SIDELIGHTS: A writer, educator, and neurobiologist, Walter J. Freeman is a noted authority on brain function and related areas of neurobiology. As a researcher at the University of California, Berkeley, Freeman studies complex biological and bioelectrical brain activity. His findings suggest several intriguing ways to look at brain function. Freeman believes that there is a constant background noise in the brain, a chaotic state of electrical activity that "generates a flexible 'I don't know' energy state, from which massive numbers of neurons can be prodded instantaneously to work together and respond to new as well as previously encountered sensory stimuli without getting hopelessly confused," remarked Bruce Bower in Science News. This suggests that the brain has available to itself at all times all previously gathered knowledge about the world, which can be instantaneously accessed and processed when an organism encounters a stimulus. Prior knowledge thus does not need to be retrieved from any storage place in the brain. From this charged and ready "I don't know" state, "massive numbers of neurons can instantly generate coordinated responses to sensations," Bower noted. (Neurons are nerve cells in the brain.) Freeman has also found that individual brains are in all ways isolated from other brains; they do not cooperate with any part of the neurological system of other organisms. At first, this finding suggests that there should be great difficulty in forming the types of mutual trust and cooperation among organisms that result in communities, functioning societies, and even successful reproduction and raising of offspring. However, Freeman indicates that "Fortunately, evolution equipped mammals with a biological mechanism for bridging the gap between isolated brains so that pairs of animals in a species can reproduce and raise their offspring," Bower stated.
In How Brains Make up Their Minds, Freeman discusses in depth the function of the brain and how it works to satisfy the needs and desires of individual humans. He describes the nature of neurons and how they function. He outlines how structures in the brain change and adapt as humans learn, experience the environment, and interact socially. These changes shape each individual's beliefs and how each person reacts to the world. Freeman also lists the functions of the brain that are absolutely critical to life, including the brain's role in stimulating mitochondria (specialized membrane structures) to activities that prolong life. Though the book does not suffer from a lack of facts, it also contains Freeman's detailed description of his own ideas in theoretical neurobiology. "The talented author writes in a clear and persuasive fashion and his book is organized so as to answer the reader's questions," commented Stewart Wolf in a review for Integrative Physiological and Behavioral Science.
Freeman told CA: "My favorite book is Societies of Brains: A Study in the Neuroscience of Love and Hate, because I wrote it for the sheer pleasure of doing so."

Encyclopedia.com gives you the ability to cite reference entries and articles according to common styles from the Modern Language Association (MLA), The Chicago Manual of Style, and the American Psychological Association (APA).
Within the “Cite this article” tool, pick a style to see how all available information looks when formatted according to that style. Then, copy and paste the text into your bibliography or works cited list.
Because each style has its own formatting nuances that evolve over time and not all information is available for every reference entry or article, Encyclopedia.com cannot guarantee each citation it generates. Therefore, it’s best to use Encyclopedia.com citations as a starting point before checking the style against your school or publication’s requirements and the most-recent information available at these sites:
Modern Language Association
The Chicago Manual of Style
American Psychological Association
- Most online reference entries and articles do not have page numbers. Therefore, that information is unavailable for most Encyclopedia.com content. However, the date of retrieval is often important. Refer to each style’s convention regarding the best way to format page numbers and retrieval dates.
- In addition to the MLA, Chicago, and APA styles, your school, university, publication, or institution may have its own requirements for citations. Therefore, be sure to refer to those guidelines when editing your bibliography or works cited list.
