Imagine a cell receives both excitatory and inhibitory input and has
a threshold 15mV above Vrest. Activation of either type of synapse alone results in a PSP of 1mV (either a 1mV EPSP, or 1mV IPSP) at the synapse, and activation of 2 excitatory or 2 inhibitory synapses together results in a composite PSP of 2mV. Synapses on the dendrites are located 1 λ from the soma/trigger zone.
QUESTION: How much would the membrane potential change at the trigger zone, if a motor neuron receives 50 excitatory inputs on its dendrites, and 10 inhibitory inputs on the trigger zone? I.e., what is the combined effects of these inputs? (FILL IN THE BLANK)
