation of thalamocortical connections is a very important event for fetal perception of pain. There was a consensus among neuro-biologists at the end of the 20th century that the establishment of thalamocortical connections is a critical event to fetal perception of pain. Developmental neurologists mostly believe fetal pain begins around 26 weeks. This theory comes from the establishment of thalamocortical connections. These allow the brain to perceive pain. At the end of the 20th century, developmental neurobiologists began to agree that the establishment of thalamocortical connections (at about 26 weeks) is a critical event for pain perception in the fetus. At the end of the 20th century there was an new agreement among developmental neurobiologists that the establishment of thalamocortical connections (at about 26 weeks) is a critical event for fetal perception of pain. At the end of the 20th century developmental neurobiologists agreed that at 26 weeks a fetus could feel pain. At the end of the 1900s, more and more development neurobiologists agreed that the development of thalamocortical connections is an important part of a fetus's ability to feel pain. At the end of the 20th century, developmental neurobiologists agreed that fetus can feel pain at around 26 weeks due to the formation of the thalamocortical connections. There was a rapidly growing debate among developmental neurobiologists at the end of the 20th century that setting up thalamocortical ties (at about 26 weeks) is a serious event in terms of the fetal sense of pain. At the end of the 20th century, there was an agreement among developmental neurobiologists that the creation of thalamocortical connections (at about 26 weeks) is a critical event with regard to fetal perception of pain.
