This paper describes a simulation model of the MPP Pyramid  that has been constructed at the George Mason University. This model has been designed to facilitate experiments in processor control and in instruction set design.
The dopaminergic behavioral effects of apomorphine in rats were evaluated using a rating scale. Caerulein, a decapeptide physiologically similar to cholecystokinin, enhanced at lower doses and inhibited at higher doses the behaviors induced by apomorphine. Dibutyryl-cAMP, but not dibutyryl-cGMP, potentiated apomorphine behaviors. This potentiation was… (More)
