Depends on the synapse, and the proximity of the synapse to the soma of
the postsynaptic cell (as well as the geometry of the dendrite it's on),
not how close it is to the presynaptic cell.
Case in point: synaptic efficacy of Betz cells in the motor cortex on
motor neurons in the caudal spinal cord, a metre away.
