Helene Schreyer is currently a post-doctoral researcher with Tim Gollisch at the University Medical Center Göttingen, Germany. She studied Psychology and did her master thesis with Pascal Fries at the Ernst Strüngmann Institute (ESI) for Neuroscience in Frankfurt on attentional modulation of brain rhythms in the visual cortex. During her master thesis, she became interested in earlier visual areas and started her PhD in the lab of Tim Gollisch to work on the retina. In the retina, she combines multielectrode array recordings from ganglion cells with single cell recordings from bipolar cells. Her work focuses on nonlinear properties of bipolar cells and signal transmission from bipolar to ganglion cells under artificial and natural light stimulation.
