Information-Theoretic Quantification of Dedifferentiation in the Aging of Motor and Executive Functions

Using information-theoretic measures, this study quantifies how neural specificity (differentiation) of motor and executive functions declines with age — shedding light on the mechanisms of cognitive aging.

Relationship Between Mode of Sport Training and General Cognitive Performance

This study compares general cognitive performance across athletes trained in open-skill sports (requiring reactive, unpredictable responses) versus closed-skill sports (stereotyped, self-paced), finding that open-skill training is associated with superior attention switching and executive flexibility.

Effects of Aerobic Training Intensity on Executive Functions in Middle-to-Old Age Adults

Comparing moderate versus vigorous aerobic training, this study examines how exercise intensity differentially benefits executive function components — including working memory, cognitive flexibility, and inhibitory control — in middle-to-old age adults.
