When one neuron-alien wants to “talk” to the next alien, it reaches its arm out and gives the tiniest of shocks on the toe of the next alien. (These particular aliens show friendship by giving tiny shocks to one another. Weird, I know.)
Neurons communicate with each other by sending impules/electric shocks to other neurons. The impulses arise from the axon, go across the synapse, and touch the dendritic spines.
