12 Feb Conscious Phenomena
Conscious Phenomena For the past few posts, I have been exploring consciousness. Extra-sensory perception is a part, or an extension of consciousness. Are you sometimes psychic? Some people have truly remarkable extra-sensory capabilities while others do not. I read a short story by Ursula K. Le Guin, though I can’t for the life of me remember the […]
11 Feb Introspection as Empirical Science
Heightened awareness – inner vision – focus. I have looked to psychology, neuroscience and philosophy for clues about how to get computers to pay attention to all the right cues so they can engage in meaningful dialog with me. Much of what I encounter in the literature mixes experimental results with empirical observations. And many paths lead […]
11 Feb Conscious Sensibility
Watergate Revisited More than one President of the United States has been asked this question: “What happened, and how soon did you know about it?” Many cognitive psychologists perform experiments in which they ask subjects (people) the same question, seeking to mark the boundaries between conscious and unconscious phenomena. I recently spoke of mindfulness. Wakefulness may be a […]
08 Feb Seeing Within: Proprioception for Robots
I saw a couple movies awhile back, “The Terminator” and “Terminator 2” in which artificial intelligence in computers became hazardous to the survival of humanity. One of the premises, as I recall, was that the critical event that lead to the disastrous attempt of man-made machines to destroy humanity, was when they became “self-aware”. This […]
07 Feb Mindfulness
Imagine being able to flip a switch and get quantitative and qualitative improvements to your intelligence. Mindfulness, in the form of directing your attention or focus can induce changes in the structure and function of the brain. When I was in school, I learned that taking notes helped me not only focus better on what I […]
05 Feb Rings of Power: Workflow and Business Rules
Gandalf the Wizard explained the writing on the “One Ring”: “One Ring to rule them all, One Ring to find them, One Ring to bring them all and in the darkness bind them“ Such a ring would be a nice thing to have, as long as it didn’t make you into a fascist – the […]
03 Feb Mapping a Thought
What is truly going on in a network of billions of cells with trillions of connections? Can we even begin to figure it out – is mapping a thought possible? When I was in the midst of my studies in which I initially wrote this, MRIs and CAT scans were the best of our ability […]
31 Jan Feature Selectivity in Vision
This post is another in the series on specialization, in which the author stresses the need for very heterogeneous models for imitating brain capabilities with computers. An important discovery of neurophysiological and cybernetic research is that many neurons, particularly those in areas of the brain that specialize in processing perceptual data, are feature selective. Vision processing is […]
30 Jan From Aristotle to the Enchanted Loom
“Swiftly the brain becomes an enchanted loom, where millions of flashing shuttles weave a dissolving pattern-always a meaningful pattern-though never an abiding one” (Charles Sherrington). What of the centillion warps and woofs of ideation? Does it never abide? Passing seems to take away all that was ever weft, unless the Gods endow immortality on our thoughts and carry them […]
27 Jan Go With the Flow
Modeling Neural Electrical Flow Patterns From looking at possible mechanisms for information storage, we move back to its movement. It may be important to understand the patterns of electrical flow in the brain to define good models for artificial systems that attempt to match human competence in cognitive processing tasks. This is what neural network and […]
