We validate the model, use it to explain the experimental results, and calculate constraints for the parameters of the model using the experimental data. The formulation of an accurate model at a proper abstraction level and its application to real experimental data requires several important prerequisites; the experimental data has to be pre-processed adequately, it has to be cleaned of artefacts which could impact the results, and the provenance of the pre-processing and the applied analysis methods as well as the metadata of the recording has to be readily available and searchable to be taken into account in the formulation of the model. To this end, we first explore artefacts in electrophysiological data which could impact our results. We group them into multiple artefact types, propose removal methods for all types, and evaluate the removal methods to check their performance. We then build upon a pre-processing workflow for electrophysiological data which incorporates the artefact removal methods which have proven to be successful in the previous step by improving, expanding, and generalising the workflow. Data pre-processing and artefact removal is a growing demand in computational neuroscience as experiments become more and more complex and more data of different modalities can be recorded simultaneously. We propose a common framework for data handling in electrophysiology, design a checklist for designing a rigorous acquisition and pre-processing workflow, and apply it to an example use-case. In the final step, we formulate a spatial model of the embedding of synfire chains in a cortical network and apply it to spatio-temporal spike patterns detected in macaque primary motor cortex during a delayed reach-to-grasp task. First, we validate that synfire chain activity can be detected as spatio-temporal spike patterns in this experimental setup despite the massive sub-sampling of the underlying neuronal populations. Building upon this, we fit the model to the experimental results, show that synfire chains can explain the observed spike pattern statistics, and calculate constraints of the model parameters given the experimental results: the groups of the synfire chains have to contain many neurons and have to be broadly distributed in space.}, cin = {163110 / 160000}, ddc = {570}, cid = {$I:(DE-82)163110_20180110$ / $I:(DE-82)160000_20140620$}, pnm = {HBP SGA3 - Human Brain Project Specific Grant Agreement 3 (945539) / HMC - Helmholz Metadata Collaboration $(HMC_20200306)$}, pid = {G:(EU-Grant)945539 / $G:(DE-HGF)HMC_20200306$}, typ = {PUB:(DE-HGF)11}, doi = {10.18154/RWTH-2024-09140}, url = {https://publications.rwth-aachen.de/record/994159}, }
