How the two sides of the brain function so differently
Jill Bolte Taylor is a Harvard-trained neuroanatomist who experienced a severe bleed in the left hemisphere of her brain in 1996. By the afternoon she could not walk, talk, read, write, or recall any of her life. It took eight years for her to completely recover all of her physical function and thinking ability. This 18 minute talk from 2008 was given twelve years after her experience. Such was the impression she made it was the first TED talk to go viral on the Internet:
This is a deeply personal account of what it is like to experience a sudden stroke. As the left side of her brain became increasingly affected she suddenly lost the familiar 'brain chatter' we all experience and she was plunged into inner silence. She writes:.....
How the left brain has come to dominate Western culture
You can make a pretty strong case for saying that the human brain is the most complex object in the entire universe. It contains 100 billion nerve cells (called neurones). Each of these neurones contains a vast electrochemical complex and powerful micro-data-processing system. As complex as each cell is it would fit on the head of a pin! And in spite of all the research in the last century there is much we still do not understand.
Someone who has thought about this a lot is Iain McGilchrist. He is a psychiatrist, doctor, writer and former Oxford literary scholar. (We were also contemporaries at medical school in Southampton in the 1980s, but our paths did not often cross). In this fascinating animated 11 minute lecture from the Royal Society of Arts McGilchrist explains the main themes from his book, "The Master and His Emissary". It is about the functioning of the human brain. His in depth training in both the arts and sciences makes him uniquely qualified to write on this subject.
McGilchrist has produced a huge masterpiece, and this article and video can only give a simple broad overview. However, one of his key points is that the implications of brain science are highly significant in understanding the development of Western culture.
The main focus of discussion is around the two cerebral hemispheres. By carefully reviewing over 50 years of brain research McGilchrist explains how a simplistic understanding of the left side being just concerned with, for example, reason and language and the right side just with emotion and visual imagery is too simplistic. Both sides of the brain have elements of these abilities, but it is also true that there is a significantly greater emphais of function on one side compared to the other. The purpose of the corpus callosum that connects the two sides of the brain is to inhibit the over emphais of one side of the brain. However, the corpus callosum has been shown to have got less influential over time and the left hemisphere has become in our day and age much more dominant.
Dr John Geater is at the time of writing aged 73. He is married to Jane and has three adult children. He is a medical doctor and has worked in Bhutan, New Zealand and in England. In 2006 he received an MBE from the Queen for his work in setting up the postgraduate medical education charity, PRIME (Partnerships in International Medical Education). He has taught holistic medical education in 26 different countries around the world. Just before Christmas 2017 he was diagnosed with metastatic pancreatic cancer.
Do join us in this fascinating podcast conversation as we discuss John's life and explore questions such as:
How do you respond when bad things happen to you?
How do you make sense of being diagnosed with cancer three times in your life?
How to embrace life's mysteries when things don't go the way you want or expect.
We also ask John:
What was it like running a leprosy hospital in Bhutan at the age of 25?
What would you say to someone who has a terminal illness and is scared?
To explore with us from Bronnie Ware's book the five regrets of the dying:
I wish I lived a life true to myself and not what was expected of me.
I wish I had not worked so hard.
I wish I'd had the courage to express my feelings.
I wish I had stayed in touch with my friends.
I wish I had let myself be happier.
What he is looking forward to in the life to come?
It is a commonly held assumption among many people that faith in God is incompatible with a scientific world view. Our largely secular media would have us believe that science and faith in a universal creator God is an irreconcilable contradiction. (See We're All Materialists Now!).Yet the more closely you examine the evidence the more you realise this does not have to be the case at all.
Brian Enderle holds graduate degrees in both science and theology. In this 13 minute TED talk he explains how scientific understanding of the universe is even more amazing and fantastic than we could ever imagine.
The more you look at the findings the harder it is not to use hyperbole and extreme descriptions. Take the finding of how much of atoms are empty space. In case you were wondering a single atom is apparently a million times smaller than a human hair. Within an atom there is, according to Enderle, 99.9999999999999% empty space! That means everything around us that appears solid, physical and real is actually practically all empty space! We assume because atoms are so tiny and so numerous objects appear solid to us, but in fact they are not!
