まとめ
Semmes-Weinstein Monofilament Test(SWMT)中に閉眼することで、健常者の触覚感度が向上した。視覚入力は触覚評価に大きく影響し、体性感覚再教育における視覚操作の可能性を示唆している。
科学分野:
- 神経科学
- 感覚生理学
背景:
- Semmes-Weinstein Monofilament Test(SWMT)は、触覚を評価するための標準的なツールである。
- SWMTの結果に影響を与える要因を理解することは、正確な感覚評価にとって重要である。
研究 の 目的:
- 健常者において、開眼時、閉眼時、および騒音環境下でのSWMT値を比較すること。
- 触覚感度に対する視覚入力および聴覚妨害の影響を調査すること。
主な方法:
- 健常者70名を対象に、利き手および非利き手の指先でSWMTを実施した。
- 検査は、開眼時(スクリーンあり)、閉眼時、および騒音環境下(開眼時)で行われた。
- 各条件下での中央値SWMT値を記録した。
主要な成果:
- 騒音下および静寂下での検査環境におけるSWMT値に統計学的に有意な差は認められなかった。
- SWMTで測定された触覚感度は、利き手の親指において、開眼時と比較して閉眼時の方が有意に良好であった(p < 0.01)。
- 全ての検査部位で、全体の中央値SWMT値は一貫していた。
結論:
- 視覚遮断は、健常者の触覚検出を向上させる。
- 視覚入力は触覚評価において重要な役割を果たす。
- 視覚操作は、体性感覚再教育プログラムにおいて有用な方法となり得る。

Role of Affect in Interpersonal Attraction
220
Affect plays a crucial role in shaping interpersonal evaluations and perceptions. Emotions influence how individuals judge and respond to others, often determining whether interactions are viewed positively or negatively. This effect can manifest directly through interactions with the person in question or indirectly via associations with unrelated emotional experiences.Direct Effects of Affect on AttractionAffect directly influences interpersonal attraction when a person’s behavior...

Bioavailability Study Design: Healthy Subjects Versus Patients
146
Bioavailability studies are essential for evaluating a drug's therapeutic efficacy and understanding its absorption patterns under various physiological conditions. Conducting such studies on target patient populations provides more relevant data by simulating real-world disease states. However, practical challenges often necessitate the use of young, healthy adult volunteers as study subjects.Patients may exhibit altered drug absorption patterns due to the effects of the disease itself,...

Tactile and Chemical Senses
745
Tactile senses encompass touch, temperature, and pain, each mediated by specific receptors. Touch receptors detect mechanical energy or pressure against the skin. Sensory fibers from these receptors enter the spinal cord and relay information to the brain stem. Here, most fibers cross over to the opposite side of the brain. The touch information then moves to the thalamus, which projects a map of the body's surface onto the somatosensory areas of the parietal lobes in the cerebral cortex.

The Influence of Affect on Cognition
275
Positive affect significantly influences cognitive processes, including evaluation, memory, creativity, and social judgments. Compared to negative affect, positive emotional states promote more favorable interpretations of stimuli, cognitive flexibility, and heuristic processing. These effects highlight emotions' powerful role in shaping how individuals perceive, remember, and interact with the world.Influence on Evaluation and AttributionWhen individuals experience positive affect, they are...

The Influence of Cognition on Affect
196
Cognition plays a pivotal role in shaping emotional experiences, as demonstrated by Schachter and Singer’s two-factor theory of emotion. According to this model, emotion arises from a combination of physiological arousal and cognitive interpretation. The body’s physiological response to stimuli is ambiguous and only gains emotional significance through cognitive labeling. For instance, an increased heart rate and adrenaline surge while standing near an attractive person may be...

The Auditory Ossicles
3.1K
The auditory ossicles of the middle ear transmit sounds from the air as vibrations to the fluid-filled cochlea. The auditory ossicles consist of two malleus (hammer) bones, two incus (anvil) bones, and two stapes (stirrups), one on each side. These bones develop during the fetal stage and are the ones to ossify first. They are fully mature at birth and do not grow afterward.
The aptly named stapes look very much like a stirrup. The three ossicles are unique to mammals, and each plays a role in...
