Crossed avoiding reaction: a disturbance of the manual spatial function
1Department of Speech Therapy, Niigata Prefectural Muikamachi Hospital, Japan.
Summary
A patient with brain lesions exhibited a rare crossed avoiding reaction. The left hand struggled to reach objects in right-sided space, suggesting unique hemispheric control of manual space.
Area of Science:
- Neuroscience
- Cognitive Neurology
- Neuroimaging
Background:
- A rare neurological syndrome, the crossed avoiding reaction, involves impaired hand movements.
- Lesions in specific brain regions, such as the corpus callosum and cingulate gyrus, can lead to complex motor deficits.
- Understanding hemispheric specialization is crucial for explaining unilateral spatial neglect and motor control.
