Though fanciful, the payoff could be profound. Map out our "connectome" – following other major "ome" projects such as the genome and transcriptome – and we will lay bare the biological code of our personalities, memories, skills and susceptibilities. Somewhere in our brains is who we are.
To use an understatement heard often from scientists, the job at hand is not trivial. Lichtman's machine slices brain tissue into exquisitely thin wafers. To turn a 1mm thick slice of brain into neural salami takes six days in a process that yields about 30,000 slices. | guardian.co.uk
