The Center for Cognitive Sciences of the University of Bremen invites
applications for open Post-doc and Ph.D. student positions for three
related projects:
1.) 'Interareal phase coherence as a mechanism for attention-dependent
neuronal signal routing: A model-guided causal analysis using new,
multi-contact floating silicon probes for intracortical chronic
stimulation and recording in primates' (http://www.isee.uni-bremen.de

The Center aims at understanding neural information processing at the
systems level using an interdisciplinary approach including experimental
investigations in animals and humans in close combination with
theoretical approaches. Taking advantage of the results of its basic
research the center develops new approaches and applications in the
field of neuro-technology and brain-computer interfaces. Its members
come from the fields of neurobiology, theoretical neuroscience,
neurology, ophthalmology, electrical engineering, microsystems
technology, computer science, and philosophy.
Interested candidates should send their application in German or English
language, including the reference number of the position, a letter of
motivation, CV, copies of school and university certificates
(master/diploma or equivalent) until the 10th of September to:
Agnes Janßen
Cognium
Hochschulring 18
Universität Bremen
D-28359 Bremen
Germany
Severely disabled applicants and women with essentially identical
technical and personal suitability will be preferentially selected.
The open positions:
1 Post-doc Position - Code: InAuKa-Kreiter
(Project: InAuKa - Electrophysiology in the group of Andreas Kreiter)
At the Center for Cognitive Sciences, Institute of Brain Research, a
post-doc position is available in a DFG-funded project of the priority
program "Resolving and Manipulating Neuronal Networks in the Mammalian
Brain - from Correlative to Causal Analysis" (DFG SPP 1665).
The projects objective is to investigate the causal role of synchronized
gamma-band activity between different cortical areas for
attention-dependent transmission of neuronal signals through cortical
networks. Within the course of these electrophysiological experiments
with macaque monkeys using advanced multi-electrode recording
techniques, methods to selectively influence parts of the involved
networks during attentive processing of visual stimuli by electrical
stimulation will be established. The networks dynamic properties will be
characterized and newly developed multi-contact microelectrodes be
tested. The project will be performed in close co-operation with our
partners in engineering science and theoretical neurosciences.
Candidates should have a strong background in electrophysiology, a good
understanding of theoretical concepts and advanced data analysis and the
ability to communicate effectively in an interdisciplinary project team
with theoreticians and engineers. Programming skills are of advantage.
The position is available for a period of 3 years. Interested
researchers are strongly encouraged to contact Prof. Kreiter
(kreiter@brain.uni-bremen.de) to receive detailed information.
1 PhD Position - Code: InAuKa-Ernst
(Project: InAuKa - Theoretical neuroscience in the group of Udo Ernst)
One PhD student with background in physics or computational neuroscience
is required for performing network simulations and formal analysis of
information gating mechanisms. She/he will focus on oscillatory network
activity and apply phase-response theory to determine how information
gating is influenced by an external visual or electrical stimulus. To
support the modeling studies, the student shall perform advanced data
analysis and assist the group of Prof. Kreiter in establishing a
closed-loop stimulation setup. The student will be supervised by Udo
Ernst and is expected to closely collaborate with the group of Prof.
Kreiter to link model simulations to the data gathered in the
experiments. Basic knowledge in programming and in formal
methods/Computational Neuroscience are required.
1 PhD Position - Code: Isee-Kreiter
(Project: I-See - Electrophysiology in the group of Andreas Kreiter)
At the Center for Cognitive Sciences, Institute of Brain Research, a PhD
position is available in the University of Bremen's Creative Unit "I-See".
The key objective of this research project is developing the basis for a
cortical visual prosthesis. The PhD-student will perform
electrophysiological experiments with multi-electrode arrays placed on
primary visual cortex of macaque monkeys. The perception of phosphenes
induced by electrical stimulation, the influence of electrical
stimulation on neuronal activity in V1 and the interaction of visual and
electrical stimulation will be investigated. The project will be
performed in close co-operation with our partners in engineering science
and theoretical neuroscience.
The candidate should have a profound interest in neuroscience and its
methodological and applied aspects and a strong background in
neurophysiology. Programming skills are of advantage. The position is
available immediately for a period of 3 years. Interested students are
strongly encouraged to contact Prof. Kreiter
(kreiter@brain.uni-bremen.de) to receive detailed information.
1 PhD Position - Code: Isee-Pawelzik
(Project: I-See - Theoretical neuroscience in the group of Klaus Pawelzik)
We are looking for a PhD student with a background in physics and/or
computational neuroscience. She/he will work in close cooperation with
experimentalists in the group of Andreas Kreiter. The student will
analyse electro-physiological data with the goal to identify the
underlying network structure/model which generates a specific neural
response and visual percept to a particular electrical stimulation.
She/he will then invert this model in order to determine the
spatio-temporal stimulation pattern required for creating a desired
visual percept. Basic knowledge in programming and in formal
methods/Computational Neuroscience are required.
1 PhD Position - Code: Bernstein-Ernst
(Project: Berstein Award Udo Ernst - Electrophysiology)
Goal of this study is to investigate neural signatures and mechanisms of
parallel functional configuration in multiple visual areas with
massively parallel multielectrode recordings. The PhD student will
conduct experiments on awake behaving macaque monkeys in collaboration
with the group of Prof. Dr. Andreas Kreiter
(kreiter@brain.uni-bremen.de), and analyze the collected data. This
includes familiarization and training of the monkeys, preparation of the
experimental setup and recordings, implantation of the electrode arrays,
and recording of the data under different visual perception tasks.
He/she should be familiar with standard methods of data analysis, as
well as with elementary concepts from machine learning and information
theory. He or she should have a degree (master/diploma or equivalent) in
natural sciences (e.g. Biology) with focus on experimental work
(preferably Animal Physiology). Basic programming skills and interest in
formal methods from Computational Neuroscience are required. We expect a
high motivation for communicating and collaborating with the other
subprojects in the group.
