Left-handed individuals show a 4 ms later Wave Pb in the 45-60 ms latency range of the auditory middle latency response (MLR) than right-handed individuals. Examination of auditory evoked potentials in fifteen right-handed and fifteen left-handed normal hearing adults showed that this difference was not evident in time periods earlier or later than 45-60 ms. The isolation of this latency difference to a specific time period suggests that the source or sources of Wave Pb may be an independent physiological index which correlates with hand preference.
与右利手个体相比，左利手个体在听觉中潜伏期反应（MLR）45 - 60毫秒潜伏期范围内的波Pb出现时间晚4毫秒。对15名右利手和15名左利手听力正常的成年人的听觉诱发电位检查表明，在早于或晚于45 - 60毫秒的时间段内，这种差异并不明显。将这种潜伏期差异分离到特定时间段表明，波Pb的一个或多个来源可能是与利手偏好相关的独立生理指标。
