Biology on Instagram: "Neurons communicate. Synaptic transmission is the fundamental process by which nerve cells communicate with one another. This flow of information begins when an electrical impulse reaches the end of a presynaptic neuron, triggering the release of chemical messengers called neurotransmitters from synaptic vesicles into the tiny gap known as the synaptic cleft. These neurotransmitters then diffuse across the cleft and bind to specific receptors on the postsynaptic neuron. Th
