Imaging Biological Samples with Optical Microscopy01:18

Imaging Biological Samples with Optical Microscopy

7.5K
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...

Positron Emission Tomography01:29

Positron Emission Tomography

6.1K
Positron emission tomography (PET) is a medical imaging technique involving radiopharmaceuticals — substances that emit short-lived radiation. Although the first PET scanner was introduced in 1961, it took 15 more years before radiopharmaceuticals were combined with the technique and revolutionized its potential.
One of the main requirements of a PET scan is a positron-emitting radioisotope, which is produced in a cyclotron and then attached to a substance used by the part of the body...

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...

Negative Regulator Molecules

Positive regulators allow a cell to advance through cell cycle checkpoints. Negative regulators have an equally important role as they terminate a cell’s progression through the cell cycle—or pause it—until the cell meets specific criteria.

Area of Science:

  • Affective science
  • Psychology
  • Neuroscience

Background:

  • Affective research frequently utilizes visual stimuli to investigate defensive responses.
  • The International Affective Picture System (IAPS) is a common resource, but has limitations in discrete emotional categories.
  • A need exists for a more comprehensive image set for studying fear and disgust.

Purpose of the Study:

  • To develop and validate a novel image set, the Open Biological Negative Image Set (OBNIS).
  • To provide researchers with a diverse collection of negative visual stimuli for affective research.
  • To categorize images based on disgust, fear, and neutral emotional responses.

Main Methods:

  • Developed the Open Biological Negative Image Set (OBNIS) with 200 color and grayscale creature images.
  • Conducted two experiments with participants rating image valence, arousal, disgust, and fear.
  • Categorized images into 'disgusting,' 'fearful,' and 'neither' based on participant responses.

Main Results:

  • The OBNIS contains 200 images with associated valence, arousal, disgust, and fear ratings.
  • Images are classified into 'disgusting,' 'fearful,' and 'neutral' categories.
  • The dataset is publicly available for download.

Conclusions:

  • The OBNIS is a valuable, validated resource for affective science research.
  • This image set addresses the limitations of existing resources for studying negative emotions.
  • OBNIS facilitates research on defensive mechanisms and emotional processing.
