Preparing for action reduces the need for reactive fronto-basal ganglia communication to gate voluntary actions [180]. The neural substrates of proactive inhibitory control might also vary with task content [181]. Given these findings, voluntary control can no longer be viewed as an all or none phenomenon. how many seats are up for senate https://ajliebel.com
