▁As ▁mentioned ▁above , ▁E EG ▁is ▁very ▁useful ▁in ▁analysis ▁of ▁imm obile ▁patients , ▁typically ▁during ▁the ▁sleep ▁cycle . ▁While ▁there ▁are ▁other ▁types ▁of ▁research ▁that ▁util ize ▁E EG , ▁E EG ▁has ▁been ▁fundamental ▁in ▁understanding ▁the ▁rest ing ▁brain ▁during ▁sleep . ▁There ▁are ▁other ▁potential ▁uses ▁for ▁E EG ▁and ▁M EG ▁such ▁as ▁chart ing ▁re h abil itation ▁and ▁improvement ▁after ▁tra uma ▁as ▁well ▁as ▁testing ▁neural ▁conduct ivity ▁in ▁specific ▁regions ▁of ▁ep ile pt ics ▁or ▁patients ▁with ▁person ality ▁dis orders . ▁ ▁Ne ur om od ulation ▁can ▁involve ▁numerous ▁techn ologies ▁combined ▁or ▁used ▁independently ▁to ▁achieve ▁a ▁desired ▁effect ▁in ▁the ▁brain . ▁Gene ▁and ▁cell ▁ther apy ▁are ▁becoming ▁more ▁pre val ent ▁in ▁research ▁and ▁clin ical ▁tri als ▁and ▁these ▁techn ologies ▁could ▁help ▁st unt ▁or ▁even ▁reverse ▁disease ▁pro gression ▁in ▁the ▁central ▁nerv ous ▁system . ▁Deep ▁brain ▁stim ulation ▁is ▁currently ▁used ▁in ▁many ▁patients ▁with ▁movement ▁dis orders ▁and ▁is ▁used ▁to ▁improve ▁the ▁quality ▁of ▁life ▁in ▁patients . ▁While ▁deep ▁brain ▁stim ulation ▁is ▁a ▁method ▁to ▁study ▁how ▁the ▁brain ▁functions ▁per ▁se , ▁it ▁provides ▁both ▁sur ge ons ▁and ▁ne uro log ists ▁important ▁information ▁about ▁how ▁the ▁brain ▁works ▁when ▁certain ▁small ▁regions ▁of ▁the ▁bas al ▁gang lia ▁( n uc lei ) ▁are ▁stim ulated ▁by ▁elect rical ▁curr ents . ▁ ▁Future ▁techn ologies ▁The ▁future ▁of ▁ne uro
