15 Sep What is Inside Neurons?
Intracellular Structure of Neurons In earlier posts, we examined the brain, its areas, and the types of neurons that populate the different layers of some of the brain’s areas. In this post and more to follow, we will turn up the magnification and look a little deeper. What can be seen inside the cells? What […]
07 Sep Quest for the Knowledge Enterprise
Do you need a Private Eye? As an Intelligence Professional, my mission was to seek out information that others were trying to conceal. Do you ever feel like that is too often your task when trying to find the answers to life’s persistent questions, or even something you need to buy? In an enterprise, those answers […]
06 Sep Varieties of Neural Circuits in the Cerebellum
The Cerebellum In this post we explore the roles and varieties of neural circuits of the cerebellum in motor control and the maintenance of life-support systems. The layers of the cerebellum have different cell populations, and the types of cells have radically different forms. Three main points will be made today: the morphology of cells and layers […]
05 Sep Brain Form and Function
Functional Morphology I’ve addressed questions related to modeling form, function and process in an earlier post. Today’s post drills down in some specific areas to point out some important connections between form and function that could contribute to engineering systems that more accurately model the human brain. Paul Churchland suggests that many AI initiatives have […]
31 Aug Building a Cathedral of Knowledge
Good fiction, especially good historical fiction, gets my brain spinning. Ken Follett‘s The Pillars of the Earth and World Without End describe the technology, born in the “Dark Ages” in which mortal men were able, with limited technologies, to build edifices that could stand throughout the ages. At the same time as Mr. Follett’s mythical cathedral […]
30 Aug Eclecticism and Cognitive Modeling
Cognitive Science Hybrids in plants and automobiles are great. Perhaps in computers and apps as well. I have always thought of myself as deeply interested in the “cross-pollination of ideas.” This includes, when appropriate, snipping sequences and splicing to create genetically modified innovations. The posts in the Understanding Context blog span the knowledge and theories […]
29 Aug Layers of Brain Complexity
Hierarchy: A Structural Aspect of Thought The complexity of the cerebrum is necessitated by its function as the center of cognition. Before looking at cerebral structure, consider some of the functions of thought. Thinking involves accessing memory to find what perceived data is stored, what other data in memory it is associated with, and what is the […]
29 Aug Black Boxes: Specialized Areas of the Brain
The Black Box Black Box is a term used to describe a mechanical device that does something inside, but whose functions are not visible from the outside. Specialized areas of the brain may operate as black boxes. Activation flows in and activation flows out, and what happens inside may have no direct affect on other […]
28 Aug Sensory Input to the Brain
Part of the definition of any computer program is defining the inputs and outputs, where they come from, what they are and where they get processed. Fortunately, we know enough about the brain to answer many of these questions, thus we have a basis for defining artificial models that, in some way, mimic these elements of […]
27 Aug Brain Correlation Processes
Many computer systems focus on a single capability, one task or just one dimension of a complex process. Sentient brain activity is an example of a complex process with many dimensions. Optical character recognition, such as identifying a capital “Q” on a piece of paper, is an example of a problem with three dimensions: Length, […]
