Which one of the following statements about synaptic

Last updated: 7/25/2022

Which one of the following statements about synaptic function is incorrect? 1. If an excitatory synapse generated a 2 mV EPSP in a neuron's dendrite and an inhibitory synapse generated a 2 mV IPSP in a neuron's cell body, the inhibitory synapse would have a stronger influence on action potential generation in the postsynaptic cell. 2. If one applied a toxin to the presynaptic membrane that blocked the opening of voltage-gated K^+ channels, transmitter release would decrease. 3. At an excitatory synapse, binding of the neurotransmitter to its postsynaptic receptor generates net inward current across the postsynaptic membrane. 4. If one applied a toxin to the presynaptic membrane that blocked the opening of voltage-gated Ca^2+ channels, the amplitude of the postsynaptic potential would increase.
