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:<br>
<br>
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'

<br>
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. <br>

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:<br>

Severely disabled applicants and women with essentially identical
technical and personal suitability will be preferentially selected.<br>
<br>
The open positions:<br>
<br>
1 Post-doc Position - Code: InAuKa-Kreiter<br>
(Project: InAuKa - Electrophysiology in the group of Andreas
Kreiter)<br>
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).<br>
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.<br>
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 (<a class="moz-txt-link-abbreviated" href="mailto:kreiter@brain.uni-bremen.de">kreiter@brain.uni-bremen.de</a>) to receive
detailed information.<br>
<br>
1 PhD Position - Code: InAuKa-Ernst<br>
(Project: InAuKa - Theoretical neuroscience in the group of Udo
Ernst)<br>
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.<br>
<br>
1 PhD Position - Code: Isee-Kreiter<br>
(Project: I-See - Electrophysiology in the group of Andreas Kreiter)<br>
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”. <br>
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.<br>
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
(<a class="moz-txt-link-abbreviated" href="mailto:kreiter@brain.uni-bremen.de">kreiter@brain.uni-bremen.de</a>) to receive detailed information.<br>
<br>
1 PhD Position - Code: Isee-Pawelzik<br>
(Project: I-See - Theoretical neuroscience in the group of Klaus
Pawelzik)<br>
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.<br>
<br>
1 PhD Position - Code: Bernstein-Ernst<br>
(Project: Berstein Award Udo Ernst - Electrophysiology)<br>
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
(<a class="moz-txt-link-abbreviated" href="mailto:kreiter@brain.uni-bremen.de">kreiter@brain.uni-bremen.de</a>), 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.<br>
