title: Individually housed rats exceed group-housed animals in rotational movements when exposed to a novel environment.
abstract: Individually and group-housed rats of both sexes were compared in respect to spontaneous rotational movements when exposed to a novel environment. Thereby, individually housed animals showed a higher number of rotational movements than group-housed controls. During an L12:D12 cycle, such movements occurred most frequently at the beginning of the dark phase, when locomotor activity was highest. It is assumed that these rotations are part of the hyperreactivity toward a novel environment induced by long-term individual housing.
