In view of the complexity of brain functioning, the study of the speed of thought production and taking into account that complex scientific problems have been solved through mathematical calculations or computational simulations, and also knowing that there is a consistent similarity between artificial neural networks with the brain which is formed by microscopic temporal spaces described by neural networks woven by synaptic connections of hundreds of millions of neurons and whose mathematical interpretation can be done only on a quantum scale; then we explain why the brain neural network simulation could be obtained through Neuroquantum Networks by using the quantum computer. We will comment about controversies between classical and quantum computing algorithms; about a possible simulation of the brain by means of a quantum computer whose algorithms must comply with the non-deterministic character of mathematics and principles of quantum physics. We detail in a simple way how quantum principles are applied in neurosciences.
