16 Mar Neurons – Section 2 Intro
Neurons: Processing Elements or Storage Cells? In the Brains section of this blog, we examine the brain, its areas, and the types of neurons that populate the different layers of some of the brain’s areas. My posts in this segment will turn up the magnification and look a little deeper. What can be seen inside the cells? What is it that […]
13 Mar Intro to Understanding Context
Understanding It has been said that it is not possible to fully understand another person’s meaning without inhabiting their experiences and their current state of mind. And yet, communication is often completely successful. The most effective communications are between people who empathize well and avoid applying their own biases when listening to others. For humans, […]
10 Mar Biological Brains – Section 1 Intro
In this segment of the Understanding Context Blog, I will take a high level look at the brain: Its areas, Cell types, And functions. I’ll also explore where the brain stores and processes different types of information, including emotions. Studying the human brain is an important part of this analysis, because biological brains clearly outperform man-made information […]
26 Feb Choosing an Ontology Framework
Ontology is a knowledge representation language like Roger Schank‘s Semantic Networks and John Sowa‘s Conceptual Graphs or Doug Lenat‘s Semantic Web. An Ontology framework is the model (structure, function and content definition) in which you choose to build your ontology. Like a Relational Database or an Object Oriented Programming Language, an ontology has defined structures, functions […]
21 Jan Gating in Human Reasoning
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 […]
25 Dec Myelin Sheath Function: Insulators
Glial Cells Gray matter / white matter… what really matters? Glial cells form a white myelin sheath around axons and function as the nervous system‘s supporting actors. They are more numerous than neurons – there are over 100 billion neuroglia, many wrapped around the efferent (output) fibers of each nerve cell. They support impulse conduction by […]
24 Dec Neuron Components and Cybernetics
What About Cybernetics? The properties of subcellular neuron components, also known as organelles, are important to this research because they might contribute to the information acquisition, storage, accessing and maintenance systems of the brain. I plan to further discuss the reason for separating storage and maintenance in a post in the section on cognition. These […]
22 Dec Modeling Neural Interconnections
Neuron Branching The characteristic that distinguishes neurons from other types of cells is that they have things sticking out all over them. This phenomenon is called branching or arborization. While all cells are capable of sprouting appendages like cilia or dendrites, only some actually do. Cells that branch do so for specific reasons that are essential […]
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 […]
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 […]
