Project description:
Our research focuses on visual information processing in primary visual cortical areas using various animal models. We investigate how manifold parameters given in a visual scene are represented across neuronal populations using voltage-sensitive dye imaging (VSDI).

VSDI, a new optical recording method, marks a significant step forward in the continuing scientific effort to decipher the brain’s neural code and computational strategies – the mapping of the functions of the various nerve cells in the brain and the interactions between them.

Given the tremendous density of intra-cortical connections neural interactions play a major role in computing behavioural relevant information. We aim to identify the streams of bottom-up and top-down information processing leading to perceptual correlates.

Real-time optical imaging using voltage-sensitive dyes

The applied fluorescent dyes stick to the outer membranes of living brain cells and glow with varying degrees of brightness according to the level of synaptic activities. Thus our method provides an ideal access to questions dealing with highly dynamic activity patterns across selected cortical areas.

For PhD-positions, interest and strong background in Computational Neuroscience, Physics, and Mathematics are required.
