Interneurons can be connected by both electrical and chemical synapses, but the organization and interaction of these two complementary microcircuits is unknown. By recording from multiple molecular layer interneurons in the cerebellar cortex, we reveal specific, nonrandom connectivity patterns in both GABAergic chemical and electrical interneuron networks. Both networks contain clustered motifs and show specific overlap between them. Chemical connections exhibit a preference for transitive patterns, such as feedforward triplet motifs. This structured connectivity is supported by a characteristic spatial organization: transitivity of chemical connectivity is directed vertically in the sagittal plane, and electrical synapses appear strictly confined to the sagittal plane. The specific, highly structured connectivity rules suggest that these motifs are essential for the function of the cerebellar network. date: 2014-02-19 official_url: http://dx.doi.org/10.1016/j.neuron.2013.12.029 vfaculties: VGHCSCI oa_status: green full_text_type: pub language: eng primo: open primo_central: open_green article_type_text: Journal Article, Research Support, Non-U.S. Gov't verified: verified_manual elements_source: PubMed elements_id: 932509 doi: 10.1016/j.neuron.2013.12.029 pii: S0896-6273(13)01190-2 lyricists_name: Hausser, Michael lyricists_name: Roth, Arnd lyricists_id: MHAUS91 lyricists_id: AROTH52 full_text_status: public publication: Neuron volume: 81 number: 4 pagerange: 913 - 929 event_location: United States issn: 0896-6273 citation: Rieubland, S; Roth, A; Häusser, M; (2014) Structured connectivity in cerebellar inhibitory networks.
