- <meta content="Objective: The present study was aimed at testing whether foreperiod duration affects the activity recorded over the primary sensorimotor
- cortices during the reaction time.
- Methods: The foreperiod duration (500 or 2500 ms) was varied across blocks of trials during a between-hand choice reaction time task;
- surface Laplacians were estimated from EEG recordings by the source derivation method.
- Results: Reaction time was shorter for the 500 ms foreperiod than for the 2500 ms foreperiod. A contralateral negativity/ipsilateral
- positivity pattern showed up over the primary sensorimotor cortices. The time between the contralateral negativity onset and the
- electromyographic onset was shorter for the 500 ms foreperiod than for the 2500 ms foreperiod, which suggests that the foreperiod affects
- the implementation of the motor command. Furthermore, the interval between the onset of the voluntary electromyographic activity and the
- mechanical response was shorter for the 500 ms foreperiod than for the 2500 ms foreperiod.
- Conclusions: These results indicate that time preparation affects both central and peripheral motor processes.

- cortices during the reaction time.
- Methods: The foreperiod duration (500 or 2500 ms) was varied across blocks of trials during a between-hand choice reaction time task;
- surface Laplacians were estimated from EEG recordings by the source derivation method.
- Results: Reaction time was shorter for the 500 ms foreperiod than for the 2500 ms foreperiod. A contralateral negativity/ipsilateral
- positivity pattern showed up over the primary sensorimotor cortices. The time between the contralateral negativity onset and the
- electromyographic onset was shorter for the 500 ms foreperiod than for the 2500 ms foreperiod, which suggests that the foreperiod affects
- the implementation of the motor command. Furthermore, the interval between the onset of the voluntary electromyographic activity and the
- mechanical response was shorter for the 500 ms foreperiod than for the 2500 ms foreperiod.
- Conclusions: These results indicate that time preparation affects both central and peripheral motor processes.
