Real life fractals! In the beautiful sketches of brain cells and brain anatomy by Santiago Ramon y Cajal at the MIT Museum I noticed one with an eerie resemblance to the Mandelbrot set. Others were also clearly fractal, at least up to a point.  The sketch of Astrocytes particularly struck me — is there a known math fractal with this appearance, a cross between a star and a fern?

How hard would it be to write a fractal generator to emulate this beautiful natural phenomenon? Perhaps one might start with the "fern" fractal....

Yes, brain fractals are amazing! There has definitely been research along the lines of modelling neurons with fractals. The two most common techniques are L-systems and Diffusion Limited Aggregation

Here is an application using L-systems: http://krasnow1.gmu.edu/cn3/L-Neuron/index.htm
And here is a research paper using DLA: https://www.semanticscholar.org/paper/Spatial-embedding-of-neuronal-trees-modeled-by-Luczak/3019c5bb61182b3b9cb1a5d750b5e83bc4e6a904
