Neurogenesis

n e u r o g e n e s i s

Your Brain is always changing.

 

The Brain, your Brain, is, incredibly enough, the most complex object in the known Universe!

You have around 100 Billion Neurons and each one connects with up to 10,000 other neurons, generating a network of unparralleled complexity.

 

Untill around the end of the last century, the general scientific concensus was that we are born with the maximum number of neurons we will ever have, and that while synapses may multiply, it was the fate of our neurons to gradually wither and die.

 

This view has now been reversed and, primarily due to the emergence of new imaging techniques, it is fully accepted that new interneuron connections can be made and new neurons can be grown throughout life, even existing neurons can take on new functions when the need arises.

This has lead to the fields of Neurogenesis (growing new Neurons) and Neuroplasticity (Altering Neuron structure in response to stimulus) .

 

In much the same way as Epigenetics gives us much greater possible control over who we are through controlled gene expression, Neurogenesis allows us to consider that our brain can, and will, grow and adapt to the stimuli it is exposed to, and hence that our sense of self and our capabilities are variable according to self development strategies which we can choose to adopt.

Our Brains and our Genes are factors which we can influence and develop, you can influence who you are.

 

Opening up the possibility that even as our model of the Brain advances, we may have really very little idea of how and what it is for is this extraordinary report in the The Lancet of a normal man with a Brain that is 75% fluid...a massive expansion of the Lateral Ventricles which contain Cerebrospinal fluid, a 92% Water Plasma liquid which envelopes the Central Nervous System, and yet he leads a normal life..

 

These paradigm changes reveal to us that scientific knowledge is in constant evolution, unchallengeable beliefs in how things work have crumbled to dust in the last 20 years opening the way for the emergence of new understanding.

Here is a stunning video from Stanford University giving us a gimpse of the beautiful complexiy of the human brain

This video below gives us an animated glimpse of what happens as we learn new skills...generating new neuronal connections inside the brain, so the brain is infinitely adaptable according to the stimulus it recieves. What becomes extraordinarily interesting is the manner in which the Neurons axons grow towards their destination synaps...extending out like brances in space they orientate themselves in an intentional manner towards the completion of a synaptic junction which 'hard wires' the learning, making it easier in the future ..
