Philipp Berens

Position: PhD Student  Unit: Alumni Bethge

I am interested in the computations performed by neuronal ensembles in the early visual system of primates . As a graduate student I am working with Matthias Bethge and Andreas Tolias developing statistical models and employing multi-cell recordings in awake primates.

 

CircStat, a Matlab toolbox for circular statistics including functions for descriptive statistics, hypothesis testing and correlation analysis (Link). The toolbox is described in detail my article, which can be found at JSS. The toolbox was selected as File Exchange Pick of the Week.

 

I am teaching the Introduction to Statistics class in the Masters program Cellular and Molecular Neuroscience together with Alex Ecker.
