A detailed behavioral analysis during the first postoperative week was performed in rats which had sustained various degrees of unilateral neostriatal dopamine (DA) lesions by administration of the neurotoxin 6-hydroxydopamine ...

A video image analyzing system is presented which measures turning behavior, thigmotactic scanning and locomotion in rats. The system works by analyzing digitized video images obtained by a black/white video camera. Turning ...

Introduction. St. John’s wort (Hypericum perforatum, HP) is one of the most used herbal medicines. Here we investigated the putative antidepressive- and anxiolytic-like effects of HP, by using a well-validated rat model ...

The analysis of behavioral asymmetries is a widely employed approach to investigate behavior in relation to functions of the brain. Out of the repertory of presently available measures, turning behavior is probably the one ...

Asymmetries in turning and scanning were investigated in rats with different degrees of neostriatal dopamine depletion after unilateral injections of 6-hydroxydopamine into the substantia nigra. Animals with severe lesions, ...

1. Rats which had received a unilateral injection of 6-OHDA into the substantia nigra were assigned to four lesion groups according to the degree of DA depletion in the neostriatum. In these animals, behavioral changes in ...

Although aging and environmental stimulation are well-known to affect cognitive abilities, the question of whether aging effects can be distinguished in already-mature adult rats has not been fully addressed. In the ...

Psychosocial stress is capable of causing immune dysregulation and increased neuroinflammatory signaling by repeated activation of the neuroendocrine and autonomic systems that may contribute to the development of anxiety ...
