Modeling Dynamic Neural Activity by combining Naturalistic Video Stimuli and Stimulus-independent Latent Factors

no code implementations21 Oct 2024 Finn Schmidt, Polina Turishcheva, Suhas Shrinivasan, Fabian H. Sinz

We address this gap by proposing a probabilistic model that predicts the joint distribution of the neuronal responses from video stimuli and stimulus-independent latent factors.

Reproducibility of predictive networks for mouse visual cortex

no code implementations18 Jun 2024 Polina Turishcheva, Max Burg, Fabian H. Sinz, Alexander Ecker

Such weight vectors, which can be thought as embeddings of neuronal function, have been proposed to define functional cell types via unsupervised clustering.

The Dynamic Sensorium competition for predicting large-scale mouse visual cortex activity from videos

3 code implementations31 May 2023 Polina Turishcheva, Paul G. Fahey, Laura Hansel, Rachel Froebe, Kayla Ponder, Michaela Vystrčilová, Konstantin F. Willeke, Mohammad Bashiri, Eric Wang, Zhiwei Ding, Andreas S. Tolias, Fabian H. Sinz, Alexander S. Ecker

We hope this competition will continue to strengthen the accompanying Sensorium benchmarks collection as a standard tool to measure progress in large-scale neural system identification models of the entire mouse visual hierarchy and beyond.
