Supplementary Figure: Schematic view of synaptically activated Ca|*bsup*|2+|*esup*| sources in a GC spine.
A Local synaptic input from M/TC dendrite. Calcium entry via both VDCCs and NMDARs might trigger CICR.
B Global activation of the GC via a low-threshold spike evoked by synaptic activation of a sufficiently large set of other GC spines.
Question marks indicate hypothetical events, i.e. the activation of HVA VDCCs during local synaptic input and (2) release from the GC spine during either local synaptic activation or the global low-threshold spike. Ry-R: Ryanodine receptor.