"I need more time!" How often have you said that to yourself? Its frequently how I feel. So much to do and apparently so little time to do what needs to be done. And yet when I have found myself with more time available, I've also found myself too exhausted or distracted to make significant headway with the different projects that I have told myself are important to me. When that happens it is easy to feel guilty or be too hard on oneself. Maybe part of the reason for this is because it is more then than just a time issue.
Part of the problem comes because we don't grasp that we have overloaded ourselves in a number of different ways. Talking about needing more time is way too simplistic.
Here are some examples. I am guilty of all of them on one occasion or another:
Everyone seems agreed that we live in an overwhelming world with far too much to do and too little time to do what needs to be done. With our busy frenetic lifestyles there is always one more email to write, one more phone call to make, or one more task that could be done. Our electronic devices never switch off and we can feel the same way. The more productive I become then the more work I create for myself! I can feel like the proverbial hamster on a wheel going faster and faster just to keep still.
But could there be a better way? Could the secret to better productivity be found not in getting even faster, and doing more and more, but in learning to rest better?
Its more than likely that you, the reader, is a knowledge worker who has to produce results not physically with your hands and manual labour, but with your mind and greater clarity of thinking. However, there are certain assumptions that govern the way we look at how we produce as knowledge workers. Here are three assumptions we make. We assume:
knowledge is produced rather than discovered or revealed.
The amount of work that goes into an idea determines how important it is.
The creation of ideas can be organised and systematised.
The results of such thinking is:
We think of over-work as a virtue
We believe hard labour rather than contemplation is the source of great ideas and breakthroughs.
We assume success comes from being hard driven and work-obsessed to the exclusion of everything else.
So when it comes to rest, who has got the time for that?
Here are three surprising insights about rest that have also been confirmed by experience and neuroscience:...
So much to do and so little time to do it! That seems like the cry and experience of our day and age. With such an explosion of choice there is no limit it seems to what I can, have, do and fill my time with. But where do I put the limits? Should there be limits? How do I decide what is really important or trivial? What should I do now or leave for another day or time? That is why the concept of margin is so vital.
For me with a recent fracture of my wrist, and needing to take time off work, I have had to slow myself down considerably. What seemed urgent and essential on one occasion feels less so now. At the same time I have started to slowly appreciate the importance of having margin or space in my life. It is something I find myself continually having to remind myself about. As my pace gradually begins to pick up I am reminded of the words of King Solomon (who certainly had a lot to occupy and distract him!), "Better one hand with tranquility than two handfuls with toil and chasing after the wind." (Ecclesiastes 4:6)
I now suspect it was bound to happen sooner or later. I was recently on a skiing holiday and managed to break a bone in my left arm.
As I write this I am plastered up with a sling and can just about type with a single finger! At this point it would be so easy to get frustrated and disappointed with life, myself and the universe.
I could ask myself questions like, "Why am I such a bad skier? Why did I allow myself to go on that slope? Why did I not stay back that afternoon and rest rather than going out to ski again? How am I going to deal with all the inconvenience and hassle this will cause? I haven't got time to be unwell. Haven't I got more important things to do than just stop to recover? What have I done to deserve this?"
The problem with questions like that is they are focused on the past or outside of anything I can control. They put me at risk of getting into a negative defeatist spiral. By putting me in a victim mindset they can so easily lead to depressive thinking.
The human brain is so powerful that asking questions like that to myself will only cause me to find reasons to reinforce my situation. In other words what you focus on will only get bigger. Argue for your limitations and you will invariably be right. Argue for your possibilities and options, then you will be right as well. The choice is yours. There is a much better way. This does not just apply to skiing accidents, but to so much else in life.
Fortunately I was able to not go down that negative road and instead ask myself a better, more future focused question: What does this now make possible?
In addition to that I was able to join that question with two true statements:...
I have a friend who over 10 years ago made a serious suicide attempt. His wife had called me at around 8.30am saying he had left home very early without speaking to her. She knew he had a lot on his mind and was worried about him. He had not responded to her repeated calls or texts. He was not at his office. We agreed the police needed to be called. Thankfully his attempt was unsuccessful and all these years later he is in a much more positive place.
Sadly that is not the case for the people mentioned in this short 1 minute video below:
The tragic fact is that 84 men commit suicide in the UK every week. Suicide is the leading cause of death in the UK for those under 50.
