$Abstract\; :\; The\; Gyrification\; Index\; (GI)\; quantifies\; the\; amount\; of\; folding\backslash nof\; a\; cortical\; surface.\; In\; this\; talk,\; we\; show\; the\; efficiency\; of\; spectral\backslash nanalysis\; to\; perform\; such\; a\; task,\; and\; in\; particular\; we\; explain\; how\; the\backslash ngraph\; windowed\; Fourier\; transform\; can\; be\; used\; as\; a\; tool\; to\; define\; new\backslash nGIs\; with\; multiscale\; properties.\; We\; propose\; two\; different\; GIs\; and\; study\backslash ntheir\; effect\; on\; a\; set\; of\; subjects\; whose\; cortical\; surfaces\; are\; modeled\; with\backslash ntriangular\; meshes.[$
