True or False for each of the following: A. a neuronal synapse, facilitation of a post -synaptic response results because of an accumulation of calcium ions from previous pre-synaptic cell action potentials. B. In general, chemical synapses are limited because the signal they produce is “all-or-none” and cannot be significantly modified to reflect a difference in sensory. C. Temporal summation describes the cumulative EPSPs/ IPSPs generated in a post-synaptic cell through more than one synapse.
