The Nervous System II: Synaptic Potentials and Cellular Integration1. Enhanced postsynaptic potentials are due to increased _______ entering the terminal as a result of ____________________________________. 2. Presynaptic inhibition is due to decreased _______ entering the terminal as a result of ____________________________________. 3. a. Synaptic potentials are also known as ______________ potentials. b. They _____________ as they travel away from the synapse. 4. a. Increasing the number of action potentials on an axon in a given period of time would cause __________________________ summation. b. Increasing the number of synapses from different neurons would cause __________________ summation. 5. The magnitude of the EPSPs may be reduced (thus affecting their ability to
