What propey of the postsynaptic neuron would optimize the effectiveness of two closely spaced axodendritic synapses?
A high membrane resistance
A high dendritic cytoplasmic resistance
A small cross-sectional area
A small space constant
Space constant increases with increasing membrane resistance or decreasing cytoplasmic resistance.Cytoplasmic resistance decreases as the cross-sectional area increases.Ref: Guyton; 13th edition; Chapter 46 Organization of the Nervous System, Basic Functions of Synapses, and Neurotransmitters
