Relationship between (1) CSENORM(prep) of the target M1 and (2) M1-M1 l-IHiNORM(prep) for young (red triangles) and older adults (black circles). Results are collapsed for both directions (l-IHiNORM(prep)) and bilateral M1 (CSENORM(prep)). Abbreviations: O, Older adults; Y, Young adults; r, Pearson’s r correlation coefficient; ρ, Spearman’s ρ correlation coefficient; CSENORM(prep), modulation of corticospinal excitability during the preparatory period; M1, primary motor cortex; l-IHiNORM(prep), modulation of long latency interhemispheric interaction during the premotor period; *, p < 0.05.
