Study this diagram carefully and read the additional information below it before answering this question: This diagram shows a neuron (tan) with two excitatory inputs (E1 and E2) and two inhibitory inputs (I1 and I2). Imagine that the following conditions exist simultaneously: E1 conducts 10 action potentials to its axon terminal per second E2 conducts 40 action potentials to its axon terminal per second I1 conducts 15 action potentials to its axon terminal per second I2 conducts 50 action potentials to its axon terminal per second Now, with all this information in mind, answer this quesiton: Which input will produce the biggest (greatest magnitude) EPSP?
