Simultaneous 2p imaging and visible-light optogenetics

We recently needed to verify how a large population of neurons reacts to weak optogenetic stimulation. We found that with a relatively straightforward setup, visible light optogenetic stimulation can be integrated into existing 2p rigs without resulting in problematic imaging … Continue reading

High quality time series plots

What is the best, or at least a good way to plot time-series data on a screen? When dealing with time series data in electrophysiology, a good deal of time is spent looking at plots in order to judge data … Continue reading

Open Ephys / Neuralynx comparison example traces

We just posted a direct comparison between the Open Ephys system and a Neuralynx Digital Lynx system on the Open Ephys blog. We ran a direct one-to-one comparison of the systems in the same mouse.  For now it’s example traces, … Continue reading

Digital fine wire tether

For recordings in freely behaving mice, it is important to minimize the weight and torque applied by the cables. This is especially important for experiments that require natural behavior and becomes a real issue for channel counts over 32 where even light … Continue reading

New headstages for open-ephys

Josh and I just assembled the first prototypes for the new and improved 32 channel headstages for the open-ephys system, an open source system for extra-cellular electrophysiology. These are smaller than the previous ones even though they now feature a standard omnetics … Continue reading
