Microcontroller Audiostimulation for Brain FMRI Examinations
MetadataShow full item record
During fMRI acquisition of task related data the variability of time lag between the audio stimulus demand and its actual playback causes a huge problem for precise data analysis. The lag is probably arised because of using standard PC for whole stimulation management, where is not possible to achieve absolute control of stimuli timing. The developed device for audio stimulation based on Arduino Due microcontroller solves that problem. The control of the audio stimuli playback is realized by external trigger. All together allows to avoid variable and high lag of audio stimulation.
