概括
重复的横磁刺激 (rTMS) 可以改变舌头的触觉敏度. 连续的甲突破刺激 (cTBS) 损害了空间感知,而间歇性的甲突破刺激 (iTBS) 改善了它,显示了对面腔感官调节的潜力.
科学领域:
- 神经科学是一个神经科学.
- 神经刺激是一种神经刺激.
- 感官感知是一种感官感知.
背景情况:
- 重复的横磁刺激 (rTMS) 调节体感皮层活动.
- 之前的rTMS研究集中在手/手指的表现上,忽视了面部系统.
- 耳脸系统的感觉感知和语音发音需要进一步研究rTMS的影响.
研究的目的:
- 为了研究连续爆刺激 (cTBS) 和间歇性爆刺激 (iTBS) 对舌头触觉敏度的影响.
- 为了比较cTBS,iTBS和假刺激对舌头感知空间和时间方面的影响.
- 探索使用甲爆刺激 (TBS) 调节面腔体感的潜力.
主要方法:
- 一个以15名志愿者为主题的设计.
- 四个实验性会议涉及cTBS,iTBS,假的,或没有刺激在左S1舌头表示.
- 使用定制的振动触觉刺激器评估舌头触觉敏度,以测量空间和时间歧视.
主要成果:
- 连续的甲爆刺激 (cTBS) 显著损害了空间振幅值,刺激后16-30分钟.
- 间歇性甲爆刺激 (iTBS) 在同一时间范围内显著改善了空间振幅值,尽管效果不如cTBS那么明显.
- 无论是cTBS还是iTBS都没有证明对时间歧视门的影响.
结论:
- 甲爆刺激 (TBS) 有效地调节耳面系统中的体感知觉.
- 调节面或面体体感觉对治疗触觉敏度缺陷有前途.
- 这项研究可以促进对语音产生中的感官系统的理解,并有助于语音运动学习和康复.

Somatosensation
36.5K
The somatosensory system relays sensory information from the skin, mucous membranes, limbs, and joints. Somatosensation is more familiarly known as the sense of touch. A typical somatosensory pathway includes three types of long neurons: primary, secondary, and tertiary. Primary neurons have cell bodies located near the spinal cord in groups of neurons called dorsal root ganglia. The sensory neurons of ganglia innervate designated areas of skin called dermatomes.

The Physiology of Taste
3.8K
The perception of a salty flavor is facilitated by sodium ions within the oral salivary fluid. Upon consumption of a salty substance, salt crystals disassemble, leading to the liberation of its constituents—Na+ and Cl- ions. These ions subsequently dissolve into the salivary fluid present in the oral cavity. The external environment of the gustatory cells experiences an elevation in Na+ concentration, thereby establishing a potent concentration gradient. This gradient propels the...

Somatosensory, Motor, and Association Cortex

The somatosensory cortex in the parietal lobes is crucial for interpreting sensory data such as touch, temperature, and proprioception. The somatosensory cortex, situated in the parietal lobes, plays a vital role in interpreting sensory information like touch, temperature, and proprioception—awareness of body position. This specialized brain region features an organized structure wherein neurons at the top primarily process sensations originating from the lower body. In contrast, those at...

Taste Buds and Receptors

Gustation, or the sense of taste, is intrinsically linked to the anatomical structures located on the tongue. This organ's surface, along with the entirety of the oral cavity, is adorned with stratified squamous epithelium. Evident on the tongue are elevated structures known as papillae (singular = papilla), which house the mechanisms for the transduction of gustatory stimuli. Four distinct types of papillae exist, each identified by their unique morphological attributes: the circumvallate,...
