Practice-related changes in neural activation patterns investigated via wavelet-based clustering analysis.

ABSTRACT:

Objectives

To evaluate brain activation using functional magnetic resonance imaging (fMRI) and specifically, activation changes across time associated with practice-related cognitive control during eye movement tasks.

Experimental design

Participants were engaged in antisaccade performance (generating a glance away from a cue) while fMR images were acquired during two separate test sessions: (1) at pre-test before any exposure to the task and (2) at post-test, after 1 week of daily practice on antisaccades, prosaccades (glancing toward a target), or fixation (maintaining gaze on a target).

Principal observations

The three practice groups were compared across the two test sessions, and analyses were conducted via the application of a model-free clustering technique bas
