Fear Conditioning System

Product Code:46000

Fear conditioning is one of the most common methods to measure memory in rodents. It exploits the Pavlovian association between an unpleasant unconditioned stimulus (shock) to a conditioned neutral stimulus (sound cue). The reaction of rodents, as predated animals, is to freeze (stay immobile) when exposed to fearful situations, such as a shock.

Once the association has happened and the animal has memorized it, freezing will happen also when the sound is presented without shock. This is the principle of Fear Conditioning, which is also coupled to the change of the change context (appearance) to ensure that the animal is reacting to the association to the sound and not to the environment (cued and contextual fear conditioning)

Background

  • Fear conditioning is one of the most common methods to measure memory in rodents
  • It exploits the Pavlovian association between an unpleasant unconditioned stimulus (shock) to a conditioned neutral stimulus (sound cue or context)
  • The reaction of rodents, as predated animals, is to freeze (stay immobile) when exposed to fearful situations, such as a shock
  • The ratio between the freezing with and without shock gives a measure of the memorization of the event and hence allows for a fast memory screening

 Easy control, easy set up, easy expansion

The Ugo Basile system comes complete with:

  • Visible and IR lights
  • Ventilated isolation cubicle
  • Shocker and electrified cage
  • High intensity speaker for frequency and white noise sounds
  • IR camera, cables and lenses
  • Color-coded easy connections with the onboard electronics
  • Seamless to be expanded from 1 to 4 or more units for high throughput
  • Detection of the Freezing is automated through Any-maze or any other software, as well as the control of lights, sounds, shocker, etc.

If you're planning to track in multiple apparatus, or track for long periods (> 12 hours), or include large numbers (> 500) of animals in experiments then we recommend you read the whitepaper Choosing a computer for ANY-maze which discusses various technical considerations that you may need to take into

Fear conditioning is one of the most common methods to measure memory in rodents. It exploits the Pavlovian association between an unpleasant unconditioned stimulus (shock) to a conditioned neutral stimulus (sound cue or context). The reaction of rodents, as predated animals, is to freeze (stay immobile) when exposed to fearful situations, such as a shock, or to a neutral stimulus they have associated (i.e. they remember) to it.

Once the association has happened and the animal has memorized it, freezing will happen also when the sound is presented without shock or when the animal experiences the context where the shock was delivered.

This is the basic principle of Fear Conditioned, which is normally referred to as Cued and Contextual to describe change in the cage interior (context, or appearance). This step of the experiment ensures that the detected freezing is actually the reaction to the sound and not to the memory of the environment. In the same way, the memorization of the context as the unconditioned stimulus (with no sound used), can be measured by comparing the freezing with shock (training), or in the same context without shock.

One of the reasons of the success of Fear Conditioning in memory studies is indeed its simplicity and the fact that it can be frequently used as a single trial, fast and high-throughput experiment.
