Bimanual sequential skills, such as typing, are essential for our modern lives. However, how the brain learns bimanual sequential skills is largely unknown. Bimanual sequential skill requires two essential leanings: bimanual posture control and representing motor sequence. We conducted an fMRI study to investigate the neural basis of bimanual sequential skills like typing, resembled in our ordinary movement. Thirty-five healthy right-handed volunteers practiced visually cued bimanual serial reaction time tasks, including the “mirror” and more difficult “parallel” modes of repeating fixed seque

The oculomotor vergence system controls disjunctive eye rotation of convergence (inwards) and divergence (outwards). Convergence Insufficiency (CI) is a binocular vision disorder that exists in 4-17% of the general population. CI incidence rates increase dramatically to ~50% of patients with persistent post-concussive symptoms (PPCS). Understanding the oculomotor vergence neural system in these groups can lead to improved oculomotor therapeutic interventions.10 binocularly normal vision (BNV) persons (17-22 years old) and 10 PPCS-CI (15-23 years old) participated in this study.
