Behavioural effects of psychostimulant and opiate drugs are mediated in part by cAMP pathways operating in the nucleus accumbens. Degradation of cAMP occurs through the action of phosphodiesterases, such as the Type IV phosphodiesterases (PDE4s) that are found throughout the brain. To examine the potential role of PDE4 in reward-mediated behaviour, we(More)
Songbirds are important animal models for studying neural mechanisms underlying learning and memory. While evidence has emerged that cAMP plays a significant role in invertebrate and mammalian learning, little is known about the role of cAMP pathways in regulating neuronal function in birds. With the goal of identifying important components of this pathway,(More)
