The Human Brain, Part 1 of a Series

Before getting into information about the brain, so it’s not necessary to spend a lot of time in a medical dictionary, we need to define some words and brain growth patterns. 

Neurons, cells that communicate events in and outside the body.  Axons, cell fibers of a neuron that carry information away.  Dendrites, receptors on neurons. Synapse, chemical bridges from one neuron to another. Reptilian brain, the first part of the total human brain to develop from conception and evolution.  The limbic brain is the second to develop as we grow.  The neo-cortex is the third portion of the brain to develop both in growth and during evolution.  Humans are the only species to have this section of the total brain. The frontal lobe is the area of the neo-cortex associated with synthesis of ideas, compassion and altruism.  The parietal lobe is area of the neo-cortex connected to synthesis of information and storage of all items of sensory perception (touch, smell, etc.)  The temporal lobe of the neo-cortex area is connected with auditory and olfactory function.  The occipital lobe is connected with visual functions.  The motor cortex where all motor functions begin.  Sensory cortex, where all sensory functions are received and deciphered.  Myelin is a fatty insulation around neurons and axons.  The cerebellum is the balance and coordination area of the brain. The right (gestalt) brain hemisphere is associated with creativity, movement, intuition, and subjective reasoning.  The left (logic) brain hemisphere is connected with organization, language, linear function and objective reasoning.  The corpus callosum is a bundle of nerve fibers that connect the right and left hemispheres.  The sympathetic nervous system is associated with body stress, survival and fight or flight.  The parasympathetic system is associated with relaxed body functioning.

Brain growth and learning occur in spurts, separated by plateaus.  There are always variables, but most fall within these parameters.  On an oscilloscope, brain growth rhythms appear like long ocean swells with peaks and troughs.  Hang on to this and you’ll see how it matches with the evolutionary brain development phases.

Between pre-natal and 15 months there’s a growth spurt in the sensorimotor area involving crawling, walking and finding out how the body works, and is  followed by a plateau to 2 years.  From 2 to 4 years a growth spurt occurs in what’s termed the pre-operational area, getting it all together and figuring out how to best breakdown your parents willpower and assault the next phase of life, this is where the phrase “terrible two’s” originates.  From 4 to 6 years there’s a plateau and a mellower period of reflection on what didn’t work.  From 6 to 8 years a growth spurt occurs in the “concrete” operational area.  From 8 to 10, we’re back in “a figure out what went wrong and why it didn’t work plateau.”  From 10 to 12 we enter another spurt called the “formal operational” period.  Uh-oh, puberty ahead.  From 12 to 14 years we plateau secure in the timeframe that we know all, see all and that the world revolves around us.  From 14 to 16, if we’ve developed beyond 14, we enter a problem finding growth spurt.  We find out we have problems, that maybe we don’t know all and we try to find out what the problems are.  Again, this only happens if we’ve made it past the terrible two’s and the “know all 14’s”.  From 16 to 22 we plateau during which time we do extreme sports, video games and no-brainer activities while we try to figure out what went wrong with the other phases.  By 22 most of us enter the refinement and continued development stage where we hone the skills that haven’t worked to a fine edge, or consider other possibilities that may prove more valuable.  At 40+ most of us enter the stage that will last the rest of our lives.  Brain researchers call it “continued development of problem finding skills” whatever that means.

During the doing business phase of my brain development, I preferred the 40+ group.  They were generally mellower, knew if they’d made it or weren’t going to, and were more secure with where they were headed and who they were.  Unfortunately, there is a large percentage of people who never make it past the two’s and 14’s.

           

  

