The analysis of extracellular recordings is a computationally and conceptually complex task with multiple sources of error and bias that can affect subsequent data interpretation. The advent of high-density extracellular micro-electrode arrays (MEAs) now allows recording from hundreds to thousands of channels that poses significant challenges. Additionally, current analysis workflows lack standardisation, and few attempts have been made to make perform systematic comparisons between different solutions and approaches.
This workshop will bring together electrophysiologists and developers of tools for the analysis of extracellular recordings, with the following goals:
The meeting will consist of a series of invited talks and discussion sessions on the topics of spike sorting and reproducible data analysis. We hope to not only summarise the state of the art, but to also develop recommendations for new solutions. We invite poster presentations to be held on 24. June.

By train the nearest station is Edinburgh Waverley, which is less than a 15 minute walk from the Informatics Forum.
See National Rail Enquiries for train information.
For those coming from further afield, information about travel to and from Edinburgh Airport is available. A taxi to the city centre from the airport costs about 22GBP to 24GBP one way. There is an express bus from the airport called Airlink that terminates in the city centre (7.50GBP return), and a tram travelling the same route (8.50GBP return, get off at Princess street). Journey time is about 30 minutes.
