Abstract:
:The influence of stressful experiences on the development of vacuous chewing movements (VCM) was investigated in non-medicated rats. After an initial baseline period one group of rats was housed in a noisy environment while another group was housed in quiet surroundings. The development of VCM was recorded during a 16 week period. The animals subjected to uncontrollable noise developed significantly more VCM compared with the control animals. The results are consistent with the idea that stress can sentize a behaviour which is usually connected with the nigrostriatal dopaminergic system. This underscores the essential role of the housing environment as a parameter during behavioural studies of the dopaminergic system, as for example studies of VCM in neuroleptic treated rats.
