Abstract:
Objective To achieve millisecond grade precision in the design model of event-related fMRI experiment.Methods The impact factors of time precision were analyzed,and solutions were put forward.Results The parameter of E-Prime(a software dedicated to psychology study) was adjusted to get millisecond precision.Conclusion General computer is very difficult to achieve millisecond grade due to software and hardware factors,but it can be achieved through adjusting the parameter of E-Prime.
