This research was designed to study sexual differences in place conditioning induced by morphine in offspring born of female Wistar rats mated with drug-naïve males. Mothers were exposed to morphine during the 14th-16th days of gestational. Control dams were simply saline-injected. Female and male virgin offspring born of morphine-treated or saline-treated mothers were separately housed until b...
We recorded hippocampal place cells in two spatial environments: a training environment in which rats underwent fear conditioning and a neutral control environment. Fear conditioning caused many place cells to alter (or remap) their preferred firing locations in the training environment, whereas most cells remained stable in the control environment. This finding indicates that aversive reinforc...
Prior studies using mice have shown that scent marks are an important source of information and can cause behavioural changes in other individuals. Studies have also shown that scent marks in the environment can affect the outcome of social interactions between mice. We used conditioned place preference tests to investigate whether CD-1 male mice (Mus musculus) are reinforced by olfactory cues ...
background: cuminum cyminum fruit essential oil (feo) dose-dependently can attenuate the expression of morphine tolerance and dependence in morphine-dependent mice. objective: in this study, the effects of cuminum cyminum feo on acquisition and expression of morphine-induced conditioned place preference (cpp) in morphine-sensitized mice were studied. methods: repeated subcutaneous (s.c.) admini...
Using the place conditioning paradigm (biased design), we have shown that five conditioning sessions with ethanol (0.5 or 1.0 g/kg i.p.) did not result in place conditioning response. In contrast, rats that received 20 injections of ethanol (0.5 g/kg) or saline, before the conditioning procedure, showed significant place preference to the compartment paired with 0.5 g/kg ethanol (but not 1.0 g/...

This article describes the proceedings of a symposium at the 2001 RSA annual meeting in Montreal, Quebec, Canada. The cochairs were Fred O. Risinger and Christopher L. Cunningham. Presentations were as follows: (1) Place conditioning: understanding the motivational impact of stimuli, by Rick A. Bevins; (2) Role of historical factors in ethanol place conditioning, by Frank A. Holloway; (3) Ethan...
