Publication: Inhibition of motor-related activation during a simple reaction time task requiring visuomotor mental rotation

PDF  Seminal work by Georgopoulos and colleagues (1987) showed that reaction time (RT) increased when a rotational mental transformation had to be calculated prior to responding. A loud acoustic stimulus can be used to trigger prepared responses, so this effect was used in the current experiment to determine how preparatory activation levels in…

Publication: Using TMS to reveal cortical excitability during preparation for a RT task.

PDF  This study investigated the entirety of the timecourse of cortico-spinal excitability changes during a reaction time task – from the time in between trials, and throughout the foreperiod and response interval. The results show a pattern of increase in excitability that occurs just after the “get ready” signal which…
