Paper on TRN induced modulation of arousal state
Our paper ‘Thalamic reticular nucleus induces fast and local modulation of arousal state’ just went online at eLife. In this study we found that optogenetic drive of TRN induces slow waves in associated regions of neocortex, similar to the local … Continue reading

Exporting figures from Matlab into Illustrator
Getting nice figures out of matlab is always a bit of a nightmare. Here’s a few pretty simple steps I’ve adopted that work ok for my needs. I use subplots quite a lot, and try to get my figures as … Continue reading

Maintaining local pixel cross-correlation in image registration
This post is about the effect of re-sampling in image registration methods on local pixel cross correlation for analyzing calcium imaging data. In awake 2p imaging, animal motion causes brain tissue motion and image motion. While z-motion that can not be recovered … Continue reading

Opinion piece on open-source electrophysiology
Josh and I (of Open Ephys), Greg Hale (of Arte) and Jon Newman (of Neurorighter, Cyclops & Puggle) just published an opinion piece on the role of open-source approaches and interfaces for large-scale electrophysiology. Its a bit of a review of … Continue reading

Recording simultaneous units in cortex with the flexDrive
We’ve been using the flexDrive (wiki) for over a year now, recording almost 100 sessions in 5 mice. I’m just now starting to analyze neural ensemble statistics that require simultaneously recorded neurons. Here’s the real-world distribution of how many simultaneous neurons … Continue reading

Programming in science – software as a manual tool
Just stumbled upon this great post by John D. Cook that explains very well why most of the software we write for scientific data analysis are poorly constructed and almost never properly tested or documented: Scientists see their software as a kind of … Continue reading
