Increases in both striatal dopamine release and the proportion of the D2 receptors in the high affinity state (D) accompany the behavioral sensitization to psychostimulants, but it is not known whether the physiological substrate of the interindividu

Depression is strongly related to social behavior. We have previously shown that social behavior of rats is individually stable. The purpose of the present study was to compare the sensitivity of animals with different sociability to chronic variable

Manipulation of juvenile rats in a way that mimics the rough-and-tumble play and resembles tickling elicits 50-kHz ultrasonic vocalizations (USVs) that have been proposed as a measure of positive affect. In the present experiments the stability of th

Individual differences in novelty-related behavior are associated with sensitivity to various neurochemical manipulations. In the present study the amphetamine-induced locomotor activity and behavioral sensitization to amphetamine (0.5 mg/kg) was inv

Behaviour in novel environments is influenced by the conflicting motivators fear and curiosity. Because changes in both of these motivational processes are often simultaneously involved in human affective disorders, we have developed the exploration

Social behaviour is the basis of one of the most generally accepted independent dimensions of personality. The purpose of the present study was to find out whether the social activity of individual rats, expressed in the social interaction test of an

Corticotropin-releasing factor (CRF) holds a central role in reactions to various environmental stimuli. In the present study, the administration of a selective nonpeptide CRF(1) receptor antagonist, CP-154,526, for 6 days, exerted an anxiolytic effe

It has been proposed that lesions of the ascending noradrenergic projections render animals more vulnerable to stress. In this study, the effects of partial denervation of the locus coeruleus (LC) by DSP-4 (10 mg/kg) treatment, chronic mild stress (C

Pretreatment with DSP-4, a neurotoxin highly selective for the locus coeruleus (LC) noradrenergic projections, 2 weeks before in vivo microdialysis in conscious rats had no effect on baseline extracellular dopamine (DA) levels in the nucleus accumben

Pretreatment with N-2-chloroethyl-N-ethyl-2-bromobenzylamine (DSP-4), a neurotoxin highly selective for the locus coeruleus (LC) projections, has recently been found to increase the vulnerability of dopaminergic nerve terminals to their selective neu
