Spatial visualization of temporal components for neuronal activity imaging

Posted on May 3, 2016 by P.T.R. Rupprecht

The standard analysis workflow for neuronal activity imaging based on calcium signals is to 1) draw ROIs around putative neurons, 2) extract the average fluorescence time trace of this ROI, 3) work with this timetrace for subsequent analysis (principal components, … Continue reading →

Undistort/unwarp images for resonant scanning microscopy

Posted on February 16, 2016 by P.T.R. Rupprecht

For image acquisition using a resonant scanning microscope, one of the image axes is scanned non-linearly, following the natural sinusoidal movements of the resonant scanner. This leads to a distortion of the acquired images, unless a online correction algorithm or … Continue reading →

PhD at the FMI

Posted on April 17, 2014 by P.T.R. Rupprecht

In April, I started my PhD in neuroscience in the Friedrich lab at the FMI. Topic will be the investigation of brain areas for higher olfactory processing in the zebrafish, and I’ll be working with different physiological methods.
