▁steps ▁than ▁just ▁the ▁on set ▁of ▁brain ▁activity . ▁The ▁bearing ▁of ▁these ▁results ▁upon ▁not ions ▁of ▁free ▁will ▁appears ▁complex . A ▁brief ▁discussion ▁of ▁possible ▁interpretation ▁of ▁these ▁results ▁is ▁found ▁in ▁▁ ▁Some ▁argue ▁that ▁placing ▁the ▁question ▁of ▁free ▁will ▁in ▁the ▁context ▁of ▁motor ▁control ▁is ▁too ▁narrow . ▁The ▁ob jection ▁is ▁that ▁the ▁time ▁scales ▁involved ▁in ▁motor ▁control ▁are ▁very ▁short , ▁and ▁motor ▁control ▁involves ▁a ▁great ▁deal ▁of ▁un cons cious ▁action , ▁with ▁much ▁physical ▁movement ▁entirely ▁un cons cious . ▁On ▁that ▁basis ▁"... ▁free ▁will ▁cannot ▁be ▁s que ez ed ▁into ▁time ▁frames ▁of ▁ 1 5 0 – 3 5 0 ▁ms ; ▁free ▁will ▁is ▁a ▁longer ▁term ▁phenomen on " ▁and ▁free ▁will ▁is ▁a ▁higher ▁level ▁activity ▁that ▁" c annot ▁be ▁captured ▁in ▁a ▁description ▁of ▁neural ▁activity ▁or ▁of ▁mus cle ▁activation .... " ▁The ▁bearing ▁of ▁timing ▁experiments ▁upon ▁free ▁will ▁is ▁still ▁under ▁discussion . ▁ ▁More ▁studies ▁have ▁since ▁been ▁conducted , ▁including ▁some ▁that ▁try ▁to : ▁ ▁support ▁Lib et ' s ▁original ▁find ings ▁ ▁suggest ▁that ▁the ▁can cell ing ▁or ▁" vet o " ▁of ▁an ▁action ▁may ▁first ▁arise ▁sub cons ci ously ▁as ▁well ▁ ▁explain ▁the ▁underlying ▁brain ▁structures ▁involved ▁ ▁suggest ▁models ▁that ▁explain ▁the ▁relationship ▁between ▁conscious ▁intention ▁and ▁action ▁ ▁Benjamin ▁Lib et ' s ▁results ▁are ▁quoted ▁in ▁favor ▁of ▁e pi phen omen al ism
