Observation of auditory perceptual and visuo-spatial characteristic of a patient with hemangiopericytoma in occipital lobe: a magnetoencephalography (MEG) study

Observation of auditory perceptual and visuo-spatial characteristic of a patient with hemangiopericytoma in occipital lobe: a magnetoencephalography (MEG) study

The present study discussed functional reorganization and alteration in respond to the slow-growing tumour, hemangiopericytoma in the occipital cortex. Visual evoked field (VEF) and auditory evoked field (AEF) using magnetoencephalography (MEG) was used to evaluate the source localization and brain...
