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.

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. Drug-drug interactions DDIs occur when one drug alters the activity of another drug. Drug interactions may be both pharmacokinetic PK and pharmacodynamic PD in nature.

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.

Depletion of norepinephrine, but not serotonin, reduces long-term potentiation in the dentate gyrus of rat hippocampal slices. In addition, EEG signals were recorded using DC and a low-pass anti-aliasing filter, of Hz, at 20 kHz sampling rate, which has been shown to avoid saturation of amplifiers and minimize TMS-related artifact Rajji et al. PAS-induced potentiation of cortical-evoked activity in the dorsolateral prefrontal cortex. SI 1 mV, Stimulation intensity with a mean peak-to-peak motor evoked potential amplitude of 1 mV over 20 trials; SD, standard deviation. Given that these drugs are typically administered chronically, future studies should assess the effects of chronic administration. Contrary to our fourth hypothesis, we did not find a difference in PAS-induced LTP under baclofen compared to placebo. Agents for the treatment of cognitive disorders. Accepted : 29 October In animal and human brain slice studies, cholinergic activity plays a pivotal role in LTP facilitation in the prefrontal cortex Vidal and Changeux, Rights and permissions Reprints and permissions. Prefrontal cortex function, quasi-physiological stimuli and synaptic plasticity. Neuropsychopharmacology 36 , — While this is a limitation of several TMS-EEG protocols, the placebo arm in our study design would mitigate the impact of this confound. Effect of the acquisitionenhancing drug piracetam on rat cerebral energy metabolism.
