▁relatively ▁new ▁field ▁that ▁comb ines ▁the ▁use ▁of ▁ne uro dev ices ▁and ▁ne uro chem istry . ▁The ▁basis ▁of ▁this ▁field ▁is ▁that ▁the ▁brain ▁can ▁be ▁reg ulated ▁using ▁a ▁number ▁of ▁different ▁factors ▁( met abol ic , ▁elect rical ▁stim ulation , ▁phys i ological ) ▁and ▁that ▁all ▁these ▁can ▁be ▁mod ulated ▁by ▁devices ▁impl anted ▁in ▁the ▁neural ▁network . ▁While ▁currently ▁this ▁field ▁is ▁still ▁in ▁the ▁research er ▁phase , ▁it ▁represents ▁a ▁new ▁type ▁of ▁techn ological ▁integration ▁in ▁the ▁field ▁of ▁ne uro techn ology . ▁ ▁The ▁brain ▁is ▁a ▁very ▁sensitive ▁organ , ▁so ▁in ▁addition ▁to ▁research ing ▁the ▁amaz ing ▁things ▁that ▁neur om od ulation ▁and ▁impl anted ▁neural ▁devices ▁can ▁produce , ▁it ▁is ▁important ▁to ▁research ▁ways ▁to ▁create ▁devices ▁that ▁el ic it ▁as ▁few ▁negative ▁responses ▁from ▁the ▁body ▁as ▁possible . ▁ ▁This ▁can ▁be ▁done ▁by ▁modifying ▁the ▁material ▁surface ▁chem istry ▁of ▁neural ▁impl ants . ▁ ▁Cell ▁ther apy ▁Research ers ▁have ▁begun ▁looking ▁at ▁uses ▁for ▁stem ▁cells ▁in ▁the ▁brain , ▁which ▁recently ▁have ▁been ▁found ▁in ▁a ▁few ▁lo ci . ▁A ▁large ▁number ▁of ▁studies ▁are ▁being ▁done ▁to ▁determine ▁if ▁this ▁form ▁of ▁ther apy ▁could ▁be ▁used ▁in ▁a ▁large ▁scale . ▁Exper iments ▁have ▁successfully ▁used ▁stem ▁cells ▁in ▁the ▁bra ins ▁of ▁children ▁who ▁suffered ▁from ▁inj uries ▁in ▁gest ation ▁and ▁elder ly ▁people ▁with ▁deg ener ative
