Review session friday, s1-3 from 7-9, monday same day. Post-synaptic neuron will fire as long as both inputs, which are excitatory, fire simultaneously or close enough to depolarize to an. Any of the excitatory pre-synaptic neurons is sufficient to trigger an action potential in the post- synaptic neuron. Abro gate/inhibitory logic gate (also called an only/non- Post-synaptic neuron will fire only if the excitatory input fires alone. If the inhibitory input is on, either alone or in conjunction to the excitatory input, post-synaptic neuron does not fire. Inverts the default signaling mode of the post-synaptic neuron: excitatory input will toggle the normally inactive post-synaptic neuron ( off ) to an on state, whereas an inhibitory input will toggle a normally on neuron to its off state. The inverse of an and gate, meaning that the summation of the action of the inputs will toggle a normally on neuron to an.
