15 Feb Perceptual Signatures

Sound Signatures 3

We will momentarily leave Yorrick in his warm, cozy waterbed, to consider perceptual signatures that take place in the world outside him. This world is characterized by patterns, visual, audio, aromatic, tactile and complex, that each have their own signature.  The section of this blog on cognition, which deals with logic and reasoning, explores that […]

13 Feb Remember Yorrick

Excavate Knowledge

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

Spiral Pattern of Light

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 or Psychic

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

Eye Storm

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 […]

11 Feb Conscious Sensibility

Spiderweb 1

Watergate Revisited More than one President of the United States has been asked this question: “What happened, and how soon did you know about it?” Many cognitive psychologists perform experiments in which they ask subjects (people) the same question, seeking to mark the boundaries between conscious and unconscious phenomena. I recently spoke of mindfulness. Wakefulness may be a […]

07 Feb Mindfulness

Attention Switch

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

Human Mind

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 […]

27 Jan Go With the Flow

Brain Flow

Modeling Neural Electrical Flow Patterns From looking at possible mechanisms for information storage, we move back to its movement. It may be important to understand the patterns of electrical flow in the brain to define good models for artificial systems that attempt to match human competence in cognitive processing tasks. This is what neural network and […]

31 Dec Signal Transduction in Neurons

Two Neurons

Wires in the Brain Electrical impulses jump from neuron to neuron in the brain through their branching nerve fibers. This movement of electrical potentials is called signal transduction, and significantly resembles the process of electrical flow in printed circuit boards and semiconductor chips. Nerve fibers (axons and dendrites) are filled with a fluid called axoplasm. […]
