Not too long along researchers identified a crucial gene that influenced cell shape and growth. That is to say, researchers discovered that neuron growth and connections are altered by the expression of the srGAP2 gene. What this may lead to are breakthroughs in brain science, and greater understanding of brain development and disorders.
It appears that "neuron networking" is influenced by the expression of srGAP2 - it can interfere or influence connections. This in turn shapes how the brain communicates and operates and a multiplicity of levels.
Below is a link to one of many articles on the related research, and following that is a link to an informative article about neurons that might help put things in perspective.
