During pregnancy, maternal brain neuroplasticity indicates vast neurofunctional and neuroanatomical changes. Recent findings documented a similarly massive readjustment after pregnancy. Currently, these brain changes are interpreted as preparation for and adjustment of the maternal brain to motherhood. Yet, this perspective leaves many questions unsolved. Neuroscientific studies have not yet been conducted to determine the brain areas that function during natural childbirth even though physiological birth is the natural process of women who have reproduced successfully throughout two million years of evolution of the genus Homo. It is rational to believe that the female brain is an active and crucial actor during birth and that birth, itself, is a process that requires brain neuroplasticity. Lack of studies of the birthing brain and brain preparation for birth is a significant lacuna in neuroscience research. I demonstrate theoretically that a new hypothesis for complementary interpretation of maternal brain neuroplasticity is reasonable: Certain maternal brain changes during pregnancy can be interpreted asbrain preparation for birth and certain maternal brain changes after birth can be interpreted asbrain recovery after the tremendous event of birth. This essay can be a starting point for new directions in neuroscience studies.
在妊娠期间,母体大脑的神经可塑性表明其具有广泛的神经功能和神经解剖学变化。最近的研究发现,产后也会发生类似的大规模调整。目前,这些大脑变化被解释为母体大脑为母性做准备和适应的过程。然而,这种观点仍有许多未解之谜。尽管生理性分娩是女性在 200 万年人类进化过程中成功生育的自然过程,但神经科学研究尚未进行以确定自然分娩期间起作用的大脑区域。有理由相信,在分娩过程中,女性大脑是一个活跃且至关重要的参与者,而分娩本身就是一个需要大脑神经可塑性的过程。对分娩大脑和分娩前大脑准备的研究不足,是神经科学研究中的一个重大空白。我从理论上证明,一个用于补充解释母体大脑神经可塑性的新假设是合理的:妊娠期间母体大脑的某些变化可以解释为分娩准备,而产后母体大脑的某些变化可以解释为分娩这一巨大事件后的大脑恢复。本文可以为神经科学研究的新方向提供一个起点。
