Motor and Sensory Areas of the Cortex

2.9K
The cerebral cortex, the brain's outermost layer, is pivotal in processing complex cognitive tasks, emotions, and various sensory inputs and executing voluntary motor activities. This intricate structure is divided into three primary functional areas: the motor areas, sensory areas, and association areas.
Motor Areas
The motor areas located in the frontal lobe are central to controlling voluntary movements. This region is further subdivided into the primary motor cortex and the premotor...

Direct Motor Pathways

1.8K
The direct motor pathways, also known as the pyramidal tracts, are a group of neural pathways that originate in the brain and descend through the spinal cord. They control the voluntary movement of the body. There are two major direct motor pathways: the corticospinal and the corticobulbar tracts.
The corticospinal tract is responsible for the voluntary movement of the limbs and trunk. It originates in the cerebral cortex of the brain and descends through the cerebrum's internal capsule and...

  • 发动机控制器的控制器
  • 心理语言学 心理语言学

背景情况:

  • 在动力系统中否定动作的表现仍在争论中.
  • 目前尚不清楚否定的动作句子是否最初模拟了该动作.

研究的目的:

  • 为了调查运动系统激活的否定行为.
  • 在句子处理过程中探索皮质脊髓刺激性 (CSE) 和抑制性 (SICI).

主要方法:

  • 两项实验使用跨磁刺激来测量CSE和SICI.
  • 参与者阅读肯定和否定的行动/不行动句子.
  • 在动词呈现后的各种延迟时间进行了测量.

主要成果:

  • 采取行动的句子 (肯定和否定) 显示出更多的CSE比不采取行动的句子.
  • 与其他部分相比,CSE在肯定和否定行动句子中都增加了.
  • SICI在较长的延迟时增加,不管动词形式如何,对于否定的动作没有早期抑制.

结论:

  • 否定的动作似乎最初是在电机系统中模拟的.
  • 肯定和否定行为之间的早期神经差异可能起源于主要运动皮层之外.
