Principle of one-way conduction at chemical synapses 

always transmit the signals in one direction i.e., from the neuron that secretes the neurotransmitter called the presynaptic neuron, to the neuron on which the transmitter acts, called the postsynaptic neuron

Once an impulse reaches the presynaptic terminals, a response can be obtained in the postsynaptic neuron after a Synaptic delay.
