We hypothesized that increasing the dopaminergic tone with L-DOPA and the cholinergic tone with rivastigmine will enhance PAS-induced LTP, while increasing the GABAergic tone with baclofen and inhibiting glutamatergic neurotransmission with dextromethorphan will reduce it compared to placebo.

Long-term potentiation is widely used as a model for memory formation. Recently, much information concerning this topic like the involvement of protein kinase C, arachidonic acid and N -methyl- d -aspartate receptors has been reported. In this review recent discoveries concerning long-term potentiation and the pharmacological implications for the development of cognition-enhancing drugs are discussed.

Thus, future studies should assess the effects of chronic exposure to these medications in healthy individuals as well as patients with brain disorders associated with abnormalities in these neurochemical systems. Characteristic Mean SD Age years Bruce G, potentiation pharmacology.

This chapter describes and discusses the differentiation and quantitation of combined effects with respect to synergism or potentiation on the one hand, and antagonism on the other, in complex interactions. In the combinations considered here, the agents exhibit effects in the same direction, when tested singly. Hence, in binary mixtures, both compounds are active. These keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.

Pharmacodynamic drug-drug interactions DDIs occur when the pharmacological effect of one drug is altered by that of another drug in a combination regimen. DDIs often are classified as synergistic, additive, or antagonistic in nature, albeit these terms are frequently misused. Within a complex pathophysiological system, the mechanism of interaction may occur at the same target or through alternate pathways. Quantitative evaluation of pharmacodynamic DDIs by employing modeling and simulation approaches is needed to identify and optimize safe and effective combination therapy regimens. This review investigates the opportunities and challenges in pharmacodynamic DDI studies, and highlights examples of quantitative methods for evaluating pharmacodynamic DDIs, with a particular emphasis on the use of mechanism-based modeling and simulation in DDI studies. Advancements in both experimental and computational techniques will enable the application of better, model-informed assessments of pharmacodynamic DDIs in drug discovery, development, and therapeutics.

The pathway that is thought to be targeted by applying PAS to the DLPFC is a pathway that connects the somatosensory cortex to the prefrontal cortex as supported by neuroanatomical and neurophysiological studies in rodents Van Eden et al.
