Silencing giant interneurons and thereby exciting medium spiny neurons during cocaine-induced activity disrupts cocaine reward.
Indeed, Macey et al. show that, following both 5 and 30 days of self-administration of cocaine, functional activity in the dorsal and ventral striatum was significantly reduced.
Cocaine-mediated behaviors in the 129S1 strain have not yet been reported; however, several other 129 substrains have been characterized for cocaine locomotor activity with mixed results [ 21, 25, 27- 29].
Mr. Londoño, 52, who uses the aliases Timochenko and Timoleón Jiménez, is considered one of the FARC's leading intelligence operatives and a mastermind of its cocaine trafficking activities.
Consistent with previous observations [10], [11], WT and NR1DATCre mice showed a significant and progressive increase in cocaine-induced activity (Fig. 7A, two way RM-ANOVA, days, F2, 26 = 14.849, p<0.001), and again, no statistical differences were observed between genotypes (two way RM-ANOVA, genotypes, F1,26 = 0.211, p = 0.654).
Although it is known that cocaine induced locomotor activity is initiated in the VTA, not much is known about the electrical activity in real time.
The findings suggest that state dependent effects may alter sexual motivation and that repeated exposure to cocaine during sexual activity may increase sexual motivation which, in turn, may lead to high risk sexual activities.
In two experimental protocols, we measured the effects of cocaine on locomotor activity and grooming behavior, and subsequently tested whether these cocaine effects became conditioned to contextual cues.
Bogart also mentioned that if the price of cocaine rises, illegal activity to support that rise could also increase.
A subset of mice was tested further to determine cocaine induced locomotor activity.
Mice remained in the open field chambers for 30 min following cocaine and locomotor activity was recorded.
