Glutamate release and AMPA/NMDA receptor activation

Prompt used for this figure

Create a publication-ready Synaptic transmission diagram for Neuroscience, using the specific case: "Glutamate release and AMPA/NMDA receptor activation". The figure should be built around this concrete example, not a generic template. Clearly show the key entities, process steps, directional arrows, causal relationships, compartments or layers when relevant, and a concise legend. Use a clean scientific vector-illustration style, white background, restrained colors, accurate English labels, and a layout suitable for a journal Figure 1, methods figure, or graphical abstract. Additional rendering constraints: Do not add a large title, headline, caption, or any top-left title text. Do not include boxed legends, section headers, explanatory callout boxes, protocol paragraphs, or decorative background elements. Use only concise English labels attached directly to objects, arrows, axes, tracks, samples, tissues, molecules, or data marks. Build the figure around the specific case: "Glutamate release and AMPA/NMDA receptor activation". Keep the layout clean, readable, and suitable for direct use in a scientific web gallery. Use white background, restrained colors, crisp labels, clear visual hierarchy, and polished publication-ready scientific illustration or data-figure styling.
