Task-specific ISS reduction and network balance during Stroop task performance in older adults

Kazuya Ouchi, Haruki Yokota, Narihisa Matsumoto, Tomokazu Tsurugizawa

This study examines age-related changes in functional connectivity during the Stroop task using fMRI and Bayesian hierarchical modeling, finding reduced inter-subject similarity and specific spatial reorganization in older adults.

Age-related alterations in functional and structural networks in the brain in macaque monkeys

Kazuya Ouchi, Shinya Yamamoto, Makoto Obara…·Tomokazu Tsurugizawa

This study examines age-related changes in functional and structural networks in macaque monkeys, finding decreased structural connectivity and increased functional connectivity and amplitude of low-frequency fluctuations with age.
