I was extremely happy and thrilled by the media reports last week on the push by Obama administration to fund a major project to elucidate a complete map of neuronal activity in the brain. This Brain Activity Mapping (BAM) will certainly help us understand the details of many of the functions of this most mysterious organ in our body. As it has been pointed out by several scientists, a complete map may still not explain everything about the brain. For instance, it may not tell us what consciousness is, but it will certainly help us design experiments to find answers to questions that until recently many thought would never be answered. This reminds of the 70s, when many scientists thought sequencing the genome would be impossible until two great molecular biologists, Sanger and Gilbert came up with some clever tricks to sequence pieces of DNA.
I believe, there is nothing in the known universe that is more complex and difficult to study than this three pound tissue inside our head. BAM has special significance to me since my book ‘Slaves To Neurons’ – a science fiction – is all about mapping the electrical pathways in the brain as we go through our daily activities. I have mentioned in several of my blogs and tweets that the technology I envisioned in my book would be a reality within forty to fifty years. The initiative for BAM will go a long way to make this prediction come true.
