Topic: Subthreshold activity

A change in pairwise spike train correlations is a well-established neural correlate of a shift in brain state, and as such has been the topic of intense study. However, while the explosion in population recording has provided a wealth of data to measure spike train correlations and their state dependence, there continues to be ambiguity in the biological mechanisms that mediate changes in correlated activity. One reason for this lack of understanding is the vast set of possible circuit and cellular realities that can support correlated spiking activity. To provide insight into how circuit and
