WebThe characteristic reaction time constant tK = 200 ms at 25 °C and CBo = 2.5 mM, while rR = 65 ms at 35 °C and CB0 = 4.7 mM, which can be used to bound the micromixing times, rM, no greater than them, respectively. The four examples below illustrate how the characteristic reaction time is determined. WebReaction time can be fractionated into components of premotor time (the time between stimulus onset and a change in muscle electrical signal) and motor time (the time between change in muscle signal and onset of limb displacement). Total reaction time is the linear sum of premotor time and motor time.
