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 […]
27 Dec Cytoskeleton Components in Cognition
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 […]
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 […]
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 […]
20 Jun Allusion of Clarity
Speaking to an associate at work I told him that a certain tool allows us to perform a complex technical change “with impunity”. My intent was to point out that without the tool, the change would create major ripple effects, breaking large amounts of code that would need to be fixed. He said that he would restate […]
13 Jun The Mind and its Brain
Mind-Brain Dualism While brains can be weighed, minds are weightless. Despite some differences of opinion about what all to put on the scale, we can get usable numbers about brain weight and changes in brain weight due to certain phenomena such as changes in age. Of course, the mind and brain may be one and the same – there […]
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 […]
