Brain Research Institute III (Theoretical Neurobiology)

The central aim of neuroscience is to understand how brains of animals and humans generate their rich repertoire of cognitive and behavioral capabilities. Our institute contributes to this goal by research on the computational processes and neuronal mechanisms underlying higher brain functions such as visual perception, attention, learning and memory.

The computational processes underlying such cognitive functions depend on numerous neurons widely distributed over various structures of the mammalian brain. They are thought to dynamically organize themselves into stimulus and task dependent groups to fulfill the permanently changing computational requirements posed by the surrounding world. Our aim is to understand the mechanisms which bind individual neurons into such functional groups and to understand the mechanisms and neuronal code used to process information within such groups. With respect to this topics we concentrate on parallel distributed mechanisms of information processing and in particular on temporal mechanisms such as neuronal synchronization and oscillation. Current research projects try to elucidate the role which these mechanisms fulfill in the context of visual perception, selective visual attention, and memory.

Major experimental techniques used in the lab are different types of multi-electrode recordings in behaving and anaesthetized animals (macaque monkey and rat). In addition, psychophysical methods, neuroanatomical techniques, MRI and electroencephalography are used. Theoretical work and data analysis is done in close cooperation with the Institute of Theoretical Neurophysics.

Support has been gained by the German Science Foundation (DFG, SFB 517), HFSP, the European Community and the VolkswagenStiftung.
