WebThis communication process is known as “neuronal firing.” When brain cells communicate frequently, the connection between them strengthens. Messages that travel the same pathway in the brain over & over begin to transmit faster & faster. With enough repetition, they become automatic. 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.
