Hi Ritobrato, Nick already answered your query. Just a small add: the gold standard to use local gyrification index is to compute vertex-wise analyses rather than parcel-wise comparisons. Indeed, lGI at each point already quantifies the gyrification in the surrounding region. As a result, the average lGI in a given cortical region will also reflect to some (minimal) extent the gyrification in the neighboring gyral regions. Hope it helps,
