Michael Merzenich on re-wiring the brain

The Science of "Chunking," Working Memory, and How Pattern Recognition Fuels Creativity by Maria Popova “Generating interesting connections between disparate subjects is what makes art so fascinating to create and to view… We are forced to contemplate a new, higher pattern that binds lower ones together.” It seems to be the season for fascinating meditations on consciousness, exploring such questions as what happens while we sleep, how complex cognition evolved, and why the world exists. Diffusion MRI Diffusion MRI (or dMRI) is a magnetic resonance imaging (MRI) method which came into existence in the mid-1980s.[1][2][3] It allows the mapping of the diffusion process of molecules, mainly water, in biological tissues, in vivo and non-invasively. Molecular diffusion in tissues is not free, but reflects interactions with many obstacles, such as macromolecules, fibers, membranes, etc. Water molecule diffusion patterns can therefore reveal microscopic details about tissue architecture, either normal or in a diseased state. The first diffusion MRI images of the normal and diseased brain were made public in 1985.[4][5] Since then, diffusion MRI, also referred to as diffusion tensor imaging or DTI (see section below) has been extraordinarily successful.

How Great Entrepreneurs Think What distinguishes great entrepreneurs? Discussions of entrepreneurial psychology typically focus on creativity, tolerance for risk, and the desire for achievement—enviable traits that, unfortunately, are not very teachable. So Saras Sarasvathy, a professor at the University of Virginia's Darden School of Business, set out to determine how expert entrepreneurs think, with the goal of transferring that knowledge to aspiring founders.

8 Harsh Truths that Will Improve Your Life - Dumb Little Man They say life is what we make of it. By the end of this post, I hope to have helped you decide whether that statement is true or not. There is no doubt that life has its ups and downs. However, how we deal with them can sometimes make all the difference. Today I want to share eight harsh truths that I’ve come to learn from life. The Brain Needs Downs to Have Ups Four neurochemicals cause happiness : endorphins, dopamine , oxytocin and serotonin. Each evolved to do a different job. When you know what the job is, you know why your happy chemicals can't be on all the time. 1. Functional magnetic resonance imaging Researcher checking fMRI images Functional magnetic resonance imaging or functional MRI (fMRI) is a functional neuroimaging procedure using MRI technology that measures brain activity by detecting associated changes in blood flow.[1] This technique relies on the fact that cerebral blood flow and neuronal activation are coupled. When an area of the brain is in use, blood flow to that region also increases. The primary form of fMRI uses the Blood-oxygen-level dependent (BOLD) contrast,[2] discovered by Seiji Ogawa.

Thinking Methods: Creative Problem Solving They further divided the six stages into three phases, as follows: 1. Exploring the Challenge (Objective Finding, Fact Finding, and Problem Finding), Generating Ideas (Idea Finding), and Preparing for Action (Solution Finding and Acceptance Finding). Description: Since the arrival of the now classical Osborn-Parnes structure, any number of academic and business entities have re-sorted and renamed the stages and phases of what we now call the Creative Problem Solving Process (CPS). However, the originators' fundamental approach remains in tact. The Creative Problem Solving Institute of Buffalo, New York, has finessed the Osborn-Parnes process to include a divergent and a convergent stage within each of the six stages.

21 Habits of Happy People Contributed by Cindy Holbrook “Happiness is a habit – cultivate it.” ~ Elbert Hubbar Happiness is one aspiration all people share. Neuron All neurons are electrically excitable, maintaining voltage gradients across their membranes by means of metabolically driven ion pumps, which combine with ion channels embedded in the membrane to generate intracellular-versus-extracellular concentration differences of ions such as sodium, potassium, chloride, and calcium. Changes in the cross-membrane voltage can alter the function of voltage-dependent ion channels. If the voltage changes by a large enough amount, an all-or-none electrochemical pulse called an action potential is generated, which travels rapidly along the cell's axon, and activates synaptic connections with other cells when it arrives. Neurons do not undergo cell division. In most cases, neurons are generated by special types of stem cells. A type of glial cell, called astrocytes (named for being somewhat star-shaped), have also been observed to turn into neurons by virtue of the stem cell characteristic pluripotency.

Learn How to Think Different(ly) - Jeff Dyer and Hal Gregersen by Jeff Dyer and Hal Gregersen | 10:24 AM September 27, 2011 In the Economist review of our book, The Innovator’s DNA, the reviewer wondered whether genius-level innovators such as Marc Benioff, Jeff Bezos, and Steve Jobs challenge the idea that working adults can really learn how to think differently and become innovators. We don’t think so. Remember, it was Steve Jobs who jump-started the now-famous “Think Different” advertising campaign as a way to inspire consumers and recharge Apple’s innovation efforts.

Twelve Virtues of Rationality by Eliezer Yudkowsky - StumbleUpon by Eliezer Yudkowsky The first virtue is curiosity. A burning itch to know is higher than a solemn vow to pursue truth. To feel the burning itch of curiosity requires both that you be ignorant, and that you desire to relinquish your ignorance. If in your heart you believe you already know, or if in your heart you do not wish to know, then your questioning will be purposeless and your skills without direction. Curiosity seeks to annihilate itself; there is no curiosity that does not want an answer.

Brain Atlas - Introduction The central nervous system (CNS) consists of the brain and the spinal cord, immersed in the cerebrospinal fluid (CSF). Weighing about 3 pounds (1.4 kilograms), the brain consists of three main structures: the cerebrum, the cerebellum and the brainstem. Cerebrum - divided into two hemispheres (left and right), each consists of four lobes (frontal, parietal, occipital and temporal).

Realistic Lateral Thinking Puzzles Lateral Thinking Puzzles, unlike most puzzles, are inexact. In a sense, they are a hybrid between puzzles and storytelling. In each puzzle, some clues to a scenario are given, but the clues don't tell the full story. Your job is to fill in the details and complete the story. Obviously, there is usually more than one answer to any given puzzle, but, in general, only one solution is truly satisfying. You can try solving these puzzles on your own -- that's certainly a legitimate way to go about this -- but usually you can have more fun if you involve other people.

Michael Merzenich talks about the brain's ability to change itself. Many neurologists distinguishe two phases: the 'critical period' and refinement. In the critical period the brain sets up its processing so that it can act selectively on sounds, images, and other signals in its environment. During the refinement period, which lasts a lifetime, the brain uses behaviour control (reinforment learing) to lean skills. The brain makes representations of temporally correlated events (sensatations) that affect its body; it does this via physical change. by kaspervandenberg Dec 27
