Brainwave entrainment. Brainwave Entrainment is any practice that aims to cause brainwave frequencies to fall into step with a periodic stimulus having a frequency corresponding to the intended brain-state (for example, to induce sleep), usually attempted with the use of specialized software. It purportedly depends upon a "frequency following" response on the assumption that the human brain has a tendency to change its dominant EEG frequency towards the frequency of a dominant external stimulus. [citation needed] Such a stimulus is often aural, as in the case of binaural or monaural beats and isochronic tones, or else visual, as with a dreamachine, a combination of the two with a mind machine, or even electromagnetic radiation. Hemispheric Synchronization, a potential and generally desired result of brainwave entrainment, refers to a state when the brainwave pattern of the right and left hemispheres become alike.
A person with similar activity in both hemispheres is alleged[by whom?] History[edit] Notes[edit] Jim Robbins. Mind in Life - Evan Thompson. FRANCISCO J. VARELA: 1946-2001. THE EMERGENT SELF. "Why do emergent selves, virtual identities, pop up all over the place, creating worlds, whether at the mind/body level, the cellular level, or the transorganism level? This phenomenon is something so productive that it doesn't cease creating entirely new realms: life, mind, and societies. Yet these emergent selves are based on processes so shifty, so ungrounded, that we have an apparent paradox between the solidity of what appears to show up and its groundlessness. That, to me, is the key and eternal question. " FRANCISCO VARELA The Emergent Self [6.5.01] Francisco Varela died on May 28 at his home in Paris. According to his friend and collaborator Evan Thompson "I am told he died completely calm and at peace.
I spent several days last week with him and his family. Francisco, an experimental and theoretical biologist, studied what he termed "emergent selves" or "virtual identities. " In 1995 I talked to Francisco for my book The Third Culture (Simon & Schuster, 1995.

Francisco Varela « Neurophenomenology. (Part I is here, and part III is here) In certain respects, development of the view that embodied experience is crucial to understanding the mind and brain reached a nadir in the period after World War II, at least within psychology. Behaviorism had redefined psychology as an “objective” science with no need to refer to consciousness or phenomenology.
There was continuation of phenomenological research from the German gestalt psychologists, but it was not until after World War II that clinically-oriented humanistic psychology explicitly articulated the need for more holistic, “person-centric” perspectives emphasizing existential concerns: the search for meaning, the experience of health and illness, emotions, and consciousness. However, clinical neurologists continued to advance an approach to psychological and cognitive phenomena that reflected a richer and broader understanding of the mind.

Current researches and collaborations include: Neuro-functional (fMRI) and neuro-dynamical (EEG) study of several standard meditative states (concentration/mindfulness, compassion and loving-kindness, and open presence meditations) in a group of highly trained Buddhist practitioners (more than 10, 000 hours of meditation in life).

The brain's center of reasoning and problem solving is among the last to mature, a new study graphically reveals. The decade-long magnetic resonance imaging (MRI) study of normal brain development, from ages 4 to 21, by researchers at NIH's National Institute of Mental Health (NIMH) and University of California Los Angeles (UCLA) shows that such "higher-order" brain centers, such as the prefrontal cortex, don't fully develop until young adulthood. A time-lapse 3-D movie that compresses 15 years of human brain maturation, ages 5 to 20, into seconds shows gray matter - the working tissue of the brain's cortex - diminishing in a back-to-front wave, likely reflecting the pruning of unused neuronal connections during the teen years.
Cortex areas can be seen maturing at ages in which relevant cognitive and functional developmental milestones occur. The sequence of maturation also roughly parallels the evolution of the mammalian brain, suggest Drs. . [1] Nitin Gogtay MD, Jay N. Morality Study Narrows Gap Between Mind And Brain. Our brains are wired so we can better hear ourselves speak, new study shows. Like the mute button on the TV remote control, our brains filter out unwanted noise so we can focus on what we’re listening to.
But when it comes to following our own speech, a new brain study from the University of California, Berkeley, shows that instead of one homogenous mute button, we have a network of volume settings that can selectively silence and amplify the sounds we make and hear. Activity in the auditory cortex when we speak and listen is amplified in some regions of the brain and muted in others. In this image, the black line represents muting activity when we speak. (Courtesy of Adeen Flinker) Neuroscientists from UC Berkeley, UCSF and Johns Hopkins University tracked the electrical signals emitted from the brains of hospitalized epilepsy patients.
They discovered that neurons in one part of the patients’ hearing mechanism were dimmed when they talked, while neurons in other parts lit up. The auditory cortex is a region of the brain’s temporal lobe that deals with sound. Brain+Illusions.jpg (JPEG Image, 950x848 pixels) - Scaled (71. Clearing the Mind: How the Brain Cuts the Clutter | Mind, Brain & Senses. Newly discovered neurons in the front of the brain act as the bouncers at the doors of the senses, letting in only the most important of the trillions of signals our bodies receive. Problems with these neurons could be the source of some symptoms of diseases like attention deficit disorder and schizophrenia. "The brain doesn't have enough capacity to process all the information that is coming into your senses," said study researcher Julio Martinez-Trujillo, of McGill University in Montreal. "We found that there are some cells, some neurons in the prefrontal cortex, which have the ability to suppress the information that you aren't interested in.
They are like filters. " Humans are constantly taking in huge streams of data from each of our senses. A cluttered mind This "brain clutter," or inability to filter out unnecessary information, is a possible mechanism of diseases like attention deficit hyperactivity disorder (ADHD) and schizophrenia. Mindful monkeys. Reconstructing visual experiences from brain activity evoked by natural movies. - GallantLabUCB. Whole Brain Emulation: The Logical Endpoint of Neuroinformatics? The riddle of free will goes unsolved. Graham Lawton, deputy magazine editor Neuroscientist Michael Gazzaniga's Who's In Charge?
Free will and the science of the brain is fascinating, but doesn't deliver on its promise ABOUT half way through this fascinating book, Michael Gazzaniga harks back to his previous one, Human. He wanted to call it Phase Shift, he says, but his publisher overruled him. Gazzaniga - one of the giants of modern neuroscience - tells this story to illustrate a point about the difference between animal and human brains, but by the end of the book it has taken on a different complexion. The book is based on Gazzaniga's contribution to the Gifford lecture series, established in 1887 at four prestigious British universities to "promote and diffuse the study of Natural Theology in the widest sense of the term".
As I read this horrific tale, I was expecting it to be the point where Gazzaniga finally takes on the problem of free will. So what of free will? Gazzaniga's solution is also a familiar one. The Brain is Wider Than the Sky by Bryan Appleyard – review | Books | The Observer. MRI images are modern equivalent of Galileo's drawings of the moon. Photograph: Rex Features In 1610 Italian astronomer Galileo Galilei published Starry Messenger, a book of telescopic observations of the night sky, and opened the heavens to busy and ambitious imaginations. Johannes Kepler imagined a manned voyage to the moon in The Dream (1634). Galileo gave us much to look forward to. But the world never turns out to be what we expected.
