Synaptic Transmission Diagram - Neuroscience Education Resource #2007607 (License: Personal Use)

The image depicts a classic synaptic cleft where neurotransmitter-filled vesicles in the presynaptic terminal fuse with the membrane and release their contents into the synaptic space. These molecules then diffuse across and bind to specific receptor sites on the postsynaptic neuron, triggering downstream signaling. The grayscale design emphasizes structural clarity over realism, making it ideal for teaching core concepts in neurophysiology.
