Modern brain mapping – what do we map nowadays?
The problem of functional localization in the brain is one of the most fundamental in neuroscience. For this problem two opposite ideologies: "modular" versus "holistic" nature of the brain also known as "localism" and "holism" have been discussed for a long time (Flourens 1825; Luria 1967). The debate in favor of one or another ideology still can be traced at all methodological levels - from a cell to a system. In this opinion paper we want to raise a question - what is nowadays meant by mapping of the brain? In addition we want to highlight the necessity of being aware of occasionally occurring discontinuity in the research at different methodological scales.
