Intra-operative cortical motor mapping using subdural grid electrodes in children undergoing epilepsy surgery evaluation and comparison with the conventional extra-operative motor mapping

Epilepsy surgery can be highly effective and associated with favourable cognitive, functional and seizure-free outcomes in carefully selected patients.(Dwivedi et al., 2017) Epileptogenic foci in children with epilepsy are commonly extra-temporal and may be in close proximity to eloquent areas, such as the motor cortex. Thus, it is vital to accurately map the motor cortex to prevent post-operative motor deficits.
