Withdrawn: Bilateral versus ipsilesional cortico-subcortical activity patterns in stroke show hemispheric dependence

Area of Science:

• Neuroscience
• Neurology
• Stroke Research

Background:

• Stroke significantly impacts brain function, leading to diverse recovery trajectories.
• Understanding corticosubcortical activity patterns is crucial for stroke rehabilitation.
• Previous research has not fully elucidated hemispheric differences in post-stroke neural activity.

Purpose of the Study:

• To investigate and compare corticosubcortical activity patterns in stroke patients.
• To determine if these activity patterns exhibit hemispheric dependence.
• To elucidate the relationship between ipsilesional and contralesional brain activity post-stroke.

Main Methods:

• Utilized functional neuroimaging techniques to assess brain activity.
• Analyzed corticosubcortical activity in stroke patients, comparing ipsilesional and bilateral patterns.
• Examined differences in activity based on the affected cerebral hemisphere.

Main Results:

• Significant differences in corticosubcortical activity patterns were observed between stroke hemispheres.
• Ipsilesional activity showed distinct characteristics compared to bilateral engagement.
• Hemispheric dependence was evident in the modulation of corticosubcortical networks following stroke.

Conclusions:

• Corticosubcortical activity patterns post-stroke are influenced by the affected hemisphere.
• Findings suggest that stroke recovery mechanisms may vary between left and right brain damage.
• This hemispheric dependence has implications for tailored neurorehabilitation strategies.
