Our article “Neural synchrony gives rise to amplitude- and duration-invariant encoding consistent with perception of natural communication stimuli” is now in press at Frontiers in Neuroscience Perception Science as part of the special issue/research topic “Understanding the Importance of temporal coupling of neural activities in information processing underlying action and perception”.
In this article we extend on our earlier findings that correlated (or synchronous) activity
of afferent receptor responses are used to encode high frequency communication signals that are embedded in an low frequency signal context – in a sense a figure/ground separation task in the frequency domain. The synchronous afferent activity is decoded by pyramidal neurons in the medulla which is further processed in higher order centers and leads to behavioral responses which we also recorded. While in previous studies we dissected the mechanism (eLIFE 2016; 5:e12993) and looked at how the contrast between stimulus and background (by varying the parameters of the background stimulus) effects coding and behavioral performance (eLIFE 2017; 6:e24482). This we now extended by exploring the effects of varying signal parameters (ampliutde and duration) onto encoding and behavior.
