Abstract

To interact with our environment, we constantly use temporal information. Human and non-human animals are able to estimate time intervals at different time scales. The scale from a few hundred milliseconds to seconds is especially critical for sensory and motor processing, learning, and other cognitive functions. However, there is still no consensus on the underlying neural mechanisms of such ability. The present project intends to investigate neural correlates through the multivariate analysis of electroencephalographic (EEG) signal patterns in different temporal tasks, in order to determine if different tasks and temporal contexts influence a neural representation of time. Different tasks involving temporal estimates and expectations will be performed by human’s participants, together with concomitant EEG recordings. The results obtained with the project will provide a better understanding of the neural bases of temporal processing (AU)
