The spikefinder dataset

Recently, I mentioned a public competition for spike detection – spikefinder.codeneuro.org. I decided to spend a day two days and have a closer look at the datasets, especially the training datasets that provide both simultaneously recorded calcium and spike trains for single neurons. In … Continue reading

Reglo ICC serial port control via Matlab

For my experiments with zebrafish, I typically generate dynamic odor landscapes for the fish / fish brain explant by varying the speed of the wheels of an Ismatec peristaltic pump, thereby changing the concentration of the applied stimuli over time. Recently, I bought one of their digital … Continue reading

EODs for kHz imaging

J. Schneider et al., and S. Hell recently published a paper on STED microscopy, using EODs (electro-optical deflectors) to scan 512 x 512 pixels at frame rates of 1000 Hz. Compared to AODs, EODs offer the costumer-friendly advantage of not dispersing … Continue reading

A pockels cell with a broken crystal

In a 2P microscope, pockels cells are employed for fast control of the laser beam intensity. I use it for both switching off the laser beam during turnarounds of the resonant scanner, between two frames if they are not immediately one after … Continue reading

Finding the engram

In their Nature Reviews|Neuroscience article, Finding the engram, Sheena Josselyn, Stefan Köhler and Paul Frankland discuss the recent developments, mainly in circuit neuroscience in mice, that contributed to finding memories on the cellular level, the so-called engram. They accumulate the evidence from … Continue reading
