WebNeurotransmitters are how we communicate between one cell and the next. Synapses between neurons are either excitatory or inhibitory – and that all comes down to the neurotransmitter released. Excitatory neurotransmitters cause the signal to propagate - more action potentials are triggered. Inhibitory signals work to cancel the signal.
