Perceptron: Let's break down thinking into calculations

Perceptron is the most fundamental model of how the brain thinks. Fundamental in the sense that it is the most minimum function that is at least required to perform brain like thinking. Thinking can also be thought of as a calculation and calculation is best described in terms of functions. I described perceptron as the most fundamental model which also means it is the most minimum form of function that is at least required for brain-like thinking to perform. If we go even below this the full functionality of the brain will not be possible.
