Area of Science:

  • Neuroscience
  • Behavioral Science
  • Cognitive Science

Background:

  • Rodents are standard models for sensory, cognitive, and motor tasks.
  • Higher cognitive functions are typically studied in nonhuman primates due to complex behavioral requirements.
  • Rodent models offer a cost-effective alternative to primates for studying cognition.

Purpose of the Study:

  • To introduce an automated operant conditioning protocol for training rats on working memory tasks.
  • To adapt nonhuman primate experimental designs, specifically 'fixation' periods, for rodent models.
  • To demonstrate the protocol's utility in studying complex cognitive functions in rodents.

Main Methods:

  • Developed an automated operant conditioning protocol for rats.
  • Implemented a 'fixation' period requiring minimal movement until a Go cue.
  • Utilized a two-alternative forced choice task to assess performance.

Main Results:

  • Successfully operantly conditioned rats on a working memory task.
  • Demonstrated the feasibility of minimizing overt movement during critical task epochs.
  • Showcased the protocol's effectiveness in a two-alternative forced choice task.

Conclusions:

  • The developed protocol enables precise assessment of working memory in rats.
  • This method provides a cost-effective and automatable alternative to primate models for cognitive research.
  • The paradigm is adaptable for studying a broader range of complex cognitive functions in rodents.
