Facilitating the sharing of electrophysiology data analysis results through in-depth provenance capture

1 code implementation16 Nov 2023 Cristiano André Köhler, Danylo Ulianych, Sonja Grün, Stefan Decker, Michael Denker

We present Alpaca (Automated Lightweight Provenance Capture), a tool that captures fine-grained provenance information with minimal user intervention when running data analysis pipelines implemented in Python scripts.

Evaluating the statistical similarity of neural network activity and connectivity via eigenvector angles

no code implementations8 Sep 2022 Robin Gutzen, Sonja Grün, Michael Denker

In this study, we construct a statistical test for the comparison of matrices representing pairwise aspects of neural networks, in particular, the correlation between spiking activity and connectivity.

LFP beta amplitude is predictive of mesoscopic spatio-temporal phase patterns

1 code implementation28 Mar 2017 Michael Denker, Lyuba Zehl, Bjørg E. Kilavik, Markus Diesmann, Thomas Brochier, Alexa Riehle, Sonja Grün

Beta oscillations observed in motor cortical local field potentials (LFPs) recorded on separate electrodes of a multi-electrode array have been shown to exhibit non-zero phase shifts that organize into a planar wave propagation.
