07 Feb Your Place in the Noosphere

René Descartes suggested that if you think, you exist: cogito ergo sum. To think, to know, to intuit, to be or not to be… these are questions that lead us to consider the noosphere. Taxonomies attempt to categorize things in the universe by placing them in buckets in which all the things in the same […]

21 Jan Gating in Human Reasoning

Filter

Both neuroscience and computer science have borrowed the metaphor of the gate for representing the function of letting some things go through and restricting others. In computing it is mostly a binary function: if the gate is closed, nothing comes in, if the gate is open, everything that is at the threshold comes in. I chose the pictures above because gates […]

19 Jan Theories on Microtubules’ Function in Thought

Microtubules in the Cytoskeleton

Microtubule Functions Continuing to look inside neurons for the knowledge storage and processing mechanisms, let’s consider what Microtubules do. Microtubules serve many clearly identified functions. These functions include acting as structural members of the cytoskeleton, providing cellular orientation, and guiding membrane and cytoplasmic movements. In addition to these known functions, there is evidence that suggests […]

27 Dec Microtubules

Microtubule Isozymes

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 […]

27 Dec Cytoskeleton Components in Cognition

Cytoskeleton

A Neuron’s Skeleton Unlike the external structure of many spheroid and amorphous cells, the external structure of neurons is complex and rigidly determined. As you may remember from earlier posts, the many different types of neurons residing in particular cortical strata (in layers of the gray and white matter) each have distinctive characteristics that enable […]

03 Dec Language Expressiveness

Expressiveness Human languages are eloquent vehicles for giving form to the motion of the human mind. They provide symbol-rich expressions for our thoughts and communications. Language is dynamic and defies circumscription. Yet, it is circumspect; it is also useful and extremely beautiful. To comprehend is to begin to capture that beauty. The expressiveness of language […]

12 Nov Context Powers Backward Chaining Logic

Forward Chaining Rules

A popular success strategies book suggests that if we “Begin with the End in Mind” we are likely to get where we’re going more consistently. We wander less if we think about what we want at the end from the very first steps of our journeys. Context helps us do that. Human behaviorists and philosophers have […]

10 Nov Seeking a Universal Theory of Knowledge

Top Level Ontology

As a fundamental premise for this post, this blog as a whole, and my life’s work, I propose that language and “real world knowledge” are inextricably connected, and neither functions well without the other. This is why, in my opinion, natural language processing (NLP) initiatives focusing exclusively, or even primarily on language structure have significant […]

05 Nov Evolution of Language

Dimensions

Evolution of Language Did humans become smart by necessity? With the forces of nature combined to rig the test for “survival of the fittest”, as human evolution from lower forms, how did these ill-equipped creatures, with their weak jaws and thin hides, make the natural-selection cut? It sounds like it was a perilous journey. One […]

19 Oct Think Before You Speak?

Brain Mouth

How closely is your brain connected to your mouth? Please don’t answer that. I want to blog about it for awhile so hold the thought. There is a bunch of electrical activity in the brain around organizing concepts into context, and a bunch more around putting your thoughts into words. This organizing and putting may […]
