Circuit model of the granular layer representing a one-dimensional array of single-compartmental granule cells (grcs) and Golgi cells (Gocs). This paper examines the effects of feedback inhibition (grc -> Goc -> grc) versus feedforward inhibition (mossy fibre -> Goc -> grc) on synchronization and oscillatory behaviour.

// Morphology file for Golgi cell
// A single compartment neuron with a spherical soma yielding
// an Rin (78 MegaOhm) and a time-constant (24 msec) as tabulated in Midtgaard (1992).
// The resulting Cm is 0.31 nF, assuming a specific membrane capacitance of 0.01 (F/m^2).
// The resulting surface area is 0.31e5 um^2.
// Written by RM (27/11/95).
