Conditioned Place Preference and Aversion
The use of a virtual reality environment (VRE) enables behavioral scientists to create different spatial contexts in which human participants behave freely, while still confined to the laboratory. In this article, VRE was used to study conditioned place preference (CPP) and aversion (CPA). In Experiment 1, half of the participants were asked to visit a house for two minutes with consonant music...
متن کاملNicotine-induced conditioned place preference and conditioned place aversion in mice.
The motivational effects of nicotine were examined in mice using an unbiased place conditioning design. Swiss-Webster mice received four 15-min parings of a tactile stimulus with different doses of nicotine (0.25-2.0 mg/kg, IP). A different tactile stimulus was paired with saline injections. During conditioning, nicotine produced locomotor depression at the 2.0-mg/kg dose, with the greatest red...
متن کاملGABA Neurons of the VTA Drive Conditioned Place Aversion
Salient but aversive stimuli inhibit the majority of dopamine (DA) neurons in the ventral tegmental area (VTA) and cause conditioned place aversion (CPA). The cellular mechanism underlying DA neuron inhibition has not been investigated and the causal link to behavior remains elusive. Here, we show that GABA neurons of the VTA inhibit DA neurons through neurotransmission at GABA(A) receptors. We...
متن کاملGenetic background influences nicotine-induced conditioned place preference and place aversion in mice.
This study was designed to determine whether genetic differences influence the rewarding effects of nicotine in 4 inbred strains of mice (DBA/2, BALB/c, C3H, and C57BL/6). Nicotine (subcutaneous) induced a place preference in DBA/2 and BALB/c mice but a place aversion in C57BL/6 mice. A low dose of nicotine produced a significant place preference, whereas a high dose of nicotine produced place ...
متن کاملConditional Knockout of NMDA Receptors in Dopamine Neurons Prevents Nicotine-Conditioned Place Preference
Nicotine from smoking tobacco produces one of the most common forms of addictive behavior and has major societal and health consequences. It is known that nicotine triggers tobacco addiction by activating nicotine acetylcholine receptors (nAChRs) in the midbrain dopaminergic reward system, primarily via the ventral tegmental area. Heterogeneity of cell populations in the region has made it diff...
