Acute pharmacological blockade of central histamine H3 receptors (H3Rs) enhances arousal/attention in rodents. However, there is little information available for other behavioral domains or for repeated administration using selective compounds. ABT-239 [4-(2-{2-[(2R)-2-methylpyrrolidinyl]ethyl}-benzofuran-5-yl)benzonitrile] exemplifies such a selective,(More)
RATIONALE Marijuana is known to have psychotropic effects in humans. In this study, we used rat models of sensorimotor gating, hyperactivity and stereotypy to explore whether CB(1) receptor stimulation or blockade induces behavioral changes consistent with psychotomimetic or antipsychotic agents, respectively. OBJECTIVES We determined whether (a) the(More)
International requirements for central nervous system (CNS) safety pharmacology are reviewed. Procedures for initial CNS safety screening (core battery studies) can be conducted from the beginning of the drug discovery process, but at latest before first studies in man. They should include assessment of general behaviour, locomotor activity and motor(More)
Among the numerous tasks designed for assessing distinct memory processes, the social recognition task in the rat offers the opportunity to evaluate a form of short-term working memory in the domain of social cognition, and its modification by pharmacological agents or physiopathological states, such as aging. Social cognition in humans is obviously of(More)
