|The main challenge when it comes to understanding the human brain is the fact that it is the most powerful computer known. It consists of about 100 billion neurons with roughly 1 quadrillion (1 million billion) connections wiring these cells together, and each connection or synapse typically fires about 10 times per second. Genetic activity was remarkably similar between the two complete brains. This suggested a strong underlying common genetic blueprint for the human brain. About half of all genes active in the brain have been poorly studied 'The fact that so many of the brain-expressed genes have not been well-characterized means that there are huge voids in our understanding of how genes relate to proper brain function.' 'Many of these genes are used in highly selective ways - in particular structures and cell types - and this map we have created can provide functional predictions...|
