Synaptic weight and contribution as a function of synpapse size. A, Relationship between synaptic weight and synapse size (in square micrometers) according to Equation 5 (see Materials and Methods and Results). B, Comparison between the analytical expression derived to describe the size distribution of synapses (line) and the experimental data (bars) (Trommald and Hulleberg, 1997). C, Input contribution (synaptic weight multiplied by the fraction of synapses of that size) as a function of size.
