13 Feb Remember Yorrick
Mouldering Memories Sometimes dredging up old memories is a major operation in excavation. Yet we have an amazing capacity to retain information learned long ago and not recalled in recent memory. Today, I’d like to address questions of learning, especially in the context of the earliest learned things. In order to recognize something, we must […]
13 Feb Yorrick: Seeds of Knowledge
A Wise Geek once said: “Knowledge acquisition typically refers to the process of acquiring, processing, understanding, and recalling information through one of a number of methods. This is often a field of study closely tied to cognition, memory, and the way in which human beings are able to understand the world around them.” Our exploration begins […]
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 […]
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 […]
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 […]
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 […]
25 Jan The Chromophore as Digital Bit
I have opined in prior posts that the skeletal components that give structure to axons and dendrites, especially microtubules, may play a larger role in cognition than previously thought. The illustration of microtubule structure at right shows how the alpha and beta tubulin dimers string themselves together to make protofilaments, which further join one another […]
18 Jan Multi-Layered Perceptron
Multi-Layered Perceptron In prior posts we introduced the concept of the artificial neural network and the perceptron model as a simple implementation of a neural network. We showed the structure, including an input layer and an output layer. Let’s look at one of the typical approaches for processing input to derive the output. The net output of […]
13 Jan Harmonic Convergence of Light
Light waves diverge and converge and bend on their journey to places where they are perceived. We choose to focus, perceived light waves enter us through the portals of our eyes, then flow through the visual cortex and resonate in the brain until they trigger recognition, often very quickly. The illustration shows a lens that […]
