虽然人类父母适应性的大脑特征有很好的记录，但与适应不良相关的大脑皮层特征却没有得到充分的研究。我们调查了一小组忽视孩子的母亲（忽视组24人，NG）与对照组非忽视孩子的母亲（对照组21人，CG）的皮质厚度和表面积是否不同。我们还测试了皮质差异是否与母子情绪可用性（EA）在与他们的孩子玩任务，是否述情障碍涉及低情绪意识的特点NG可以发挥作用，在皮质EA协会。全脑分析的皮质外套确定减少皮质厚度在右额中回和增加表面积在右舌和枕叶外侧皮质NG相对于CG。随访路径分析表明，右额中回（RMFG）的情绪可用性（EA）和识别的困难（述情障碍因素）的直接影响，边际间接RMFG-EA效果通过这个因素。这些初步研究结果扩展了现有的工作，暗示与疏忽养育和母子互动的债券相关的皮质功能的差异。
Although the brain signatures of adaptive human parenting are well documented, the cortical features associated with maladaptive caregiving are underexplored. We investigated whether cortical thickness and surface area vary in a small group of mothers who had neglected their children (24 in the neglect group, NG) compared to a control group of mothers with non-neglectful caregiving (21 in the control group, CG). We also tested whether the cortical differences were related to dyadic mother-child emotional availability (EA) in a play task with their children and whether alexithymia involving low emotional awareness that characterizes the NG could play a role in the cortical-EA associations. Whole-brain analysis of the cortical mantle identified reduced cortical thickness in the right rostral middle frontal gyrus and an increased surface area in the right lingual and lateral occipital cortices for the NG with respect to the CG. Follow-up path analysis showed direct effects of the right rostral middle frontal gyrus (RMFG) on the emotional availability (EA) and on the difficulty to identify feelings (alexithymia factor), with a marginal indirect RMFG-EA effect through this factor. These preliminary findings extend existing work by implicating differences in cortical features associated with neglectful parenting and relevant to mother-child interactive bonding.