Larry Miller: I was born in Los Angeles in 1940. My father was a fighter pilot instructor during WWll and we moved from coast to coast, maybe that’s where I got the nomad in my blood. After graduating from high school in 1958 I joined the Marines. That lifestyle wasn’t for me and upon my discharge I went on with my life, and have never looked back. I worked briefly for a Caterpillar dealer in Riverside, CA before moving back to N. California where I was a welder and truck driver for a chemical company. Truck driving wasn’t my calling anymore than being in the Marines, and I went back to work for another Caterpillar dealer steam cleaning dirty tractor parts and welding. They sent me to schools, lots and lots of schools. I spent as much time going to trade schools as I did at work. I went from cleaning parts to apprentice field mechanic, to mechanic to the parts department to satellite store manager in less than two years. They wanted me to move to Sacramento and be a salesman: I moved to Oregon to learn to commune with nature. I went to work for another heavy equipment dealer and was later contacted by the World’s largest Lorraine Crane dealer and offered the position of purchasing agent and general parts manager. In 1967 I was offered a line of automotive parts and supplies and went into business for myself. My business revolved around eleven race cars that we maintained for others, driving race cars professionally and maintaining high end sports cars. I was a championship and regional champion driver. My business was the largest import parts and service, non dealer, in the state until I sold it in 1979. We went sailing in 79, first to Mexico and then Hawaii. I was an award winning Trans-Pacific sailor and sailor of the year, Hawaii, Island of Kauai. An opportunity presented itself in Hawaii during 1981 and I was back in business, importing Japanese auto body and hard parts. I also felt the pull to write and began freelancing for magazines and newspapers in 1982. My main focus in my articles is, and always has been, health, wellness and fitness. Most of us have heard the saying, “Time is all we have.” I disagree. Our health is all we have, because without our health, we have no time. I was a US Olympic team hopeful in racewalking and held all the records for the state of Hawaii. As a sponsored athlete in my forties, I finished first in nine marathons in a row in my division, qualified for the Ironman® and was the state USCF cycling champion five times in Hawaii and Oregon. Celinda and I were married in 1988 after a three year engagement. We sold our businesses and organic farm and sailed back to Oregon. After our sailboat boat was sold, we moved to Joseph, Oregon, two miles from the trailhead into the Eagle Cap Wilderness. We were caregivers for my mother the last ten years she was alive. We moved to New Mexico in 1995 because it was too cold for my mom in Oregon during the winters. Celinda designed, and I engineered and built our strawbale house. I began writing the weekly health column for a local newspaper in 1996, and still do. In 2000, I took the summer off to do a four month, 4000 mile, hike, bike and kayak odyssey. I’d been writing health, fitness and sports articles since 1982 and the journey produced a full-length, nonfiction, first person adventure book, Yol Bolsun, May There Be A Road, which can be bought from Amazon.com and others over the Internet. The summer of 2001 was spent hiking. kayaking, fishing and exploring the southwest. In 2002 Celinda and I spent the summer in Canada learning the hospitality business at a resort in preparation for doing promotion for the resort in the US. Most of 2003 was spent reestablishing the trees and landscape that had died during the stay in Canada. We had a house sitter and the house sitter had an ex-husband, and that’s a long story. In July of 2004 I did a solo kayak trip on the Snake River, taking pictures, writing articles and pencil sketching the journey. I hope to do another kayak adventure on the Snake River during the summer of 2008, on the section I missed in 2000 and 2004. In 2005, I returned to Canada to the resort where we’d spent 2002. I was supposed to be there for the month of June. I’d contacted people I’d met in 2002 and they came back to Canada to fish, hike and spend time at the resort, Echo Valley Ranch and Spa, while I was there. My one month became five and then it was off to Spain to do the El Camino de Santiago as a travel companion with one of the guests who’d returned to Canada in June. During the summer of 2006 a friend from Ireland, who I’d met in Spain the year before, came to visit in NM and we fished, hiked and explored the White Mountains of AZ. He’d never slept out in the wild in a tent before, and it was quite an experience, for both of us. My newspaper articles were put on the Internet beginning in 2002. I was asked to give public speaking engagements, photo and video presentations, on various subjects for the library in Deming, NM and continue to do so. In 2006 I videoed and produced a DVD for the Smithsonian Institute’s travel exhibit “Between Fences.” NMFILMS had a conference by invitation only, which I attended. While attending the conference, I realized that film making wasn’t what I wanted to do but I still wanted to use my sixteen years of experience and enjoyment of videoing and photography. During the winter of 2005, I discovered that no one on record had ever run from the Arizona border to the Texas border, a distance of 165 miles. During the spring and summer of 2006 I trained for the run and the run was completed in October, 2006. In late 2005, I began building and maintaining websites incorporating all the things I enjoyed about video, photography, travel and the out of doors. 2007 has been a summer of upgrading the home and property which resulted in a downgrading of my enthusiasm for being located in one place. If we don’t like what’s happening in our life, we need to change what we’re doing. Celinda and I are ready to pull up roots and move on. I guess I’ve come full circle. I’m ready to revert back to my childhood, and a nomadic lifestyle.
