Open Source Brain (http://www.opensourcebrain.org) was created as a platform for sharing and collaboratively developing models in computational neuroscience. Models of cells and circuits in standardized formats can be visualized, analyzed and simulated through a standard web browser. The aim has been to improve the quality, accessibility and scientific rigor of models used to investigate brain function.

Following a renewal of their funding from the Wellcome Trust, OSB are expanding the functionality of the platform to also enable sharing of the experimental data behind the models. The 2019 OSB Workshop will highlight the latest features of OSB and engage current and future users of the platform through invited talks, hands on demonstrations, and user presentations.

The two key themes of the meeting will be:

1) Accessible sharing of cellular neuroscience data

Through support for the Neurodata Without Borders (NWB) format, OSB will facilitate sharing of multiple types of experimental data used to constrain computational models, including electrophysiological recordings, Ca²⁺ fluorescence imaging, 2D, 3D and 4D imaging and behavioural data.

2) Modeling the cortex across scales

Cortical networks are modeled at many scales from abstract representations of interacting populations (neural masses) to networks of biophysically and morphologically detailed cell models. NeuroML is being expanded to cover a greater range of these models, which will allow them to be shared and simulated on OSB, facilitating comparison of models and ideas between researchers. This ongoing work is taking place as part of the SIG on Standardised Representations of Network Structures.
