Länk - Geners uttryck i mushjärnan, hur och var
One main system-level finding is that a surprisingly large proportion of the genome is expressed in brain -- around 80 percent of all identified genes. Most of these are expressed in only a relatively small subset of genes ("70.5% of genes are expressed in less than 20% of total cells", not together in the same 20%). In other words, the distribution of gene expression is very broad, with a long tail.
