New encounter with Synaptotagmin

I was reading the very recommended and engaging book "The Self-Assembling Brain" , from professor Peter Robin Hiesinger. My surprise was Synaptotagmin is mentioned, as an example of the exact point of the book: let's focus and see brain development, from a genetic code perspective, as an algorithmic growth and evolutionary programming, with sthocastic and deterministic factors. Brain connectivity robustness is a result of such a proccess.

Synaptotagmin, presynaptic molecule that sense and regulates calcium, and is expressed at a point after the first brain wiring is developed (very important fact: one can trust a little more in knock-out studies in this case). From a high level point of view, synaptotagmin receives electrical signals and converts in chemical signals.
