Generate a highly detailed, 3D render of brain cells (neurons) with a realistic color palette. Neurons should have soft beige and light pink tones for the cell body, with pale yellow axons extending outward. Dendrites should be light beige or off-white, forming delicate branches. Display synaptic connections in subtle pastel colors like pale blue, soft green, and gentle lavender to indicate activity. Use a clean, light background with a gradient from soft blue to white to keep the overall look soft and non-threatening. The style should be realistic, clean, and scientific, highlighting the natural beauty of neural structures in a non-intimidating way."
