Cocaine exhibits high liability for inducing addictive behaviors, but the mechanisms of neuroplasticity underlying the behavioral effects remain unclear. As a crucial mediator of neuroplasticity in diverse functional models, brain-derived neurotrophic factor (BDNF) could contribute to the mechanisms of addiction-related neuroplasticity. Here, we addressed(More)
Recent studies showed that dopamine or D1 receptor-selective agonists increased brain-derived neurotrophic factor (BDNF) mRNA and protein expression in neuronal cultures, and this action was blocked by SCH23390. Moreover, SKF38393 activated Trk receptors and downstream signaling in striatal neurons. This study examined whether dopamine agonists induce the(More)
The mesolimbic dopamine system plays a major role in psychostimulant-induced ultrasonic vocalization (USV) behavior in rodents. Within this system, psychostimulants elevate synaptic concentrations of dopamine thereby leading to exaggerated activation of postsynaptic dopamine receptors within the D1-like and D2-like subfamilies. Dopamine receptor stimulation(More)
