Real-time tracking and 2p imaging with sub-ms timing

In this work, the authors used fast optical motion tracking and 2p imaging to measure the activity of individual neurons in freely moving animals. No surgery. No optical window. No restraint. And all the benefits of multiphoton imaging. The project was undertaken by Marc Gershow and his lab, principally co-first authors Doycho Karagyozov and Mirna

Large scale, open neuroscience is a work-in-progress

The International Brain Lab (IBL) project has an outstanding team of PIs, covering both theory and experiments. The measurements themselves are interesting, and can lead to important insights. However, what is most distinctive is the organization of the project. The experimental labs will all train mice to perform the same task, and each lab will

Server space – cloud or on-campus?

Cloud storage is not the cure-all it is sometimes proposed to be. On-campus servers have some advantages in transmission speed and cost, especially as storage requirements grow considerably. Talk to your campus IT services before shelling out 90% of your R01 to Amazon to store your petabyte (PB) dataset. Cloud storage is good for personal

Bias – Good people aren’t good enough

This is a bit off topic, but it’s my blog, so I’ll allow it. A brief note on bias: It’s not good enough to be a good person. Bias can be like an optical illusion. It’s something your brain does despite your best intentions. You have to actively address your biases. Don’t trust yourself to

New online forum for Labrigger

Here are the new Labrigger forums, running on Discourse. Background: Justin Kiggins asked about having a Slack channel for Labrigger. The poll indicated majority support, so we agreed to set it up. Alexander Chamessian suggested using Discourse instead of Slack, we investigated and found it was cheaper and had better organization for this type of

Using NI DAQmx in MATLAB

This post is from Rob Campbell: As part of TENSS [editor’s note: this course is run by great people– highly recommended] we have created a set of examples showing how to use DAQmx in MATLAB without the Data Acquisition Toolbox. This is achieved using Vidrio’s free wrapper, which exposes almost all of the DAQmx API

OpenMV – Fast and easy machine vision

OpenMV is an open source machine vision system. It’s designed to be easy-to-use, with a gentle learning curve. They want this to be the “Arduino of Machine Vision”. The software IDE is free and open. The hardware is available from Sparkfun and other places. Color blob detection, eye and pupil tracking, motion detection, etc. You

Moire lenses

Moiré lenses are cool: two patterned diffractive optical elements are rotated relative to each other to vary the power of the “lens”. Just watch the video (below).
