The mind is the set of cognitive processes related to perception, interpretation, imagination, memories, and crucially language (cf. There is consistent debate between the humanities and the sciences about the nature of the human mind and if and how it may be observed. The human brain is the source of the conscious, cognitive mind. Human consciousness is founded upon the extended capacity of the modern neocortex, as well as the greatly developed structures of the brain stem. Basic systems that alert humans to stimuli, sense events in the environment, and maintain homeostasis are similar to those of basic vertebrates. |work=Neuroscience for Kids|format=html] with a neocortex much larger than other animals, humans enjoy unique mental capacities despite having a neuroarchitecture similar to that of more primitive species. ![]() The neocortex accounts for about 76% of the mass of the human brain Cite web|url=|title=Questions and Answers|accessdate=|publisher=Eric H. ![]() This process was especially pronounced in the neocortex, a section of the brain involved with language and consciousness. Anatomically, the brain can be divided into three parts: the forebrain, midbrain, and hindbrain Cite web|url=|title=Brain Basics|accessdate=|publisher=About, Inc|author=Bailey, Regina|work=Human Anatomy and Biology|format=htm] the forebrain includes the several lobes of the cerebral cortex that control higher functions, while the mid- and hindbrain are more involved with unconscious, autonomic functions.During encephalization, human brain mass increased beyond that of other species relative to body mass.
