Phase Contrast and Differential Interference Contrast Microscopy

9.4K
Phase-Contrast Microscopes
In-phase-contrast microscopes, interference between light directly passing through a cell and light refracted by cellular components is used to create high-contrast, high-resolution images without staining. It is the oldest and simplest type of microscope that creates an image by altering the wavelengths of light rays passing through the specimen. Altered wavelength paths are created using an annular stop in the condenser. The annular stop produces a hollow cone of...

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...

Three-Dimensional Microscopy in Microbiology

907
Three-dimensional imaging techniques are essential in cell biology, allowing researchers to visualize intricate cellular structures with high resolution. Two prominent methods, Differential Interference Contrast Microscopy (DIC) and Confocal Scanning Laser Microscopy (CSLM), provide distinct advantages for imaging live and thick specimens, respectively.Differential Interference Contrast MicroscopyDIC microscopy enhances contrast in transparent, unstained samples by converting phase...

Área de la Ciencia:

  • La neurociencia es la neurociencia.
  • La neurociencia de sistemas es la neurociencia de sistemas.
  • Los circuitos corticales son los circuitos corticales.

Sus antecedentes:

  • La corteza cerebral exhibe una arquitectura funcional organizada en columnas, con neuronas que comparten propiedades como la selectividad de orientación de estímulos.
  • Las técnicas de imágenes anteriores carecían de la resolución para determinar la precisión de estos mapas funcionales y sus fronteras.

Objetivo del estudio:

  • Investigar la organización a escala fina de los mapas funcionales en la corteza visual a una resolución de una sola célula.
  • Para resolver la precisión del ajuste neuronal y la estructura de los dominios funcionales.

Principales métodos:

  • Etiquetado in vivo de miles de neuronas de la corteza visual con un indicador sensible al calcio.
  • Microscopía de dos fotones de alta resolución para obtener imágenes de la actividad neuronal hasta 400 micrómetros de profundidad.

Principales resultados:

  • En la corteza visual primaria de la rata, se observó selectividad de orientación, pero no se observó una estructura local clara de las respuestas neuronales.
  • En la corteza visual del gato (área 18), las neuronas con preferencias de estímulo opuestas se segregaron con precisión en 3D, con límites de solo una o dos células de ancho.

Conclusiones:

  • Los mapas funcionales corticales se pueden organizar con precisión de una sola célula, desafiando las suposiciones anteriores basadas en técnicas de menor resolución.
  • La segregación precisa de la función neuronal sugiere un microcircuito altamente organizado en ciertas áreas corticales.
