Voluntary control of unavoidable action.

چکیده
Goal-oriented behavior is usually portrayed to be directly related to incentive values. Underlying mechanisms are thought to include reward-oriented response bias and perceptual sensitivity. A recent electrophysiological study by Minamimoto et al. challenges this view, and reports neural activity in the thalamus that appears to counteract response bias. This type of activity might be crucial for our ability to engage voluntarily in actions that give little or no immediate return, but are necessary in the pursuit of long-term goals.

متن کاملAttention and the readiness for action.
The initiation of voluntary action is preceded by up to 2s of preparatory neural activity, originating in premotor and supplementary motor regions of the brain. The function of this extended period of pre-movement activity is unclear. Although recent studies have suggested that pre-movement activity is influenced by attention to action, little is understood about the specific processes that are...
