Traces of learning in the cerebral cortex

The mammalian brain, with its immense number of neurons and extreme density of communication, is the most complex network we know. Methods for partial and sparse analysis of these networks exist for more than a hundred years. However, obtaining locally complete wiring maps of neuronal networks in the mammalian brain only became possible a few years ago. Our research team has now succeeded in mapping brain tissue from the mammalian brain and analyzing it for traces of previous learning processes.
