In turn, the cfs branch longitudinally and make contact with the dendrites of clusters of PCs. Thus, perhaps the most striking aspect inside the cerebellar microcircuit is the fact that, whilst mfs, cfs, GoC axons and Pc dendrites are oriented longitudinally, they’re orthogonal for the pfs that cross the Pc dendritic trees.Mesoscale OrganizationBeyond the combinatorial and geometrical architecture described above, that is valid for the entire cerebellar cortex, you will discover larger orders of organization.The Inhibitory Interneuron Networks The cerebellum is characterized by two extended inhibitory interneuron networks. The GCL layer inhibitory network is made of feedforward and feedback loops driven by mfs: (i) the mfs excite GrC and GoC dendrites and these latter inhibit GrCs inside a feedforward loop, and (ii) the mfs excite GrCs after which pfs excite GoCs and these latter inhibit GrCs within a feedback loop (Sim s de Souza and De Schutter, 2011; Mapelli et al., 2014). The GoCs are interconnected by way of gap-junctions and reciprocal inhibitory synapses. The ML inhibitory network is formed by a series of MLIs (SCs and BCs) activated by pfs and inhibiting PCs in feed-forward (Santamaria et al., 2002, 2007). The MLIs are interconnected by way of gap-junctions and reciprocal inhibitory synapses (Astori et al., 2009; Alcami and Marty, 2013).Cortical Microzones and Cerebellar Modules Tracing studies have revealed longitudinal zones that elongate within the rostro-caudal direction and run perpendicular towards the extended axis on the lobules. The longitudinal zones contain the olivocerebellar afferents (cfs) and the corticonuclear (Pc) efferents. The somatotopic distribution of cfs are directed to 1 or two longitudinal zones, whilst mfs have a more extended transverse branching and terminate in various longitudinal zones. Some longitudinal zones can be split into smaller sized units named microzones. The microzones getting the same cf inputs from the multizonal microcomplexes and are essential for the parallel processing and integration of information coming from mf inputs. Hence, though the neocortex is characterized by microcolums and columns, the cerebellum is often divided into anatomo-functional modules deriving from the assembly of microzones (Cerminara, 2010). Recently, by combining in vitro recordings with optogenetics, it has been possible to determine stereotyped patterns of functional synaptic organization betweenFrontiers in Cellular Cephradine (monohydrate) custom synthesis Neuroscience | www.frontiersin.orgJuly 2016 | Volume 10 | ArticleD’Angelo et al.Cerebellum ModelingFIGURE 1 | The multi-level organization from the cerebellum.
