Title: Active sensing and Brain Oscillations

 

Abstract: 

Human communication relies on quasi-rhythmic signals such as speech and face movements. In addition, the visual system also samples the environment in a quasi-rhythmic way. I will show examples of rhythmicity in sensory sampling and discuss how this relates to brain oscillations. Specifically, brain oscillations seems to match the dominant spectral structure of relevant sensory stimuli. This is potentially relevant because low-frequency brain oscillations represent changes in excitability of neural populations. I will demonstrate that phase resetting is a potentially powerful mechanism for coding of sensory information and for aligning temporal windows of high neural excitability to salient events in sensory stimuli.
