Area of Science:

  • Neuroscience
  • Behavioral Neuroscience
  • Pharmacology

Background:

  • Acoustic startle response (ASR) and prepulse inhibition (PPI) are vital measures in neuroscience.
  • Changes in PPI are linked to psychiatric and neurological disorders, making it a key research area.
  • Existing commercial ASR/PPI systems are costly and lack transparency, hindering reproducibility.

Purpose of the Study:

  • To present a low-cost, flexible, and open-source software solution for ASR and PPI testing.
  • To provide a customizable Spike2-based interface for various PPI protocols.
  • To demonstrate the software's utility with experimental data from rat models.

Main Methods:

  • Development of a user-friendly, low-cost software for ASR/PPI testing using a Spike2 interface.
  • Implementation of a customizable Spike2 script supporting diverse PPI paradigms.
  • Acquisition of PPI data in female wild-type and dopamine transporter knockout (DAT-KO) rats.

Main Results:

  • The developed software successfully recorded ASR and PPI in rats.
  • Data showed reduced PPI in DAT-KO rats compared to wild-type controls.
  • Observed patterns in female rats mirrored those typically seen in males.

Conclusions:

  • The proposed software offers a cost-effective and reproducible alternative for ASR/PPI research.
  • This tool facilitates the study of neurological and psychiatric conditions associated with altered PPI.
  • The findings highlight the utility of the software in preclinical models, such as DAT-KO rats.
