10 Jan Shades of Meaning
I have been sharing my observations on the electrical behavior of the brain this month, with a brief glance at perspectives on perception. My work began, and may end with language. As my springboard into artificial intelligence, I’ve been trying for years to develop computer programs that can understand your intent and use that understanding […]
09 Jan What of Perception
Questions Cognitive Modelers Might Ask The biological and chemical processes associated with brain activity are the foundation on which our exploration of the cognitive mind is built. Yet the physiological underpinnings are not sufficient, in themselves, to lead us to the next cybernetic level. Too many questions are left unanswered. In this section of Understanding […]
30 Dec Aristotle and von Neumann
In the 1950’s, John von Neumann compared the computer to the brain. Scientific inquiry that laid the foundation for that comparison, however, had begun long before. The influence of the Greek philosopher Aristotle’s association theory (metaphysics), for example, is evident in neural net theory. In The Computer and the Brain, Dr. von Neumann describes how […]
30 Dec Context Models
Building a Model The goals of the research that evolved into Understanding Context were twofold: to investigate human physiology/psychology for clues that would let us evaluate neuromorphic computational paradigms; and to explore the possibility of new computational models using context to correlate and associate concepts. Birds fly and they are lightweight. Building models of flight with lightweight materials works […]
25 Oct Chaos and Order, Fractals and Language Power
Fractals may appear chaotic when viewed from a distance, but they exhibit recognizable patterns or mirrored structures when viewed up close. So, too, there is a distance we humans must travel from the chaotic structure of a thought to the regular structure of a meaningful dialog made of symbols in the form of audible words and body language. […]
25 Aug Learning from Brain Disorders
Serotonin Imbalance I am possessed of an orderly disorder. My “Obsessive-Compulsive Disorder” (OCD) compels me to make sure everything is lined up nicely. Do good managers benefit from a little OCD? Today’s post is about what we can learn about the brain from observing what happens when something isn’t exactly right. Collette Bouchez, on WebMD, tells us […]
10 Jul Mainspring of Language Learning
The brain wants something to happen so it can learn. Almost anything that is not nothing will stimulate neuron growth. There’s a good Radio Lab show that explores research on this topic at “How Does Your Brain Grow.” The program includes reference to “studies in which thinking alone—brain puzzles and learning new languages—can actually stave off the onset of […]
19 Mar Neural Networks – Section 3 Intro
It’s all in your head My posts on Brains and Neurons show us there is a sense of structure and order in the brain. By looking at the brain’s areas, we see how each plays a special role in processing the information necessary to support human cognition and other activities. We’ve looked at neurons and learned that each type has its own components, […]
17 Mar Intro to Cybernetic Models
Are you my Motherboard? From Eliza to Watson, Jeeves, Siri and Alfred, people have been naming their computers. Some systems are named after their inventors – like Wolfram Alpha and its siblings. Who is JARVIS? Just Another Rather Very Intelligent System? These attempts have, in their own little ways, touched our lives. But we are still waiting on the cusp of an innovation that will […]
27 Dec Microtubules
Microtubules Neurons have hundreds of MT distributed in the soma and in the axon and dendrites. Microtubules, like IF, are filamentous organelles that form the cytoskeleton of neurons. Their cylindrical, composite polymers comprise part of the cytoskeletal infrastructure of cells. Their cylinders are long, and they possess a distinct polarity. Their surfaces are composed of spherical tubulin in columns […]
