English Prompts: Scene Composition: A timeline flow from left to right showing dendritic spine maturation. 1. Early Development: “Dendritic shaft with thin, finger-like filopodia extending towards presynaptic axonal terminals. Label: ‘Filopodia’.” 2. Maturation: “Filopodia contacting presynaptic terminals and morphing into mushroom-shaped dendritic spines. Stable connection formed. Label: ‘Spine Stabilization’.” 3. Physiological Pruning: “A ramified microglia (purple) extending a process to engulf a redundant, weak synapse. The microglia expresses GABA receptors on its surface. Label: ‘Synaptic Pruning’.” 4. Inhibitory Preference: “Zoom in on a somatic inhibitory synapse. Microglial process contacting the inhibitory synapse. DNA helix icon inside microglia nucleus indicating ‘GABA-initiated transcriptional program’.”
