The brain’s silent majority - 2009 FALL

The brain’s silent majority - 2009 FALL
When you have no clue, call it glue. “Glia,” the Greek word for glue, was the name the pathologist Rudolph Virchow gave, back in 1856, to the gelatinous substance that forms the bulk of the brain. And it stuck. These days, scientists use it to denote the matter that accounts for 90 percent of the brain’s cells and more than half its volume — but, like the late comic Rodney Dangerfield, “can’t get no respect.” “When the brain is injured, the neighborhood astrocytes go into a completely altered state.” We now know they’re doing much more. Certainly, it’s no stretch to imagine that knowing what glial cells do, and how they do it, could help explain brain disorders and how to cure them. From time to time, Ben Barres brings a brain in to his office. Barres says, “When you think about cells in the brain, pretty much the first thing you think about is neurons.” The guardian angels of the synapses Most neurobiologists are too polite to tell you that neurons, although talented, are slobs.

Culture Vaults : Resonant Frequencies and the Human Brain One of the great revelations of 20th century science is that all existence can be broken down into simple wave functions. Every photon, energy emission, and elementary particle rings with its own unique wave signature. When we see a color, we are actually seeing a distinct frequency of visible light. When we hear a sound, our eardrums are actually being vibrated by subtle waves in the air molecules around us. By studying the way that waves interact with other waves, researchers have found that even low-powered oscillations can have enormous effects on standing waves, physical structures, and even the human brain. Tesla first realized the massive potential of resonant waves in 1898 when he performed a simple experiment with an electromechanical oscillator the size of an alarm clock. In a later experiment using the same principle, Tesla clamped an oscillator to one of the exposed ground floor beams of a half built ten-story steel building. "The principle cannot fail," Tesla would say.

Quantum mind–body problem An interpretation of quantum mechanics is a set of statements which attempt to explain how quantum mechanics informs our understanding of nature. Although quantum mechanics has held up to rigorous and thorough experimental testing, many of these experiments are open to different interpretations. There exist a number of contending schools of thought, differing over whether quantum mechanics can be understood to be deterministic, which elements of quantum mechanics can be considered "real", and other matters. This question is of special interest to philosophers of physics, as physicists continue to show a strong interest in the subject. History of interpretations[edit] Main quantum mechanics interpreters Although the Copenhagen interpretation was originally most popular, quantum decoherence has gained popularity. Nature of interpretation[edit] More or less, all interpretations of quantum mechanics share two qualities: Two qualities vary among interpretations: Challenges to interpretation[edit]

The Golden Ratio in Flowers The Golden Ratio in Flowers Posted by ksakz on June 4, 2012 · 8 Comments Leonardo Fibonacci discovered an amazing sequence of numbers that ties nature and mathematics together in fascinating ways. This ratio is thought to exist in nature because its particular growth pattern is the most effective. Adolf Zeisig, a mathematician and philosopher, found the golden ratio in plant stems, veins of leaves, skeletons of animals, chemical compounds and the geometry of crystals. The Fibonacci sequence starts with 1, and each additional number is the sum of the two numbers immediately before it (1+0=1, 1+1=2, 2+1=3, 3+2=5, 5+3=8, 13, 21,34, 89, etc). Check out some more instances of the Golden Ratio in flowers below! Like this: Like Loading...

Quantum Consciousness . Stuart Hameroff Overview: Could Life And Consciousness Be Related To The Fundamental Quantum Nature Of The Universe? Consciousness defines our existence and reality. But how does the brain generate thoughts and feelings? Most explanations portray the brain as a computer, with nerve cells ("neurons") and their synaptic connections acting as simple switches, or "bits" which interact in complex ways. In this view consciousness is said to "emerge" as a novel property of complex interactions among neurons, as hurricanes and candle flames emerge from complex interactions among gas and dust molecules. We also don't know if our conscious perceptions accurately portray the external world, or if we all have similar pictures of what lies outside our conscious minds. Reality seems to be described by two sets of laws. Quantum computers differ from conventional computers which represent information as e.g. binary bits of either 1 or 0. But why are there two separate realities, and how are they related?

BRAINMETA.COM - NEUROSCIENCE, CONSCIOUSNESS, BRAIN, MIND, MIND-BRAIN, NEUROINFORMATICS, BRAIN MAPS, BRAIN ATLASES Higher consciousness Higher consciousness is the consciousness of a higher Self, transcendental reality, or God. It is "the part of the human being that is capable of transcending animal instincts". The concept developed in German Idealism, and is a central notion in contemporary popular spirituality. Philosophy[edit] Fichte[edit] Fichte distinguished the finite or empirical ego from the pure or infinite ego. Fichte (1762-1814) was one of the founding figures of German idealism, which developed from the theoretical and ethical writings of Immanuel Kant. According to Michael Whiteman, Fichte's philosophical system "is a remarkable western formulation of eastern mystical teachings (of which he seems to have had no direct knowledge)." Schopenhauer[edit] In 1812 Schopenhauer started to use the term "the better consciousness", a consciousness ... According to Schopenhauer, The better consciousness in me lifts me into a world where there is no longer personality and causality or subject or object. Religion[edit]

Quantum mind The quantum mind or quantum consciousness hypothesis proposes that classical mechanics cannot explain consciousness, while quantum mechanical phenomena, such as quantum entanglement and superposition, may play an important part in the brain's function, and could form the basis of an explanation of consciousness. It is not one theory, but a collection of distinct ideas described below. A few theoretical physicists have argued that classical physics is intrinsically incapable of explaining the holistic aspects of consciousness, whereas quantum mechanics can. The idea that quantum theory has something to do with the workings of the mind go back to Eugene Wigner, who assumed that the wave function collapses due to its interaction with consciousness. The philosopher David Chalmers has argued against quantum consciousness. Description of main quantum mind approaches[edit] David Bohm[edit] In trying to describe the nature of consciousness, Bohm discusses the experience of listening to music.

Western Philosophy Thoughts on Consciousness | OF MY OWN ACCORD So yesterday, I went to a lecture about consciousness by a neuroscientist called Murray Shanahan, from Imperial College. It was about how consciousness is constructed within the brain, how networks of neurons connect together to create hierarchies of thought and other such clever stuff. To be honest, most of it went right over my head. There was, however, an interesting thing about the way in which networks in the brain resemble social networks. This isn’t the best diagram in the world, but it hopefully helps explain how it works a bit. Its interesting to see how, whether by accident or design, we have come to create online networks that so closely resemble the processes that go on within our own brains. In the questions at the end of the lecture, one guy asked that if this system was how consciousness is created, then why is a social network such as Facebook, that relies on a very similar system, not itself a conscious entity? It got me thinking about Twitter though. Worth a go.

Extended consciousness Developed in his (1999) book, 'The Feeling of What Happens', Antonio Damasio's three layered theory of consciousness is based on a hierarchy of stages, with each stage building upon the last. The most basic representation of the organism is referred to as the Protoself, next is Core Consciousness, and finally, Extended Consciousness. Damasio, who is an internationally recognized leader in neuroscience, was educated at the University of Lisbon and currently directs the University of Southern California Brain and Creativity Institute.[1] Damasio's approach to explaining the development of consciousness relies on three notions: emotion, feeling, and feeling a feeling. Protoself[edit] Our most basic representation of self, as Damasio dubs it, is the Protoself. Multiple brain areas are required for the Protoself to function. Core consciousness[edit] Sufficiently more evolved is the second layer of Damasio’s theory, Core Consciousness. Extended consciousness[edit] References[edit]
