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 […]
02 Jan Synapse Formation
Many neurons have only a few synapses. Others, like giant pyramidal and Purkinje cells, may have tens or even hundreds of thousands of synapses. At the conclusion of the complex growth process, called synaptogenesis, in which growth cones at the tips of spines, axons, and dendrites propel or draw the fiber through the crowded gray and white matter […]
06 Mar Correlation in Neuroeconomics
I find that driving when my body is tense, especially on slick roads or in poor visibility, is uncomfortable to the point of danger. Stress is a killer. I found, as a student, that relaxing at the piano just before going in to the test helped me perform better (on the test). I think many […]
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 […]
17 Aug Stimuli
Responses to Stimuli When we speak of computational systems, we use words like “input” and “output” and “program“. When computers become able to communicate, understand and process knowledge in context, will we use different words: words that are more anthropomorphic? I’ve been playing with anthropomorphic concepts with MIPUS. In today’s post I will draw us […]
11 Aug Emotion – The Perturbable Mr. Amygdala
Fear and the Amygdala Have you ever been asked not to be so emotional, or on the contrary, to show more emotion? Or have you been asked to suppress a specific emotion, such as fear? I recall a scene from an Indiana Jones movie in which, after a scene of amazing heroics, a pilot tells […]
03 Aug Exformation vs. Subtext
Many of us humans like to congregate and communicate. Much of our communication, including this blog, is intended to be shared widely and to persist beyond the moment, whether we are attempting to share the thought of the moment, or change the course of human history. When we congregate, whether for a TED talk, a […]
19 Jun Did You Change Your Mind?
Change is a Constant There is a beautiful song from the by the Rascals that asks: “In a world that’s constantly changing, how can I be sure?” When confronted with the dirty little uncertainties that swirl around everyday life and interpersonal relations, anyone’s mind may experience turmoil. How do we resolve it? What mental processes keep us from […]
15 Jun Natural Intelligence
The Gross Anatomy of Smart The biology of understanding is not fully understood. But there are some things we can infer from what we know about how the brain works that may help us in modeling smarter systems. I love looking inside the brain for clues on what it does so I can help design […]
12 Jun To Choose or not to Choose
Leg-room, anyone? The CEO of a major Airline recently stated that a-la-carte pricing of flight upgrades (such as extra baggage, preferred seating and food) is better because Americans demand “choice“. I remember my knee-jerk reaction: “Yeah – and they are choosing discount airlines that don’t charge for what was once part of the bargain.” It […]
