概括
前视野 (FEF) 中持续的尖刺主要支持眼动准备,而不是空间工作记忆. 无活化研究显示FEF在眼睛运动中的缺陷,但没有记忆回忆.
科学领域:
- 神经科学是一个神经科学.
- 认知神经科学 认知神经科学
- 灵长类神经生理学
背景情况:
- 灵长类动物的背侧前额叶皮质的神经元,包括前额眼野 (FEF),在工作记忆任务中表现出持续的活动.
- 众所周知,FEF有助于眼运动和视觉空间注意力.

Association Areas of the Cortex
5.5K
Association areas are regions of the cerebral cortex that do not have a specific sensory or motor function. Instead, they integrate and interpret information from various sources to enable higher cognitive processes such as memory, learning, and decision-making. Some key association areas include the following:
Prefrontal Association Area: This area is located in the frontal lobe and is involved in planning, decision-making, and moderating social behavior. It connects with primary motor areas,...

Role of Cerebellum and Prefrontal Cortex in Memory
499
The cerebellum, while traditionally associated with motor control, also plays a crucial role in memory, particularly in procedural memory, which involves learning motor tasks that become automatic through repetition. For example, studies have shown that when the cerebellum is damaged, individuals or animals lose the ability to learn conditioned motor responses, such as the conditioned eye-blink response in classical conditioning experiments with rabbits. This study demonstrates the...
