A chilling new technique shows the intricate and coordinated activity of previously mysterious pieces of the synapse, the all-important junction between neurons that allows cells to talk to each other.The close-ups are so striking, they made the cover of the 11 January Journal of Cell Biology.To capture this pretty picture, the researchers used a complex technique called electron cryotomography. They first froze rat brain cells in action at temperatures as low as -165 degrees Celsius, then looked at the cells at different angles using an electron microscope and, finally, reconstructed them in three dimensions on a computer.Read more at...SFARI, February 2010.
