概括
与典型发育儿童 (TDC) 相比,患有单侧脑 (UCP) 的儿童表现出神经肌肉控制吞和说话的改变. 这些适应,包括肌肉活动的时间和协调,提供了潜在的治疗点.
科学领域:
- 神经科学是一个神经科学.
- 儿科 儿科 儿科
- 语音和听力科学 语言和听力科学
背景情况:
- 单侧脑 (UCP) 可以影响运动功能,包括吞和说话.
- 了解UCP中这些功能的神经肌肉控制对于干预至关重要.
- 在UCP中吞和说话的共享和独特的神经基础需要进一步调查.
研究的目的:
- 为了比较患有UCP的儿童与典型发育儿童 (TDC) 之间的吞和言语的神经肌肉控制.
- 在UCP中识别潜在的吞和言语的共同和独特的神经肌肉机制.
- 探索UCP儿童的神经肌肉控制和功能结果之间的相关性.
主要方法:
- 表面电肌图 (sEMG) 在吞和说话任务期间记录了脑下肌肉和口腔肌肉的肌肉活动.
- 关键变量包括正常化的平均振幅,到峰值振幅的时间和双边同步.
- 标准的临床测量评估了吞和语言表现.
主要成果:
- 患有UCP的孩子在任务中表现出更高的正常化平均幅度和比TDC更长的时间到峰值幅度.
- 与TDC相比,UCP组在吞过程中表现出双边同步性下降.
- 在UCP中,特定的神经肌肉模式与餐时间的持续时间相关,这表明功能联系.
结论:
- 患有UCP的儿童在吞和说话方面表现出明显的神经肌肉适应.
- 在这个人群中,在吞和发言之间存在共享和独立的神经肌肉控制机制.
- 这些发现突出了UCP治疗干预的潜在目标.

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.

2.1K
The brainstem, located inferior to the brain and superior to the spinal cord, serves as a bridge between the cerebrum and the spinal cord. It plays a vital role in relaying information and controlling critical life functions. It comprises three primary regions: the midbrain, pons, and medulla oblongata.
The Midbrain
The midbrain is located beneath the diencephalon and connects the cerebrum with the lower parts of the brain. The cerebral peduncles are prominent midbrain structures that house the...

Language is a system of communication that allows the expression of thoughts, ideas, and feelings. The brain processes language in both hemispheres.
Language formation and comprehension take place in the dominant hemisphere. The dominant hemisphere is responsible for understanding the meaning of spoken, written, or sign language, as well as the ability to communicate. For most people, the left hemisphere is the dominant one. The right hemisphere, then, gives tone and emotional context to the...
