Brain Chemicals

In this book J. Allan Hobson offers a new understanding of altered states of consciousness based on knowledge of how our brain chemistry is balanced when we are awake and how that balance shifts when we fall asleep and dream. He draws on recent research that enables us to explain how psychedelic drugs work to disturb that balance and how similar imbalances may cause depression and schizophrenia. He also draws on work that expands our understanding of how certain drugs can correct imbalances and restore the brain's natural equilibrium.Hobson explains the chemical balance concept in terms of what we know about the regulation of normal states of consciousness over the course of the day by brain chemicals called neuromodulators. He presents striking confirmation of the principle that every drug that has transformative effects on consciousness interacts with the brain's own consciousness-altering chemicals. In the section called "The Medical Drugstore," Hobson describes drugs used to counteract anxiety and insomnia, to raise and lower mood, and to eliminate or diminish the hallucinations and delusions of schizophrenia. He discusses the risks involved in their administration, including the possibility of new disorders caused by indiscriminate long-term use. In "The Recreational Drugstore," Hobson discusses psychedelic drugs, narcotic analgesia, and natural drugs. He also considers the distinctions between legitimate and illegitimate drug use. In the concluding "Psychological Drugstore," he discusses the mind as an agent, not just the mediator, of change, and corrects many erroneous assumptions and practices that hinder the progress of psychoanalysis.

Blame It on the Brain: Distinguishing Chemical Imbalances, Brain Disorders, and Disobedience

Leukodystrophy - Leukodystrophy refers to progressive degeneration of the white matter of the brain due to imperfect growth or development of the myelin sheath, the fatty covering that acts as an insulator around nerve fiber. Myelin, which lends its color to the white matter of the brain, is a complex substance made up of at least ten different chemicals.

Russell Brain, 1st Baron Brain - Dr Walter Russell Brain, 1st Baron Brain (October 23 1895â€“December 29 1966) was a United Kingdom neurologist. He was principal author of the standard work of neurology, "Brain's Diseases of the Nervous System", and longtime editor of the neurological medical journal titled Brain.

Brain implant - The term brain implants, also known as neural implants, usually refers to devices of a technological nature that are connected directly to a biological subject's brain - usually placed on the surface of the brain, or attached to the brain's cortex. A common purpose of modern brain implants and the focus of much current research is establishing a biomedical prosthesis circumventing areas in the brain, which became dysfunctional after a stroke or other head injuries.

Ischemic cascade - The ischemic cascade is a series of biochemical reactions that take place in the brain after seconds to minutes of ischemia (inadequate blood supply) (Arnold, 2003). Most ischemic neurons that die do so due to the activation of chemicals produced during and after ischemia (Internet Stroke Center, 2003).
