Here&#8217;s the scoop&#8230;<\/p>\n<h2>Step 1: Neuroplasticity<\/h2>\n<p>For much of the 20th century, neuroscientists believed that brains developed during early childhood. However, relatively quickly, they arrived at their final, unchanging form.<\/p>\n<p>With newer technologies, however, we now know that brains keep changing throughout our lives. We&#8217;ve even got a word for a brain&#8217;s ability to change: &#8220;neuroplasticity.&#8221; (&#8220;neuro&#8221; = brain; &#8220;plastic&#8221; = change.)<\/p>\n<p>Because this finding contradicts so many decades of neuroscientific belief, researchers have been REALLY excited about it. When you hear them at a talk, you can see their eyes grow wide with wonder.<\/p>\n<p>Brains change throughout our lives.<\/p>\n<h2>Step 2: Myelin<\/h2>\n<p>Like babies, neurons are born naked.<\/p>\n<p>Of course, neurons carry electrical signals, and exposed wires don&#8217;t do that very effectively. Over time, therefore, your brain needs to insulate those naked neurons.<\/p>\n<p>It does so with &#8220;myelin sheathing&#8221;; a phrase that neuroscientists use so they don&#8217;t have to say &#8220;little white hot-dog buns made of fat.&#8221; But: that&#8217;s what myelin sheathing is &#8212; fat.<\/p>\n<p>Myelination benefits all sorts of human activities. <a href=\"https:\/\/braindevs.net\/blog\/\/wp-content\/uploads\/2018\/02\/AdobeStock_105291054_Credit.jpg\"><img decoding=\"async\" class=\"size-medium wp-image-3003 alignright\" src=\"https:\/\/braindevs.net\/blog\/\/wp-content\/uploads\/2018\/02\/AdobeStock_105291054_Credit-300x169.jpg\" alt=\"neuroplasticity and myelin\" width=\"300\" height=\"169\" srcset=\"https:\/\/www.learningandthebrain.com\/blog\/wp-content\/uploads\/2018\/02\/AdobeStock_105291054_Credit-300x169.jpg 300w, https:\/\/www.learningandthebrain.com\/blog\/wp-content\/uploads\/2018\/02\/AdobeStock_105291054_Credit-768x432.jpg 768w, https:\/\/www.learningandthebrain.com\/blog\/wp-content\/uploads\/2018\/02\/AdobeStock_105291054_Credit-1024x576.jpg 1024w\" sizes=\"(max-width: 300px) 100vw, 300px\" \/><\/a>When neurons myelinate, they carry their signals up to 100 times faster, and so perform the same job considerably more efficiently.<\/p>\n<p>For example: babies learn to walk when the motor neurons responsible for that part of the body myelinate. (If you&#8217;re particularly interesting in myelination, check out <a href=\"https:\/\/braindevs.net\/blog\/\/practice-makes-myelin\/\" target=\"_blank\" rel=\"noopener\">this video<\/a>.)<\/p>\n<p>How does the brain myelinate those neurons? Highly specialized brain cells &#8212; with the poetic name &#8220;oligodendrocytes&#8221; &#8212; work like tiny bricklayers to create this essential coating.<\/p>\n<h2>Step 3: Neuroplasticity and Myelin<\/h2>\n<p>In a recent <a href=\"http:\/\/jonlieffmd.com\/blog\/myelin-facilitation-of-whole-brain-neuroplasticity\" target=\"_blank\" rel=\"noopener\">article<\/a> over at Searching for the Mind, Dr. Jon Lieff explores the complexities of these essential processes. In particular, as he describes it, he sees myelination as essential for &#8220;whole brain neuroplasticity.&#8221;<\/p>\n<p>It&#8217;s an article for those of you who really want to know more about highly complex brain mechanics.
