Some Brain Connections are Not Complete until Your 20s

Myelination Do you know that some brain connections are not complete until your 20s? The process is called myelination. It is the coating of neurons with a chemical insulator which makes a signal travel along it up to 100 times faster. There is signal regeneration at the nodes of Ranvier. The effect is similar to…

Learning by Ignoring Details

Input enters black box. output exits

Lately I have been trying to see if I can program the Propeller microcontroller chip to act like a neuron. Using the Hydra kit—propeller chip, SPIN programming language, and peripheral drivers pre-coded for a game machine—I’m overwhelmed by the eight hundred page guide, the intricate links between the components, and the electrical know-how presumed but…

Pattern-Matching and Invariance

Seawall with waves crashing against it

In neuroscience, the process I call pattern-matching is often called invariance. Yohan John in Quora raises the question and suggests the form of the answer: How does your brain discover similarity in the midst of so much dissimilarity?

Yet, when it continued worsen and I could no longer draw boxes, label them, and connect them with arrows, I lost a lot of brainstorming ability. I had…

Complicated Thought

One function, many inputs

It surprised me to realize that there is a second way in which thoughts can be complicated. Complicated thoughts being those that require intense concentration to understand. Many Inputs to Function The typical way that I label thoughts as complicated occurs when there are many variables to consider simultaneously for an important problem to be…
