Journal ArticleDOI
Perineuronal nets stabilize the grid cell network
Ane Charlotte Christensen,Kristian Kinden Lensjø,Mikkel Elle Lepperød,Svenn-Arne Dragly,Hallvard Sutterud,Jan Sigurd Blackstad,Marianne Fyhn,Torkel Hafting +7 more
TL;DR: It is shown that removal of perineuronal nets leads to lower inhibitory spiking activity, and reduces grid cells’ ability to create stable representations of a novel environment, and that PNN removal in entorhinal cortex distorted spatial representations in downstream hippocampal neurons.
Journal ArticleDOI
Open source modules for tracking animal behavior and closed-loop stimulation based on Open Ephys and Bonsai.
Alessio Paolo Buccino,Mikkel Elle Lepperød,Svenn-Arne Dragly,Philipp Hafliger,Marianne Fyhn,Torkel Hafting +5 more
TL;DR: An open source, low-cost, adaptable, and easy to set-up system for combined behavioral tracking, electrophysiology, and closed-loop stimulation that robustly visualizes real-time tracking and reliably recovers tracking information recorded from a range of sampling frequencies
Journal ArticleDOI
Experimental Directory Structure (Exdir): An Alternative to HDF5 Without Introducing a New File Format.
Svenn-Arne Dragly,Milad Hobbi Mobarhan,Mikkel Elle Lepperød,Simen Tennøe,Marianne Fyhn,Torkel Hafting,Anders Malthe-Sørenssen +6 more
TL;DR: This work proposes a novel alternative to Hierarchical Data Format 5, the Experimental Directory Structure (Exdir), an open specification for data storage in experimental pipelines which amends drawbacks associated with HDF5 while retaining its advantages.

Experimental Directory Structure (Exdir): An alternative to HDF5 without introducing a new file format
Svenn-Arne Dragly,Milad Hobbi Mobarhan,Mikkel Elle Lepperød,Simen Tennøe,Torkel Hafting,Marianne Fyhn,Anders Malthe-Sørenssen +6 more
TL;DR: The Experimental Directory Structure (Exdir) is a proposal to standardize a storage solution that has become an increasingly popular alternative to Hierarchical Data Format 5, namely to use directories to define a hierarchy, store data in binary files, and metadata in text files.
Journal ArticleDOI
Neuronify: An Educational Simulator for Neural Circuits.
Svenn-Arne Dragly,Milad Hobbi Mobarhan,Andreas Våvang Solbrå,Simen Tennøe,Anders Hafreager,Anders Malthe-Sørenssen,Marianne Fyhn,Torkel Hafting,Gaute T. Einevoll,Gaute T. Einevoll +9 more
TL;DR: An educational app, Neuronify, allowing the user to easily create and explore neural networks in a plug-and-play simulation environment, and allowing students with no programming experience to create and simulate neural networks.
