- 神経学 神経学とは
- 病理学 パトロジー
背景:
- アルツハイマー病 (AD) や他の神経変性疾患の患者は,神経機能の重要な日々の変動を示します.
- これらの変動は,ニューロンの死または再生に起因するものではありません.
研究 の 目的:
- 神経退行性疾患で観察される毎日の変動について,新しい説明を提案する.
- これらの変異におけるニューラルネットワーク活動とタンパク質中毒の潜在的な役割を調査する.
主な方法:
- この研究は主に理論的であり,既存の臨床観察と神経変性疾患の病理学的理解に基づいています.
- ニューラルネットワークのダイナミクスと脳内のタンパク質の集積に関する現在の知識を統合しています.
主要な成果:
- 神経機能の毎日の変動は,ニューロン数の変化から生じる可能性は低い.
- これらの変異は,ニューラルネットワークの活動における動的変化と相関することがあります.
- 脳による有毒なタンパク質集積物の一時的なクリアランスまたは管理は,断続的な症状の改善を説明する可能性があります.

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.
Disorders of the Nervous Tissue
Nervous tissue is a vital component of the human body's communication system, enabling us to perceive and respond to stimuli. However, like all other tissues, it is vulnerable to disorders and diseases that can significantly impact our neurological functioning.

Photoreceptors and Visual Pathways
At the molecular level, visual signals trigger transformations in photopigment molecules, resulting in changes in the photoreceptor cell's membrane potential. The photon's energy level is denoted by its wavelength, with each specific wavelength of visible light associated with a distinct color. The spectral range of visible light, classified as electromagnetic radiation, spans from 380 to 720 nm. Electromagnetic radiation wavelengths exceeding 720 nm fall under the infrared category, whereas...
Alzheimer's Disease: Overview
Alzheimer's Disease (AD) is a continually advancing neurodegenerative disorder, distinguished by escalating memory loss, cognitive dysfunction, and dementia. The disease unfolds in three stages: preclinical, mild cognitive impairment (MCI), and dementia. Its onset is insidious, and the progression gradual, with the cause not well explained by other disorders.
The clinical diagnosis of AD hinges on the presence of memory and other cognitive impairments. Biomarkers, such as changes in Aβ and tau...

Neuroplasticity
Neuroplasticity reflects the brain's remarkable capacity to adapt and evolve, responding dynamically to learning, experiences, or injury by reorganizing its neural circuitry. This reorganization involves creating new neural connections and refining old ones through a series of biological processes that contribute to the brain's lifelong development and adaptability.
Prosopagnosia
Prosopagnosia, also known as face blindness, is the inability to recognize faces. In severe cases, individuals with prosopagnosia may not recognize close family members, including parents and spouses, by their faces. For instance, someone with prosopagnosia might walk past their child in a crowd, only realizing their mistake upon noticing their child's distinctive backpack or favorite jacket. Prosopagnosia specifically impairs facial recognition, while the recognition of other objects or...
