- 神经学 神经学
- 认知科学 认知科学
背景情况:
- 空间疏忽是一种神经疾病,其特点是无法对空间的一侧的刺激做出反应.
- 这种综合症通常发生在一个大脑半球受损后,通常会影响空间的相反侧面.
研究的目的:
- 研究空间忽视现象,重点关注其潜在机制和半球不对称性.
- 探索人类大脑中语言和空间处理之间的关系及其对忽视的影响.
主要方法:
- 对单边脑损伤患者的临床观察和神经学发现的综述.
- 分析与空间疏忽相关的行为缺陷和病变位置.
主要成果:
- 在右半球损伤后的左侧疏忽比在人类左半球损伤后的右侧疏忽更频繁和严重.
- 这种功能不对称性在非人类灵长类动物中没有观察到.
- 脑部各个区域的损伤,包括头顶叶,头顶-头顶结节,皮质和前额叶皮质,以及皮质下结构,都可能导致忽视.
结论:
- 人类空间疏忽的横向不对称性可能归因于左半球对语言的专业化,可能削弱其空间处理能力.
- 虽然一些患者表现出认知功能的逆转,但语言和空间认知的全球逆转是罕见的.
- 侧面感官刺激为左侧和右侧忽视提供了暂时的改善.

Lateralization
294
Brain lateralization refers to the division of mental processes and functions between the two hemispheres of the brain, a phenomenon that optimizes neural efficiency and underpins complex abilities in humans. This specialization allows each hemisphere to perform tasks where it has a comparative advantage, facilitating more refined cognitive capabilities across different domains.

Cerebral Hemispheres
266
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...

Prosopagnosia
122
Prosopagnosia, also known as face blindness, is the inability to recognize faces. In severe cases, individuals with prosopagnosia may not recognize close family members, including parents and spouses, by their faces. For instance, someone with prosopagnosia might walk past their child in a crowd, only realizing their mistake upon noticing their child's distinctive backpack or favorite jacket. Prosopagnosia specifically impairs facial recognition, while the recognition of other objects or...
