Sort the phrases into the appropriate bins depending on which type of postsynaptic potential they describe. if a phrase describes both types of potentials, drag it to the "both" bin.

Excitatory postsynaptic possibilities (EPSPs) are excitatory in light of the fact that they make the postsynaptic neuron more prone to produce an activity potential by depolarizing the layer (making the film potential less negative) and conveying the layer potential more like an edge. This is regularly expert by opening ligand-gated Na+ diverts in the postsynaptic layer, which enables Na+ particles to enter the cell. 
Interestingly, inhibitory postsynaptic possibilities (IPSPs) make it more troublesome for the postsynaptic neuron to create an activity potential by hyperpolarizing the layer (making the film potential more negative) and moving the film potential more distant from the limit. This is frequently proficient by opening ligand-gated K+ directs in the postsynaptic layer, which enables K+ particles to leave the cell. 
Despite whether they are excitatory or inhibitory, all postsynaptic possibilities are reviewed, implying that their sizes are variable. (Activity possibilities, then again, are all-or-none occasions.) And on the grounds that a postsynaptic potential is not proliferated like an activity potential, its greatness diminishes with separation from the neurotransmitter along the cell body.
