Yesterday the journals Science, Science Advances, and Science Translational Medicine, printed 21 articles reporting the results of a 5 year long $375 million federally funded project to map the human brain. The researchers discovered there are 3,300 different types of brain cells in the human brain and showed how they change from the womb to adulthood. They found that 16,000 genes are active in the brain and different combinations of those genes are active in the different cell types, they also found some differences in activation among different individual humans. All the cell types have counterparts in chimpanzees and gorillas, and only a few hundred genes are different, but those genes are involved in the construction of the synapse which connects one neuron to another, or are related to master switches that turn many other genes on or off. Most areas of the brain contain the same types of cells although their proportions vary, an exception is the visual cortex which has some cell types not seen elsewhere.
