Journal ArticleDOI
Role of Endogenous Cannabinoids in Synaptic Signaling
TL;DR: The synthetic pathways of endocannabinoids are discussed, along with the putative mechanisms of their release, uptake, and degradation, and the fine-grain anatomical distribution of the neuronal cannabinoid receptor CB1 is described in most brain areas, emphasizing its general presynaptic localization and role in controlling neurotransmitter release.
Journal ArticleDOI
Petilla terminology: nomenclature of features of GABAergic interneurons of the cerebral cortex

TL;DR: A representative group of researchers are convened to agree on a set of terms to describe the anatomical, physiological and molecular features of GABAergic interneurons of the cerebral cortex, and the resulting terminology might provide a stepping stone towards a future classification of these complex and heterogeneous cells.
Journal ArticleDOI
Presynaptically Located CB1 Cannabinoid Receptors Regulate GABA Release from Axon Terminals of Specific Hippocampal Interneurons
István Katona,Beáta Sperlágh,Attila Sik,Attila Käfalvi,E. Sylvester Vizi,Ken Mackie,Tamás F. Freund +6 more
TL;DR: The results suggest that cannabinoid-mediated modulation of hippocampal interneuron networks operate largely via presynaptic receptors on CCK-immunoreactive basket cell terminals, the likely mechanism by which both endogenous and exogenous CB1 ligands interfere with hippocampal network oscillations and associated cognitive functions.
Journal ArticleDOI
Differences between somatic and dendritic inhibition in the hippocampus
Richard B. Miles,Katalin Tóth,Katalin Tóth,Attila I. Gulyás,Attila I. Gulyás,Norbert Hájos,Tamás F. Freund +6 more
TL;DR: Hippocampal synaptic inhibition is mediated by distinct groups of inhibitory cells that may differentially control dendritic electrogenesis and axonal output of hippocampal pyramidal cells.
Journal ArticleDOI
Total number and distribution of inhibitory and excitatory synapses on hippocampal CA1 pyramidal cells
TL;DR: The results indicate that the highly convergent excitation arriving onto the distal dendrites of pyramidal cells is primarily controlled by proximally located inhibition and the organization of excitatory and inhibitory inputs in layers receiving Schaffer collateral input (radiatum/oriens) versus perforant path input (lacunosum-moleculare) is significantly different.
