Synaptic Cleft
The synaptic cleft is a minuscule gap separating two adjacent neurons and serves as a critical site for intercellular communication. When an electrical signal reaches the terminal buttons of an axon, synaptic vesicles release neurotransmitters into this space. These chemical messengers travel across the synaptic cleft and bind to corresponding, matching receptors on the dendrite of the adjacent neuron.

A specific neurotoxin is introduced into a neural pathway. Its sole effect is to prevent the structures at the very end of an axon from releasing their stored chemical messengers. What would be the most immediate and direct consequence of this toxin on the communication process between two connected neurons?
