Psience Quest

Quote:The more we learn about genetics and the brain, the more impossibly complicated both reveal themselves to be. We have picked no low-hanging fruit after three decades and $50 billion because there simply is no low-hanging fruit to pick. The human brain has around 86 billion neurons, each communicating with thousands of others via hundreds of chemical modulators, leading to trillions of potential connections. No wonder it reveals its secrets only very gradually and in piecemeal fashion.

Genetics offers the same baffling complexity. For instance, variation in more than 100 genes contributes to vulnerability to schizophrenia, with each gene contributing just the tiniest bit, and interacting in the most impossibly complicated ways with other genes, and also with the physical and social environment. Even more discouraging, the same genes are often implicated in vulnerability to multiple mental disorders – defeating any effort to establish specificity. The almost endless permutations will defeat any easy genetic answers, no matter how many decades and billions we invest.

The NIMH has boxed itself into a badly unbalanced research portfolio. Playing with ‘cool’ brain and gene research toys trumps the much harder and less intellectually rewarding task of helping real people.

Contrast this current NIMH failure with a great success story from NIMH’s distant past...
