Summary
A patient temporarily experienced mirror writing and reading after brain surgery. This suggests the right hemisphere may play a role in processing mirror-image text.
Area of Science:
- Neuroscience
- Cognitive Psychology
- Neurology
Background:
- Surgical removal of a left parietal meningioma can lead to transient neurological deficits.
- Mirror writing and reading are rare phenomena that can occur after brain injury or surgery.
Observation:
- A 74-year-old right-handed woman exhibited temporary mirror writing and reading post-surgery.
- Tachistoscopic hemifield stimulation revealed right hemisphere superiority in recognizing mirror-image words.
Findings:
- The study observed a temporary deficit in reading and writing, specifically mirror-image processing, in a patient after meningioma removal.
- Neuropsychological testing indicated a right hemisphere dominance for processing mirrored text.
Implications:
- The findings support the hypothesis of bihemispheral mirror-image engrams for explaining such phenomena.
- This case contributes to understanding hemispheric lateralization in visual-spatial and linguistic processing.
