Resumen
Las células ganglionares de la retina intrínsecamente fotosensibles (ipRGC) son fotorreceptores recién descubiertos. Estudios recientes sugieren que los ipRGC influyen en la visión más allá de las funciones no formadoras de imágenes, impactando el contraste, el brillo y la percepción del color.
Área de la Ciencia:
- La neurociencia
- Oftalmología
- Ciencia de la visión
Sus antecedentes:
- Las células ganglionares de la retina intrínsecamente fotosensibles (ipRGC) se han relacionado tradicionalmente con las funciones visuales que no forman imágenes.
- La evidencia emergente sugiere que los ipRGC contribuyen a los procesos visuales de formación de imágenes.
Objetivo del estudio:
- Revisar el papel de las ipRGC en la percepción visual.
- Examinar críticamente los estudios sobre las funciones cognitivas y de formación de imágenes de los ipRGC.
Principales métodos:
- Revisión de la literatura de los estudios sobre las GCRPI.
- Análisis de las condiciones de investigación y resultados relacionados con la función ipRGC.
Principales resultados:
- Las ipRGC están involucradas en el procesamiento visual, incluyendo el contraste, el brillo y la percepción del color.
- Se destacan las lagunas en la investigación existente sobre las funciones cognitivas y de formación de imágenes de los ipRGC.
Conclusiones:
- Los ipRGC tienen un papel más significativo en el procesamiento visual de lo que se pensaba anteriormente.
- Se necesitan más estudios bien controlados para comprender plenamente las capacidades de formación de imágenes de los ipRGC.

01:32The Retina
70.5K
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.

7.6K
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...

01:22Photoreceptors and Visual Pathways
6.5K
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,...

01:24Vision
55.3K
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.

01:26Visual System

Light enters the eye through the cornea, a transparent, dome-shaped surface covering the surface of the eyeball that helps to direct and focus incoming light. This light is then channeled toward the pupil, an adjustable opening whose size is controlled by the iris. The iris, a pigmented muscle, regulates the amount of light entering the eye by contracting or dilating the pupil, thereby ensuring optimal light levels for clear vision.
Once through the pupil, the light passes through the lens, a...

Most organisms use photoreceptors to sense and respond to light. Examples of photoreceptors include bacteriorhodopsins and bacteriophytochromes in some bacteria, phytochromes in plants, and rhodopsins in the photoreceptor cells of the vertebral retina. The light-sensitive property of these receptors is because of the bound chromophores, such as bilin in the phytochromes and retinal in the rhodopsins.
Rhodopsins belong to the family of cell surface proteins called G-protein coupled receptors,...
