Super-resolution Fluorescence Microscopy01:37

Super-resolution Fluorescence Microscopy

14.8K
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...

Imaging Biological Samples with Optical Microscopy

12.2K
Optical microscopy uses optic principles to provide detailed images of samples. Antonie van Leeuwenhoek designed the first compound optical microscope in the 17th century to visualize blood cells, bacteria, and yeast cells. In 1830, Joseph Jackson Lister created an essentially modern light microscope. The 20th century saw the development of microscopes with enhanced magnification and resolution.
In optical microscopy, the specimen to be viewed is placed on a glass slide and clipped on the stage...

Difference from Background: Limit of Detection

8.9K
The limit of detection (LOD) is the smallest amount of analyte that can be distinguished from the background noise. The LOD value corresponds to the concentration at which the analyte signal is three times larger than the standard deviation of the blank signal. Below this value, the analyte signal cannot be differentiated from the background noise. It is calculated by dividing the calibration slope by 3 times the standard deviation of the blank signals.
The LOD indicates the presence or absence...

Phase Contrast and Differential Interference Contrast Microscopy

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...

Area of Science:

  • Cognitive Psychology
  • Neuroscience
  • Visual Perception

Background:

  • Figure-ground assignment is crucial for object recognition.
  • Figural regions are subjectively more salient than background regions.
  • The neural basis for figural salience remains incompletely understood.

Purpose of the Study:

  • To investigate whether figure-ground assignment enhances perceptual processing.
  • To differentiate between attentional and perceptual accounts of figural salience.
  • To examine the impact of figure-ground assignment on spatial resolution tasks.

Main Methods:

  • Observers performed a spatial resolution task with targets on figure, ground, or neutral regions.
  • Target discrimination was based on color (red/green) to control for attention.
  • Performance was measured by discrimination accuracy.

Main Results:

  • Targets on figures were discriminated more accurately than on grounds.
  • Targets on figures showed better discrimination than on neutral regions.
  • Targets on grounds showed poorer discrimination than on neutral regions.

Conclusions:

  • Figure-ground assignment perceptually enhances figural regions.
  • Ground regions are perceptually suppressed relative to figures and neutral regions.
  • These findings support enhanced perceptual processing as a consequence of figure-ground assignment.
