まとめ
自由に動き回るネズミのネズミの目動きは,他の哺乳類と異なり,捕食者の検出のために,連続した双眼の並べ替えではなく,頭上の重複する視野を優先します.
科学分野:
- 神経科学は神経科学である.
- 比較生理学とは
- ビジョン ビジョン 科学 科学
背景:
- 精密な眼球の整合は,哺乳類の双眼融合に不可欠であり,頭部運動中に反射によって維持されます.
- ネズミは目の動きを制御する重要な要素を持っているが,自由運動中の彼らの協調性は特徴づけられていない.
研究 の 目的:
- 自由に動き回るネズミの眼球運動の調整を調査する.
- ネズミが移動中に連続した双眼直線を維持しているかどうかを判断するために.
主な方法:
- 探索中に自由に動くネズミの目の動きを記録する.
- 行動反応を評価するために,上頭と横の視覚的刺激を提示する.
主要な成果:
- ネズミの眼球の動きは,他の哺乳類と根本的に異なるもので,連続した双眼直線を維持していない.
- 目の動きは,ネズミの上の視野の連続的な重なりを保証し,正確な並べ替えではありません.
- 上の視覚刺激は,横の刺激とは異なり,即座に避難場所を探す行動を誘発した.
結論:
- ネズミの目の動きは,潜在的な捕食者を検出するための頭上の視野を維持することを優先します.
- この戦略は盲点を最小限に抑え,上空からの脅威のある環境での生存を向上させます.
- ネズミの視覚系は,他の哺乳類と比較して,捕食者の監視のための明確なメカニズムを進化させた可能性があります.

The Retina
56.6K
The retina is a layer of nervous tissue at the back of the eye that transduces light into neural signals. This process, called phototransduction, is carried out by rod and cone photoreceptor cells in the back of the retina.

Vision
48.6K
Vision is the result of light being detected and transduced into neural signals by the retina of the eye. This information is then further analyzed and interpreted by the brain. First, light enters the front of the eye and is focused by the cornea and lens onto the retina—a thin sheet of neural tissue lining the back of the eye. Because of refraction through the convex lens of the eye, images are projected onto the retina upside-down and reversed.

Super-resolution Fluorescence Microscopy
12.3K
Super-resolution fluorescence microscopy (SRFM) provides a better resolution than conventional fluorescence microscopy by reducing the point spread function (PSF). PSF is the light intensity distribution from a point that causes it to appear blurred. Due to PSF, each fluorescing point appears bigger than its actual size, and it is the PSF interference of nearby fluorophores that causes the blurred image. Various approaches to achieving higher resolution through SRFM have recently been...

Association Areas of the Cortex
10.2K
Association areas are regions of the cerebral cortex that do not have a specific sensory or motor function. Instead, they integrate and interpret information from various sources to enable higher cognitive processes such as memory, learning, and decision-making. Some key association areas include the following:
Prefrontal Association Area: This area is located in the frontal lobe and is involved in planning, decision-making, and moderating social behavior. It connects with primary motor areas,...

Anatomy of the Eyeball
8.6K
The eye is a spherical, hollow structure composed of three tissue layers. The outer layer — the fibrous tunic, comprises the sclera — a white structure — and the cornea, which is transparent. The sclera encompasses some of the ocular surface, most of which is not visible. However, the 'white of the eye' is distinctively visible in humans compared to other species. The cornea, a clear covering at the front of the eye, enables light penetration. The eye's middle...

Perceptual Constancy
1.8K
Perceptual constancy is the ability to recognize that objects remain consistent and unchanged even when their appearance varies due to changes in sensory input. There are four main types of perceptual constancy: size constancy, shape constancy, color constancy, and brightness constancy.
Size constancy is the recognition that an object remains the same size, even when its image on the retina changes. For instance, a bus is perceived to be large enough to carry people, even if it looks tiny from...
