Area of Science:

  • Neuroscience
  • Philosophy of Mind
  • Medical Ethics

Context:

  • Current definitions of death are based on whole brain, brain stem, or neocortical formulations.
  • These existing models are insufficient for a comprehensive understanding of human death.
  • The study reviews and discusses these established formulations.

Purpose:

  • To propose a novel formulation of human death.
  • To base the new definition on the physiopathological mechanisms of consciousness generation.
  • To integrate the concepts of arousal and awareness into the definition of death.

Summary:

  • Consciousness generation involves complex interactions between the brain stem, diencephalon, and cerebral cortex.
  • Arousal and awareness are two critical physiological components of consciousness.
  • The proposed formulation posits consciousness as the paramount function, underpinning human attributes and integrated control.

Impact:

  • Offers a more holistic and integrated approach to defining death.
  • Highlights the crucial role of consciousness in defining human existence and organismal control.
  • Provides a new framework for discussions in neuroscience, ethics, and clinical practice regarding death determination.
