“…A. Schematic illustration shows how the neuronal progenitors change shape and directionduring neurodevelopment. This illustration is related to our previous study4 , in which we designed how cell shape, direction, and electrical activity are defined as independent elements for neurodevelopment. The 3D position of cells in beginning= {𝑖, 𝐽 ̂, 𝑘 ̂}, the G function and its parameters as The change in position of cells = {d𝑝 1 , d𝑝 2 , d𝑝 3 }, Shapes= Sphere, ellipsoid, pyramidal approximation, other convex bodies, Electrical activity= Excitatory {+}, Inhibitory {−}, Excitatory/Inhibitory {±}, X (𝑑𝑝 1 , s, 𝑒 1 ), Y (𝑑𝑝 2 , s, 𝑒 2 ), Z (𝑑𝑝 3 , s, 𝑒 3 ).…”
