Julian Jaynes was an American psychologist at Yale and Princeton for nearly 25 years, best known for his 1976 book The Origin of Consciousness in the Breakdown of the Bicameral Mind. His career was dedicated to the problem of consciousness: "the difference between what others see of us and our sense of our inner selves and the deep feelings that sustain it. ... Men have been conscious of the problem of consciousness almost since consciousness began." Jaynes's solution touches on many disciplines, including neuroscience, linguistics, psychology, archeology, history, religion and analysis of ancient texts.
The Origin of Consciousness in the Breakdown of the Bicameral Mind is a 1976 book by the Princeton psychologist, psychohistorian and consciousness theorist Julian Jaynes (1920-1997). It explores the nature of consciousness – particularly "the ability to introspect" – and its evolution in ancient human history. Jaynes proposes that consciousness is a learned behavior rooted in language and culture rather than being innate. He distinguishes consciousness from sensory awareness and cognition. Jaynes introduces the concept of the "bicameral mind", a non-conscious mentality prevalent in early humans that relied on auditory hallucinations.
McLean Hospital is a psychiatric hospital in Belmont, Massachusetts. McLean maintains the world's largest neuroscientific and psychiatric research program in a private hospital. It is the largest psychiatric facility of Harvard Medical School, an affiliate of Massachusetts General Hospital, and part of Mass General Brigham, which also includes Brigham and Women's Hospital.
The American Psychiatric Association (APA) is the main professional organization of psychiatrists and trainee psychiatrists in the United States, and the largest psychiatric organization in the world. It has more than 38,000 members who are involved in psychiatric practice, research, and academia representing a diverse population of patients in more than 100 countries. The association publishes various journals and pamphlets, as well as the Diagnostic and Statistical Manual of Mental Disorders (DSM). The DSM codifies psychiatric conditions and is used mostly in the United States as a guide for diagnosing mental disorders.
Bicameral mentality is a hypothesis introduced by Julian Jaynes who argued human ancestors as late as the ancient Greeks did not consider emotions and desires as stemming from their own minds but as the consequences of actions of gods external to themselves. The theory posits that the human mind once operated in a state in which cognitive functions were divided between one part of the brain that appears to be "speaking" and a second part that listens and obeys—a bicameral mind—and that the breakdown of this division gave rise to consciousness in humans. The term was coined by Jaynes, who presented the idea in his 1976 book The Origin of Consciousness in the Breakdown of the Bicameral Mind, wherein he makes the case that a bicameral mentality was the normal and ubiquitous state of the human mind as recently as 3,000 years ago, near the end of the Mediterranean bronze age.
A progress trap is the condition human societies experience when, in pursuing progress through human ingenuity, they inadvertently introduce problems that they do not have the resources or the political will to solve for fear of short-term losses in status, stability or quality of life. This prevents further progress and sometimes leads to societal collapse.
The lateralization of brain function is the tendency for some neural functions or cognitive processes to be specialized to one side of the brain or the other. The median longitudinal fissure separates the human brain into two distinct cerebral hemispheres, connected by the corpus callosum. Although the macrostructure of the two hemispheres appears to be almost identical, different composition of neuronal networks allows for specialized function that is different in each hemisphere.
Heather A. Berlin is an American neuroscientist and licensed clinical psychologist noted for her work in science communication and science outreach. Her research focuses on brain-behavior relationships affecting the prevention and treatment of impulsive and compulsive psychiatric disorders. She is also interested in the neural basis of consciousness, dynamic unconscious processes, and creativity. Berlin is host of the PBS Nova series Your Brain, the PBS series Science Goes to the Movies, the Discovery Channel series Superhuman Showdown, and StarTalk All-Stars with Neil DeGrasse Tyson.
Neuropsychoanalysis represents a synthesis of psychoanalysis and modern neuroscience. It is based on Sigmund Freud's insight that phenomena such as innate needs, perceptual consciousness and imprinting take place within a psychic apparatus to which "spatial extension and composition of several pieces" can be attributed and whose "locus ... is the brain ". Neuropsychoanalysis emerged as an interdisciplinary field of research after advances in technology made it possible to observe the bioelectrical activities of neurons in the living brain. This allowed to differentiate where, for example, the need for food begins to show neuronally, in which area of the brain the highest performance of conscious thinking of the ego are focussed, and that the department of the limbic system can permanently store the experiences partly initiated by the ego itself.
Sir James Crichton-Browne MD FRS FRSE was a leading Scottish psychiatrist, neurologist and eugenicist. He is known for studies on the relationship of mental illness to brain injury and for the development of public health policies in relation to mental health. Crichton-Browne's father was the asylum reformer Dr William A.F. Browne, a prominent member of the Edinburgh Phrenological Society and, from 1838 until 1857, the superintendent of the Crichton Royal at Dumfries where Crichton-Browne spent much of his childhood.
John Allan Hobson was an American psychiatrist and dream researcher. He was known for his research on rapid eye movement sleep. He was Professor of Psychiatry, Emeritus, Harvard Medical School, and Professor, Department of Psychiatry, Beth Israel Deaconess Medical Center.
The Edinburgh Phrenological Society was founded in 1820 by George Combe, an Edinburgh lawyer, with his physician brother Andrew Combe. The Edinburgh Society was the first and foremost phrenology grouping in Great Britain; more than forty phrenological societies followed in other parts of the British Isles. The Society's influence was greatest over its first two decades and declined in the 1840s; the final meeting was recorded in 1870.
Mark Solms is a South African psychoanalyst and neuropsychologist, who is known for his discovery of the brain mechanisms of dreaming and his use of psychoanalytic methods in contemporary neuroscience. He holds the Chair of Neuropsychology at the University of Cape Town and Groote Schuur Hospital and is the President of the South African Psychoanalytical Association. He is also Research Chair of the International Psychoanalytical Association.
Psychiatry is the medical specialty devoted to the diagnosis, prevention, and treatment of deleterious mental conditions. These include various matters related to mood, behaviour, cognition, perceptions, and emotions.
The Master and His Emissary: The Divided Brain and the Making of the Western World is a 2009 book written by psychiatrist Iain McGilchrist that deals with the specialist hemispheric functioning of the brain. The differing world views of the right and left brain have, according to the author, shaped Western culture since the time of the ancient Greek philosopher Plato, and the growing conflict between these views has implications for the way the modern world is changing. In part, McGilchrist's book, which is the product of twenty years of research, reviews the evidence of previous related research and theories, and based on this and cultural evidence, the author arrives at his own conclusions.
John Charles Cutting is a British psychiatrist specialising in schizophrenia research. He has written a number of books, and articles and reviews in professional journals, on the subjects of psychiatry, clinical psychology, schizophrenia and the functioning of the right cerebral hemisphere of the brain.
