FAQ
Frequently Asked Questions
No. For approximately 95% of right-handed people and 70% of left-handed people, the left hemisphere is dominant for language. However, a significant minority, particularly left-handers, may have right-hemisphere or mixed dominance.
Yes. The concept of hemispheric dominance applies to specific functions. For example, the right hemisphere is often dominant for visuospatial processing, facial recognition, and certain aspects of emotion. The term 'dominant hemisphere' without qualification usually refers to language dominance.
Damage to the language-dominant hemisphere (often from stroke or trauma) can result in aphasia (language impairment), apraxia (difficulty planning movements), and acalculia (problems with calculations). Recovery may involve neuroplasticity, where other brain regions take over some functions.
It is determined through clinical tests (e.g., Wada test, where one hemisphere is temporarily anaesthetised), functional neuroimaging (fMRI, PET scans during language tasks), or behavioural assessments of patients with brain lesions.
