They thought that neurons are processors having some internal data processing. Neurons are only cells having different characteristics than other cells. These differences are not so dramatic that we should suppose that neurons work like integrators. In spite of that, it seems to be very clear that most deductions can be correct. Differential equations describe movement.
Integration is the basic operation that is used to solve differential equations.
The human brain must be able to solve integration using neural structures. Neurons are cells that are similar to other cells. Differences between neurons and other cells are not very substantial. These seven statements express the controversy between neural structures in the brain and integration. To begin with, we must understand the term movement in an extended sense, meaning that the movement of the body includes also the movement of all substances in the body the fluids and structures of the body.
