Relations between the action potential frequency and the number of active synapses in two compartments and between the energy consumption of integrating each bit of information and the number of active synapses in two compartments. The horizontal axis and vertical axis indicate the number of active synapses in each compartment. (A,B) The change in the frequency and the energy consumption when the synapses on distal basal dendrites and distal truck become active. (C,D) The change when the synapses on distal basal dendrites and medial truck branch become active. (E,F) The change when the synapses on prolonged trunk and distal truck branch become active. (G,H) The change when the synapses on proximal trunk branch and distal tuft become active.
