Specificity Versus Generality of (Visual) Cortex

Today, we think of the brain as a neural network. But is this a rather general purpose network where more or less every part can provide the same capabilities, or is it made up from highly specialized subsets that all contribute a specific function? Patient studies show rather specific disorders (for example for reading), but on the other hand sometimes large structural defects without any obvious symptoms. In fMRI we define regions of interest but are aware that quite a number of areas increase their blood flow outside these ROIs. Histology of cortex differs clearly between areas, but there are people who pretend analyzing in detail a small part of cortex will reveal the function of cortex as such.
The aim of the conference is to better clarify the amount of specificity that should be expected and to ask what may be the exact contributions of individual subareas - maybe we are just asking the wrong questions when we expect areas to be specific for "colour" or "motion".
