Research on the neural basis of consciousness has largely focused either on where and when neural activity represents conscious contents, or on the interactions through which distributed neural populations become integrated. We argue that these approaches can be connected by analysing information relations among neural representations. A perceptual content can be synergistic when it is carried...
Hierarchy is a major organizational principle of the cortex and underscores modern computational theories of cortical function. The local microcircuit amplifies long-distance inter-areal input, which show distance-dependent changes in their laminar profiles. Statistical modeling of these changes in laminar profiles demonstrates that inputs from multiple hierarchical levels to their target areas...
