Psychosurgery

51
Psychosurgery, the surgical alteration or permanent removal of brain tissue to alleviate severe psychological conditions, stands as one of the most radical and controversial treatments in the history of mental health care. Its development and application have evolved significantly, marked by dramatic shifts in scientific understanding and ethical perspectives.
Historical Development of Psychosurgery
In the 1930s, Portuguese neurologist Antonio Egas Moniz introduced a surgical procedure designed...

Cerebral Hemispheres

308
The human brain, a complex organ, is functionally divided into two cerebral hemispheres—left and right. These hemispheres are interconnected by a structure of paramount importance, the corpus callosum. This substantial bundle of neural fibers is not just a bridge between the hemispheres but a crucial element for the brain's comprehensive functioning. It enables efficient communication between the two hemispheres, allowing each side of the brain to control and receive sensory and motor...

科学领域:

  • 神经科学是一个神经科学.
  • 神经外科 神经外科
  • 儿科神经学 儿科神经学

背景情况:

  • 半球切除术是一种成功的手术,用于扩散的单半球病变.
  • 手术后的神经可塑性及其与半球切除术后行为恢复的联系尚不清楚.

研究的目的:

  • 在左半球或右半球切除术后调查灰质体积 (GMV) 变化.
  • 分析GMV变化与行为恢复之间的关系.
  • 探索术前成像对术后结果的预测价值.

主要方法:

  • 儿科患者手术前和后的GMV比较 (29左半球切除,28右半球切除).
  • 使用2115名健康儿童的规范建模来推导年龄调整的GMV.
  • 与行为评分相关的GMV变化.

主要成果:

  • 两组都显示在对侧大脑和小脑侧侧脑部的GMV增加.
  • 两组人都表现出对侧小脑的GMV下降.
  • 左半球切除术患者独特地显示GMV在逆侧环状回形中减少.
  • 与右半球切割患者的行为改善相关的逆侧小脑GMV降低.
  • 在手术前的GMV预测了两组手术后的行为评分.

结论:

  • 神经可塑性,特别是在对侧小脑中,在右半球切除术后的行为恢复中起作用.
  • 术前脑成像可以预测儿科半球切割患者的术后行为结果.
