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
