Title:
Statistical methods for assessing temporal structure in the activity 
of the nervous system
<br>
<br>

Abstract:
One of the familiar controversies in neuroscience is the rate vs 
temporal coding controvery concerning how spike trains encode 
information: particularly, whether all that matters are the spike counts 
(or rate of spiking) in coarse time intervals, or whether the detailed 
positions of the spikes conveys information. I will discuss some 
statistical issues this controversy raises and techniques we have 
developed to address them, in particular focusing on the 
assessment of significance of synchronous discharges among 
simultaneously-recorded neurons, with experimental applications.
