Analysis methods for massively parallel neuronal data

Analysis methods for massively parallel neuronal dataCopyright: Emiliano Torre et al. 2016 Plos CB Figure 1

Temporally, precise correlations between simultaneously recorded neurons have been interpreted as signatures of cell assemblies, i.e., groups of neurons that form processing units. Evidence for this hypothesis was found on the level of pairwise correlations in simultaneous recordings of few neurons (e.g. Riehle et al, 1997; Kilavik et al, 2008). Increasing the number of simultaneously recorded neurons increases the chances to detect cell assembly activity due to the larger sample size. Recent technological advances have enabled the recording of 100 or more neurons in parallel. However, these massively parallel spike train data require novel statistical tools to overcome considerable combinatorial and multiple testing issues. Over the last decade we have developed such methods. First approaches were based on population or pairwise measures of synchronization, and later led to methods for the detection of various types of higher-order synchronization and also of spatio-temporal patterns. The latest techniques combine data mining with the assessment of statistical significance.
