title: [Quantum mechanics and brain: a critical review].
abstract: OBJECTIVE
  Theories about consciousness are in an initial state of development. In the recent past, diverse theories have been proposed to explain the phenomenon of the consciousness using the Quantum Mechanics (QM) as a fundamental tool. Here, we criticize some of these theories in the light of the current knowledge in neuroscience.
  
  
  METHODS
  The QM theories of consciousness by John Eccles, Dana Zohar and Roger Penrose are discussed. For a better understanding of these theories, some physical principles of the quantum formalism are firstly introduced. We then expose these theories in the authors original formalism and discuss them from a neuroscientist point of view.
  
  
  CONCLUSIONS
  As currently exposed, the three QM theories of consciousness suffer from important neuroscientist concerns. It is not necessary the use QM to explain different aspects of brain function such as consciousness, which would be better understood using tools from the neurosciences
