Here is a nice interview with Jeff Lichtman of Harvard, who is working on a cellular-level map of synaptic connections in the brain (a connectome). The interview raises several questions, like how can we collect thousands of petabytes (millions of gigabytes) of data of the structure of the brain at the level of individual cells? Do we even need so much data? Even though connectomics won't reveal much about neural dynamics (i.e. how neurons actually transmit or integrate information), it should be a useful tool for further work in theoretical neuroscience. Someone has to do it. One caller in this interview asks a great question on the hard problem of consciousness: when scientists look at neuronal activity when one is thinking of a childhood pet, where in the universe is that image of the dog? All the scientists see, after all, is electrical activity...
