Correlation of EEG Brain Waves in a Time Perception Task

The perception of time is a fundamental part of our daily life. Several studies have reported that time estimation involves the communication and synchronization of neural assemblies that decode the duration of time. Therefore, the purpose of the present study is to evaluate the interaction between different brain areas during time estimation. Brain electrical activity was recorded during a time perception task and correlation matrices were calculated using different frequency bands. Graph networks show an important contribution of fronto-central regions and left hemisphere. The estimation of time could involve the recruitment of attentional resources and the inhibition of motor responses to make a temporal prediction, by this way possibly monitoring the "flow of time".
