When participants utilize prime information to prepare some or all aspects of the forthcoming movement, reaction time (RT) costs are obtained when the imperative response signal demands an unexpected rather than an expected movement.
Regular corporeal patterns demand less energy to imitate, due to the lack of timely adjustments within the kinetic pattern but also because of an increased level of relaxation resulting from the precise expectancy of the forthcoming movement [31].
Bands anticipating the forthcoming movement were appearing as far afield as Düsseldorf, West Germany, where "punk before punk" band NEU! formed in 1971, building on the Krautrock tradition of groups such as Can.
The evoked activity in these trials in which the square and triangle instructed forthcoming movement was then compared with that in the standard motor task in which the circle was the target cue instructing forthcoming movement.
It is defined as neuronal activity that starts once a forthcoming movement is instructed and continues until the movement is executed (Weinrich and Wise, 1982; Wise, 1985).
Thus, motor planning sometimes affects not only motor control but also sensory information processing which is related to the forthcoming movement.
Even the activity elicited by warning cues has been viewed in this light, as such cues have been informative of forthcoming movement, allowing the early preparation of action prior to an imperative cue (Williams et al., 2003, 2005).
Thus, as Pellizzer et al. (1993) also hypothesized, the two-thirds power law may express a limitation on the rate at which higher control commands can modulate the activity of neural pools collectively coding the direction of a forthcoming movement.
In the monkey, it was found that a forthcoming reaching movement is represented by set-related activity in the dorsal premotor cortex and primary motor cortex during an instructed-delay task.
