Depression of neuronal excitability and epileptic activities by group II metabotropic glutamate receptors in the medial entorhinal cortex.
Article in Hippocampus, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Whereas the ionotropic glutamate receptors are the major mediator in glutamatergic transmission, the metabotropic glutamate receptors (mGluRs) usually play a modulatory role. Whereas the entorhinal cortex (EC) is an essential structure involved in the generation and propagation of epilepsy, the roles and mechanisms of mGluRs in epilepsy in the EC have not been determined. Here, we studied the effects of activation of group II metabotropic glutamate receptors (mGluRs II) on epileptiform activity induced by picrotoxin or deprivation of extracellular Mg2+ and neuronal excitability in the medial EC. We found that activation of mGluRs II by application of the selective agonist, LY354740, exerted robust inhibition on epileptiform activity. LY354740 hyperpolarized entorhinal neurons via activation of a K+ conductance and inhibition of a Na+ -permeable channel. LY354740-induced hyperpolarization was G protein-dependent, but independent of adenylyl cyclase and protein kinase A. However, the function of Gβγ was involved in mGluRs II-mediated depression of both neuronal excitability and epileptiform activity. Our results provide a novel cellular mechanism to explain the antiepileptic effects of mGluRs II in the treatment of epilepsy.
