Functional network activity during errorless and trial-and-error color-name association learning.

ABSTRACT:

Introduction

In cognitive rehabilitation, errorless (EL) and trial-and-error (T&E) learning are well-known methods, but their neural mechanisms are not well known. In this study, we investigated functional magnetic resonance imaging data for healthy adults during EL and T&E learning.

Methods

Participants memorized color-name associations in both methods using Japanese traditional colors which were unfamiliar to study participants. A functional network analysis was conducted by applying graph theory. We focused on two major cognitive networks: the default mode network (DMN) and the fronto-parietal network (FPN). Also, we used "within-network connectivity" and "between-network connectivity" graph metrics. The former represents the functional connectivity strength of a subnetwo
