What propey of the postsynaptic neuron would optimize the effectiveness of two closely spaced axodendritic synapses?: (A) A high membrane resistance, (B) A high dendritic cytoplasmic resistance, (C) A small cross-sectional area, (D) A small space constant
Answer is A. 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
