I have read that greater intelligence is associated with the volume of grey matter in particular regions of the cortex. I have read that that the way the volumes of grey matter are distributed over the brain is highly hereditary. I have also read (this bit I interpreted a bit so I could be wrong) that if the patterns of 'wiring' in these regions is set up in a particular way it can be efficient ... so a person with lower volume of grey matter but 'better' wiring might be still be as intelligent as a person with more volume but 'poorer' quality of wiring. Finally I have found out that you can build more synapse by employing more critical thinking and alternative thinking in solving problems. So intelligence could be factored in because you are adding more wiring. Is more wiring the same as 'better quality' of wiring? I'm not sure but maybe. What do people think? some of the other tips are Meditation using a buddhist technique, which is shown to boost the grey matter associated with attention: I got this from sci-con.org/2006/02/meditation-may-increase-the-thickness-of-the-cortex/ and following the suggestions outlined in this article: www.sciencedaily.com/releases/2006/05/060522150621.htm help. Finally I have read it is possible to create neurons using stems cells in a culture. This has been done in labs. So is it possible to 'hook up' cultured neurons via some kind of interface to your cortex so you simply add more processing capacity...like adding more RAM. Has this been done? Is this possible? I am not sure how the brain would be able to adapt to this, would it send out blood vessels and the supporting stuff like astrocytes to nourish these newly added neruons?
