3D Model: A Realistic And Highly Detailed 3D Render Of A Group Of Interconnected Nerve Cells (neurons). The Neurons Should Have Clearly Visible Cell Bodies, Intricate Dendrites, And Long Axons. Emphasize The Synaptic Connections Between The Cells. The Overall Style Should Be A Scientific Visualization, With Subtle, Ethereal Glowing Elements Tracing The Neural Pathways To Represent Electrical Activity. The Background Should Be Dark To Contrast With The Bright Network. Highly Intricate, Biological Structure, Professional Visualization.
