Maternal separation followed by isolation-housing differentially affects prepulse inhibition of the acoustic startle response in C57BL/6 mice

Exposure to chronic stress is associated with an increased incidence of neuropsychiatric dysfunction. The current study evaluated two competing hypotheses, the cumulative stress and the match/mismatch hypothesis of neuropsychiatric dysfunction, using two paradigms relating to exposure to “stress”: pre-weaning maternal separation and post-weaning isolation-housing. C57BL/6 offspring were reared under four conditions: typical animal facility rearing (AFR, control), early handling (EH, daily 15 min separation from dam), maternal separation (MS, daily 4 hr separation from dam), and maternal and peer separation (MPS, daily 4 hr separation from dam and from littermates). After weaning, mice were either housed socially (2–3/cage) or in isolation (1/cage) and then tested for prepulse inhibition in adulthood. Isolation-housed MPS subjects displayed greater deficits in prepulse inhibition relative to socially-housed MPS subjects while socially-housed AFR subjects displayed greater deficits in prepulse inhibition relative to isolation-housed AFR subjects. The results indicate that these treatment conditions represent a potentially valuable model for evaluating the match/mismatch hypothesis in regards to neuropsychiatric dysfunction.

Mountains of the world - Sustainable development in mountain areas: The need for adequate policies and instruments

This brochure deals with policies and policy instruments needed to promote sustainable development in mountain areas. The first part presents an overview of key issues in mountain development, and principles and strategies that should be adopted. Each principle contains a checklist for policy-makers. The second part presents national and regional case studies of successful approaches and initiatives relating to mountain policy from all over the world. The brochure concludes with a call for multi-level initiatives and partnerships. This full-colour publication is part of the Mountains of the World series. It was prepared for the 2002 World Summit on Sustainable Development in Johannesburg by an international panel of experts coordinated by CDE. It was commissioned and funded by the Swiss Agency for Development and Cooperation (SDC).
