Generate a detailed 2D-rendered visual of glial cells interacting with neurons. The glial cells should have soft pinkish and reddish tones, with some parts glowing subtly to indicate activity. The neurons should be light grey with soft blue highlights. Place the cells in a floating, open environment with a background that transitions from deep black to dark shades of purple or pink, using a smooth, blurred gradient effect. Ensure the cells are simple yet detailed, maintaining a clean and professional look. Subtle glowing elements should indicate neural activity between the cells, with the background providing a soft, abstract depth without overpowering the main visuals."
