Neural Mechanisms Underlying Sensorimotor Synchronization With Different Forms Of Rhythms, Ryan Meidinger

UNO Student Research and Creative Activity Fair

Neural activity exhibits non-periodic rhythm [2] but it is unknown if neural activity synchronizes with non-periodic rhythms, as it does with periodic rhythms [1]. The purpose of this research is to determine the neural mechanisms present leading to synchronized finger tapping to varying rhythms. Twenty healthy young adults tapped their finger on a pressure sensitive pad, listened to metronomes, and wore a electroencephalogram (EEG) during synchronized finger tapping tasks (periodic, fractal, and random). Inter-tap intervals (ITIs), inter-beat intervals (IBIs), and frequency tags were used as the behavioral and cortical synchronization with the metronome. One-way ANOVAs were used to determine differences …
