Review: Epoxy
This is the first part of a series in which I will review various glues etc. This is a fairly shallow and boring topic, but systems neuroscience is a field in which we often have to build things and and … Continue reading

Use teensy microcontrollers instead of arduinos
This post is mostly just an advertisement for the teensy family of microcontrollers (MCUs). People like to use ‘arduino’ as shorthand for easy to use MCU (and wherever you go you see arduinos with ratsnets of loose wires stuck in … Continue reading

Low cost laser cut syringe pump
Here’s a yet another design for a cheapish open source syringe pump. There are many designs for these out there already, including 3d printed ones, and ones made from lego. This one is designed to be fast to build, robust, … Continue reading

Backlight for highspeed video whisker tracking
Here’s a simple recipe for a very bright uniform background for highspeed videography. This approach will work well for any applications where the outline of a small objects needs to be measured at high frame rates. For vibrissa tracking, or … 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 realworld distribution of how many simultaneous neurons … Continue reading

Template matching in manual spike sorting
When sorting spikes, it is pretty common to find a bunch of nice example waveforms for a unit, but it is often tricky to find good features that cleanly separate these waveforms from the rest. For this reason, many clustering packages can … Continue reading

Simpleclust – manual spike sorting in matlab
In my work, I often need to maximize the number of identified neurons I can record from simultaneously, so I do all my spike sorting manually. While there are a bunch of good free options, none quite fit my workflow, … Continue reading
