Adolescence brain scanning grey-matter neural connections prefrontal cortex white matter

  • Jay Giedd at the National Institute of Mental Health in Bethesda, Maryland, and his colleagues have followed the progress of nearly 400 children, scanning many of them every two years as they grew up. They found that adolescence brings waves of grey-matter pruning, with teens losing about 1 per cent of their grey matter every year until their early 20s (Nature Neuroscience, vol 2, p 861).
  • This cerebral pruning trims unused neural connections that were overproduced in the childhood growth spurt, starting with the more basic sensory and motor areas.
  • Among the last to mature is the dorsolateral prefrontal cortex at the very front of the frontal lobe. This area is involved in control of impulses, judgement and decision-making, which might explain some of the less-than-stellar decisions made by your average teen. This area also acts to control and process emotional information sent from the amygdala - the fight or flight centre of gut reactions - which may account for the mercurial tempers of adolescents.

  • These changes have both benefits and pitfalls. At this stage of life the brain is still childishly flexible, so we are still sponges for learning. On the other hand, the lack of impulse control may lead to risky behaviours such as drug and alcohol abuse, smoking and unprotected sex.
  • As grey matter is lost, though, the brain gains white matter
  • Substance abuse is particularly concerning, as brain imaging studies suggest that the motivation and reward circuitry in teen brains makes them almost hard-wired for addiction.
  • since drug abuse and stressful events - even a broken heart - have been linked to mood disorders later in life, this is the time when both are best avoided.
  • Making the most of this time is a matter of throwing all that teen energy into learning and new experiences - whether that means hitting the books, learning to express themselves through music or art, or exploring life by travelling the world.

    The Healthy Brain Program, an initiative of the Brain Foundation, aims to assist Australians to keep their brains healthy into old age, through the provision of community education and research. The program aims to address issues such as: People are living longer, and the prevalence of degenerative brain disorders is increasing. There is little information available about how to keep the brain healthy compared to the wealth of information about a healthy body and heart. There is a need for a coordinated approach to education on key indicators and risk reduction strategies.

    It's good for your life and health to be optimist.

    It' s a slightly different perspective that I' m enjoying at this time but I appreciate it may only be true for some-I' ve just begun to understand what "faith" means tho I' m not religious-still! (I feel some empathy now as to why people are) I feel much more inclined to just sit still and connect inside with the Source of me-any meditation or spiritual practice can lead me there or creativity,music too,nature! But to deliberately connect to the part of us all that is connected and knows/is All. From that place I' ve understood that theres noone to be, nowhere to go, nothing to do as we are all there already as we are all IT! So of course daily I forget this but this insight has gifted me much more optimism as I can assume that whatever I really ask for/intend/desire is already in the big melting pot that we can Life/God. That is ' faith' Ive realised now- to ask and know intimately that it' s already a given and to STOP Worrying and completely ignore the naysayers etc. It' s really trusting that I' m connected to it all and I am not separate. I' m beginning to observe quite distinctly the thoughts that separate me from what I want/intend. Particularly in relation to my fellow beings! But then I turn to the place that is connected and I feel so good! and just thinking of the situation from that place and holding that good feeling in relation and giving it over (the problem) really helps! I know several spiritual teachers have said "give it over to me". I' m starting to understand it really is that simple. Trying hard and worrying just create such muck and mire! This may be part of the surrender letting go and letting God that others speak of also? I reckon it would be interesting to see where how people get there faith/trust in life that creates the underlying optimism. What gives that to them? I remember as a child I had it naturally I often got what I asked for and intended and there was an abundance of flow and optimism. No resistance. Fear and doubt come later
