Make it more difficult for excitatory inputs to produce a post-synaptic potential large enough to trigger APs

Make it easier for excitatory inputs to produce a post-synaptic potential large enough to trigger APs

Trigger the activation of the Na⁺/K⁺ ATPase ion pump

Trigger the opening of Na⁺ ion channels

To leave unaltered the probability of excitatory inputs producing a post-synaptic potential large enough to trigger APs
