Correlation between changes in functional connectivity in the dorsal attention network and the after-effects induced by prism adaptation in healthy humans: A dataset of resting-state fMRI and pointing after prism adaptation

Abstract

It has been reported that it is possible to observe transient changes in resting-state functional connectivity (FC) in the attention networks of healthy adults during treatment with prism adaptation. by using functional magnetic resonance imaging (fMRI) (see “Prism adaptation changes resting-state functional connectivity in the dorsal stream of visual attention networks in healthy adults: A fMRI study” (Tsujimoto et al., 2018) [1].Recent neuroimaging and neurophysiological studies support the idea that prism adaptation (PA) affects the visual attention and sensorimotor networks, which include the parietal cortex and cerebellum.These data demonstrate the effect of PA on resting-state functional connectivity between the primary motor cortex and cerebellum. Additionally, it evaluates changes of resting-state FC before and after PA in healthy individuals using fMRI. Analyses focus on FC between the primary motor cortex and cerebellum, and the correlation between changes in FC and its after-effects following a single PA session. Here, we show data that demonstrate the change in resting-state FC between the primary motor cortex and cerebellum, as well as a correlation between the change ratio of FC and the amplitude of the after-effect.

A brief exposure to rightward prismatic adaptation changes resting-state network characteristics of the ventral attentional system

“…A brief exposure to R-PA modulates resting-state connectivity [33][34][35] and was shown here to predominantly decrease the modularity within VAN. The brevity of the R-PA intervention, contrasts with studies of longer exposure to other therapeutic interventions.…”

“…Using 1.5T fMRI data, Tsujimoto and colleagues performed a seed-based correlation analysis within the attention network and found a significant decrease of connectivity between the right intraparietal sulcus and the right frontal eye field and a significant increase connectivity between the right frontal eye field as well as the right anterior cingulate cortex; this was interpreted as a modulation of DAN within the right hemisphere [33]. In a parallel study, Tsujimoto and colleagues reported a change in resting-state functional connectivity between the primary motor cortex and the cerebellum, which correlated with the amplitude of R-PA aftereffect [34]. Global connectivity was analyzed in a recent 3T fMRI study; R-PA induced a significant decrease in two nodes of the default mode network (DMN) and the left anterior insula.…”

Neural Mechanisms of Prism Adaptation in Healthy Adults and Individuals with Spatial Neglect after Unilateral Stroke: A Review of fMRI Studies

“…The four rsFC studies ( Table 2 ) were reviewed qualitatively [ 56 , 65 , 66 , 67 ]. These four published studies had three HC cohorts, asked different questions (rightward PA vs. control; rightward vs. leftward PA; before vs. after rightward PA), and used different connectivity analysis techniques (e.g., global connectivity, seed-based connectivity, correlation of connectivity strength with behavioral data).…”
