ABSTRACT

In research facilities that are registered with the U.S. Department of Agriculture (USDA), funded by the Public Health Service, or accredited by the Association for the Assessment and Accreditation of Laboratory Animal Care (AAALAC) International, the Institutional Animal Care and Use Committee (IACUC) is charged with oversight and evaluation of animal care and use under the terms of the Animal Welfare Act and the Guide for the Care and Use of Laboratory Animals. Although the committee's oversight of investigator compliance may be evaluated annually during USDA inspections and triennially during AAALAC International site visits, routinely assessing the quality and effectiveness of the IACUC's performance is difficult. To measure the successfulness of IACUC oversight, our committee retained a management consultant to objectively design and conduct a confidential survey that could be used to determine how the IACUC could improve the process of facilitating researcher compliance with federal regulations and accreditation standards. The consultant based the content of the survey on confidential interviews with all IACUC members, the IACUC administrator, and a cross sectional representation of the key animal-user population at the facility. The survey was then distributed to the entire animal-user population. Vice-presidents, directors, principal investigators, and technicians were included in the distribution. With a response rate of 34%, the survey results indicated that the facilitation process warranted refinements. The consultant provided the IACUC with its recommendations, which were based on the discernible trending information indicated in the survey responses. The IACUC developed a specific plan of action to address the consultant's recommendations and intends to re-survey the animal-user population once the action plan has been fully implemented. In summary, the survey is an excellent way to assess the quality and effectiveness of IACUC oversight in investigator compliance by determining the level of researcher satisfaction. The evaluation, review, and follow-up process using a confidential interview and questionnaire technique can enhance the performance and effectiveness of IACUC oversight.

ABSTRACT

The present research used a startle amplitude reduction paradigm to investigate the ability of the rat's auditory system to track rapidly changing acoustic transients. Specifically examined was the ability of brief gaps in otherwise continuous noise to reduce the amplitude of a subsequently elicited acoustic startle reflex. The duration of the gap, time between gap offset and startle elicitation (the interstimulus interval or ISI), and rise-fall characteristics of the gap were systematically varied. Consistent with previous research, gaps reliably reduced startle amplitude. Gaps 2 msec long were reliably detected, and a 50-msec ISI resulted in the greatest amplitude reduction. Gaps presented at short ISIs produced amplitude reduction that followed a different time course than did gaps presented at longer ISIs. These results may reflect differences in the length of time available for the processing of the stimulus and may involve two different processes.
