Columnar processing in primate pFC: evidence for executive control microcircuits.

abstract：:The putative independence of cortical mechanisms for color, form, and motion raises the binding problem-how is neural activity coordinated to create unified and correctly segmented percepts? Binding could be guided by stimulus-driven correlations between mechanisms, but the nature of these correlations is largely unex...
