Create diagrams (of the cells) and graphs (of the potentials) to illustrate the two different situations described below in a multipolar neuron with a threshold voltage of 15 mV above resting potential. In each, indicate decrement of graded potentials (by drawing the same GP at different points as it spreads along the neuron), as well as summation.
Situation 1: There are three simultaneously active synapses on the multipolar neuron, two producing EPSPs and one an IPSP. At least one of the EPSPs is larger than 15 mV at the synapse. The neuron does NOT generate an action potential.
Situation 2: There are two simultaneously active synapses, one producing an EPSP and the other an IPSP. The neuron generates an action potential.
