Environmental Screening of Aeromonas hydrophila, Mycobacterium spp., and Pseudocapillaria tomentosa in Zebrafish Systems

10.3K
This protocol describes the use of sump swabs and sludge analysis of zebrafish systems, which leads to increased detection compared to the sole use of sentinels to detect pathogens such as Aeromonas hydrophila, Mycobacterium spp., and Pseudocapillaria tomentosa. A system to monitor P. tomentosa eggs in quarantine is also...

Summary
This summary is machine-generated.

The brain uses shared object-based mechanisms for both attention and binocular rivalry, demonstrating how visual stimuli are selected for consciousness. This research clarifies how the brain prioritizes information, even when features change unpredictably.

Area of Science:

  • Cognitive Neuroscience
  • Psychology
  • Philosophy of Mind

Background:

  • The brain must select which sensory signals reach conscious awareness.
  • Binocular rivalry and attention are distinct visual selection processes.
  • Binocular rivalry causes alternating awareness; attention impairs ignored stimuli.

Purpose of the Study:

  • To investigate if attention and binocular rivalry share underlying selection mechanisms.
  • To determine if object-based selection is common to both attention and rivalry.

Main Methods:

  • Attention was cued to one of two superimposed transparent surfaces.
  • Rivalry was induced by presenting different images to each eye.
  • Object-based selection was isolated by excluding spatial, ocular, or feature-based cues.

Main Results:

  • Observers predominantly perceived the cued surface during rivalry.
  • Discrimination of uncued surface features was impaired.
  • Selection was object-based, not dependent on spatial, ocular, or feature properties.

Conclusions:

  • Attention and binocular rivalry utilize shared object-based selection mechanisms.
  • Attention can bias perceptual selection, leading to suppression in rivalry.
  • This highlights competition between object representations during perceptual selection.
