Physiology and Modelling of the Visual System

This project concerns electrophysiology as well as modelling.
Electrophysiology: Here we have recorded cells from the visual cortex and the thalamus (LGN) focusing on several questions:
The action of intracortical inhibition on direction and orientation selectivity of cortical cells (1987-1990)
The influence of cortico-thalamic projections on the cell responses in the LGN (1990-2000)
The influence of the state of arousal on the cell behaviour in the LGN (1995-2000) and the cortex (1998-2000)
The effect of stochastic resonance on visual cortical responses (2004-ongoing)
Modelling: Here we are mainly concerned with large biophysical models of different part of the visual system:
Models of the visual cortex (1990-1995)
Models of the interactions between visual cortex and thalamus, mostly focusing on receptive field changes due to cortico-thalamic influences and/or influences of the state of arousal or attentiveness, respectively (1995-2000)
Detailed model of the Retina (2002-ongoing)

Main cooperation partners:
- Matthias Hennig (Edinburgh, Scotland, models of the retina).
- Klaus Funke (Bochum, Physiology)
