- 认知神经科学是一种认知神经科学.
背景情况:
- 在儿童的后手术经常导致小脑损伤.
- 孤立小脑损伤对大脑网络和功能的影响尚不清楚.
- 有限的儿科神经成像数据存在于儿童后后腔手术后.
研究的目的:
- 为了研究小儿后手术后大脑功能网络的改变.
- 评估手术对运动和认知表现的影响.
- 探索神经成像发现与神经认知结果之间的关系.
主要方法:
- 对12名术后儿童和13名健康对照人进行横截面研究.
- 使用休息状态功能磁共振成像 (rs-fMRI) 进行脑部成像.
- 管理中枢神经系统生命体征 (CNS VS) 电池用于神经认知和运动评估.
主要成果:
- 手术后的儿童表现出较低的运动速度 (MotSpd),精神运动速度 (PsyMotSpd) 和神经认知指数 (NCI) 分数.
- rs-fMRI显示患者组皮质区域的区域活性增加和功能连接性改变.

Neuroplasticity
2.6K
Neuroplasticity reflects the brain's remarkable capacity to adapt and evolve, responding dynamically to learning, experiences, or injury by reorganizing its neural circuitry. This reorganization involves creating new neural connections and refining old ones through a series of biological processes that contribute to the brain's lifelong development and adaptability.

Role of Cerebellum and Prefrontal Cortex in Memory
1.5K
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...
