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. Methods potentiation pharmacology In this randomized controlled, potentiation pharmacology, double-blind cross-over within-subject study, 12 healthy participants received five sessions of PAS to the DLPFC in a random order, each preceded by the administration of placebo or one of the four active drugs.

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.

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.

As complex diseases, especially cancer, are being treated with various drug cocktails, understanding the interactions among these drugs is increasingly vital to ensuring successful treatment regimens. However, the idea of synergy is not limited to only the biomedical realm and these ideas have developed across many different disciplines, as well. In this review, we first discuss the various terminology surrounding the idea of synergy, providing a comprehensive list of terms defined across numerous disciplines.

Finally, we did not use auditory masking to control for auditory artifacts due to several reasons. Woelk H. While this is a limitation of several TMS-EEG protocols, the placebo arm in our study design would mitigate the impact of this confound.
