### OSB Workshop 2014: Building and sharing models of the cortex

This page has been moved to: http://opensourcebrain.org/docs/Help/Meetings#OSB_2014. meeting was the second main meeting of the Open Source Brain initiative (http://www.opensourcebrain.org).

Dates: **9am Wednesday 14th - 5pm Friday 16th May, 2014**

Location: [Hotel Calabona](http://www.hotelcalabona.com/), [Alghero](http://www.alghero-turismo.it/en/), Sardinia

Local organisers: [Sergio Solinas](/users/23), Irene Solinas

Organising committee: [Padraig Gleeson](/users/4), [Eugenio Piasini](/users/3), [Angus Silver](/users/6), [Boris Marin](/users/67)

### Focus of the meeting

There are an increasing number of cortical cell and network models being developed and made publicly available, from networks of leaky integrate and fire neurons based on cortical connectivity and firing properties, to multicompartmental, conductance based cell models. Many of these are being reused, reimplemented and extended to address new scientific questions by labs around the world.

In this meeting, we looked at the range cortico-thalamic models out there which are of widespread interest and discussed the best ways to get these into public, open source repositories, in standardised formats such as NeuroML and PyNN. We investigated the steps needed to ensure these models are well tested, annotated and ready for use as research tools by the attendees and the wider community.

There were presentations from experimentalists who are producing the data to constrain these models, as well as simulator and application developers who are creating the infrastructure to build, simulate, analyse and share the models.
