This simple but powerful language allows us to harness the power of iteration to create realistic looking plant-like structures, as well as many other interesting fractals. Before we launch the Fractal Grower program, we'll look at the basic grammar of the L-System language. Let's examine the growth of an extremely simplified tree. #08********08 #] 21Nov2021 search "fractal models of neurons" >> TONS of stuff!! https://fractalfoundation.org/OFC/OFC-1-6.html Fractal Neurons [Search domain fractalfoundation.org] https://fractalfoundation.org › OFC › OFC-1-6.html It is the fractal branching pattern of the neuron's axons and dendrites that allows them to communicate with so many other cells. If neurons were shaped like cubes and neatly packed into the brain, one neuron could only connect with at most 6 other cells. Hippocampal neurons. Scale approximately 700 microns.

The road towards developing a full structuro-functional fractal model of neurons is certainly long and-as most geometrizations in natural sciences-probably uphill. https://pubmed.ncbi.nlm.nih.gov/11465996/ Use of fractal theory in neuroscience: methods, advantages ...

Fractal Neural Networks [Search domain fractal.org] www.fractal.org › Life-Science-Technology › Publications › Fractal-Neural-Networks.htm In principle all trajectories can be interpreted as symbolic representations of neurons . An iteration of a fractal algorithm will move us from z n to z (n+1). As well , a neuron at any point z n in a network could send its activity along its axon ( following the respective trajectory ) to the point z (n+1) of the neural network . #08********08 #] 12Nov2021 Fractal computing languages http://alvyray.com/Papers/CG/PlantsFractalsandFormalLanguages.pdf Plants, Fractals, and Formal Languages - Alvy Ray Smith [Search domain alvyray.com] alvyray.com › Papers › CG › PlantsFractalsandFormalLanguages.pdf It is based on an extension Of the well-known formal languages Of symbol strings to the lesser-known formal languages of labeled graphs.
