概括
在口服吞任务中,大脑区域的相互作用不同. 初级运动皮质 (M1) 驱动,而初级体感皮质 (S1) 引导舌头运动,突出了吞阶段的独特神经机制.
科学领域:
- 神经科学是一个神经科学.
- 发动机控制器的控制器
- 吞生理学的吞生理学
背景情况:
- 吞的口腔阶段涉及复杂的和舌头运动.
- 皮质控制对于启动和协调这些口腔阶段活动至关重要.
研究的目的:
- 调查口服吞过程中不同的神经机制和皮质相互作用.
- 为了比较模拟和舌头运动期间的大脑活动模式.
主要方法:
- 功能性磁共振成像 (fMRI) 用于25名健康成年人.
- 任务包括空口和舌头到部后部收缩.
- 动态因果建模和参数实证贝叶斯分析了有效的连接性.
主要成果:
- 在空过程中,主运动皮质 (M1) 是主要的输入,激发主体感官皮质 (S1) 和补充运动区域 (SMA).
- 在舌收缩过程中,S1成为主要输入,与M1和SMA的双向连接.
- 在舌头任务中,S1对SMA表现出抑制作用.
结论:
- 神经相互作用在口腔阶段的和舌头运动之间有所不同.
- M1-SMA相互作用对于口腔阶段至关重要;M1是的关键,S1是感官反的关键.
- 在舌头收缩期间,S1可能会抑制SMA,以促进吞并防止喉干扰.

Neural Regulation

Digestion begins with a cephalic phase that prepares the digestive system to receive food. When our brain processes visual or olfactory information about food, it triggers impulses in the cranial nerves innervating the salivary glands and stomach to prepare for food.

Motor and Sensory Areas of the Cortex
3.6K
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 cortex....

Cranial Nerves: Types Part II
2.0K
Cranial nerves are responsible for transmitting motor and sensory information between the brain and various parts of the body. There are twelve pairs of cranial nerves. While the first six innervate the head and neck, the latter six nerves innervate the head and neck, as well as organs and tissues in the thoracic and abdominal cavities. They facilitate communication, expression, and autonomic control within the human body.
