Since the beginning of this year, I’ve been working on developing software to perform spike sorting on extracellular recordings from our group and a number of other labs at Flinders. For the past five weeks I’ve had assistance from our Medical Advanced Studies student, Alex Oo, who has been located in our lab and trying out various ideas for spike representation and clustering.
Alex has also been playing with the use of Jupyter Notebooks. They offer a way to run and modify Python code interactively and view the results, including generating figures and other visualisations. Here is a screen cap from a notebook that Alex has been working on, showing three clusters of spikes, with their spike trains and average waveforms.
Alex will still be with us intermittently until July, and has also been exploring ways to visualise the way that the shape of the spike for a particular unit changes over time, so watch this space!
