The new Bernstein research group "Functional adaptation of the visual
cortex" funded by the BMBF has been established at the Center for Cognitive
Sciences/University of Bremen. This interdisciplinary research group works
on selected topics in Computational Neuroscience, joining theory and
experiment to understand information processing in the brain. The following
institutes participate in the Bernstein group: 

Institute for Theoretical Neurophysics 	
Brain Research Institute III (Theoretical Neurobiology)	
Brain Research Institute IV (Human Neurobiology) 	

The aim of this Bernstein Group is to investigate neuronal mechanisms
underlying functional adaptations in the visual system by theoretical and
experimental approaches. The research program will comprise four projects,
investigating (1) theoretical concepts encompassing putative neuronal
mechanisms and structures enabling adaptive, selective information
processing in the cortex (Prof. Dr. Pawelzik), (2) adaptive mechanisms
integrating contextual information, prior knowledge, and on-going cortical
activity into coherent percepts (NN), (3) adaptive, task- and
stimulus-specific routing of information flow in visual cortex (Prof. Dr.
Kreiter), and (4) dynamic integration of temporal signals, and fast control
and adaptive learning under closed loop conditions (Prof. Dr. Fahle). 
Our integrative approach encompasses theoretical investigations and
modelling studies on different levels, tightly linked to experimental
investigations combining psychophysical experiments with
electrophysiological recordings of attentional modulation and inter-areal
communication in awake and behaving monkeys, and complemented by
psychophysical and fMRI experiments in humans. 

Positions are offered for:

Project 1: Mechanisms and structures of adaptive neural information
processing
1 PhD student (E13/2 TVöD) will primarily use theoretical approaches to
investigate mechanisms of adaptive computation in spiking neuronal networks.
The candidate should have a strong background in neural network theory, and
be also interested in testing newly developed paradigms in biophysically
realistic settings with large-scale computer simulations running on our
Linux cluster.

Project 2: Adaptive integration of contextual information and prior
knowledge into coherent percepts
1 Post-Doc (E 14 TVöD) will lead and shape the research activities in this
project. In parallel, this experienced candidate is expected to coordinate
the exchange between experimental studies and theoretical work within the
whole research group, hereby structuring the collaboration between the
different projects, as well as organizing the exchange of ideas with
external partners at the Bernstein centers.
1 PhD student (E13/2 TVöD) will perform psychophysical experiments (in Prof.
Fahle's Lab) on feature integration in visual cortex, guided by theoretical
work of the Post-Doc.

Project 3: Adaptive routing of information flow in the visual cortex
1 PhD student (E13/2 TVöD) will investigate attention-dependent signal
selection and dynamic routing of information in the visual cortex by
electrophysiological multi-electrode recordings in trained monkeys.
1 PhD student (E13/2 TVöD) with a comprehensive background in theory and
data analysis will identify basic neuronal mechanisms of signal selection
and dynamic routing of information. The candidate is expected to study
realistic models of cortical microcircuits based on constraints from monkey
experiments and psychophysical studies performed within the Bernstein group.

Project 4: Dynamic integration of temporal signals and adaptive learning
1 PhD student (E13/2 TVöD) with a background in psychophysics will
investigate temporal factors in figure-ground segregation, object
representation and closed loop eye-hand coordination with psychophysical
methods in humans.
1 PhD student (E13/2 TVöD) will study multi-modal adaptation on different
time scales with spiking neuronal network models. The candidate should be
interested in identifying putative mechanisms of fast adaptation and
learning, and in establishing cross-links between experimental work,
learning theory, up to control problems in technical applications.

Ideal candidates would be interested in pursuing research with a strong
emphasis on computational questions and their experimental investigation in
a tight interdisciplinary network. We also expect and encourage candidates
to contribute own ideas in shaping the project. Basis for application is a
successful graduation at a university in the field of natural studies.
The University of Bremen desires to increase the number of women in research
and thus explicitly solicits applications from qualified women. Handicapped
applicants will be treated preferentially if their personal and professional
qualifications are equivalent. For additional information, contact
positions at bernstein.uni-bremen.de or see http://www.bernstein.uni-bremen.de.


The project will start from April 2007 onwards.
