“…Damage to the cortical regions immediately around a lesion, the white matter at the depths of the lesion, and the brain tissue implicated in the surgical approach can all result in a new deficiency. Understanding the anatomical and physiological link between a lesion and the surrounding expressive brain tissue is essential to minimally morbid surgery [3,4]. Functional brain imaging reveals the anatomic localization of several brain processes, including movement, sensation, speech, and memory, as well as the white matter networks bridging important regions.…”
