We are interested in the mechanisms and structures underlying the activity dynamics in neuronal networks and the processing of neuronal activity within the network. In joint projects with computational neuroscientists we investigate how the biological neuronal networks process incoming stimuli, what determines intrinsic activity, how pathological dynamics arise and how to contain them. To address these questions we use acute brain slices, cell cultures and animal models with a variety of techniques. A central technology is extracellular recording the neuronal activity with microelectrode arrays to analyze the spatio-temporal structure of activity. Recordings with these arrays are combined with paired intracellular recordings, calcium imaging, microstimulation and advanced data analyses. New technical and analysis tools are developed as needed in collaborations with microsystems engineers. This work is embedded in the Bernstein Center for Computational Neuroscience Freiburg (BCCN Freiburg) and the new Bernstein Focus Neurotechnology - Freiburg/Tuebingen. The successful candidate is expected to contribute to the teaching and training program of these iniatives. Candidates should have outstanding academic records and an interest in translational neuroscience and neurotechnology. The position is open immediately until filled.

Plasticity Revisited: Motivating New Algorithms Based On Recent Neuroscience Research June 14, 2009, 10:30-12:30, Atlanta, Georgia, USA Tutorial Page: http://reason.cs.uiuc.edu/tsvi/IJCNN-tutorial-2009.html ----------- Plasticity is a key component of computational algorithms and neuroscience studies.  Neuroscience research reveals a wide variety of plasticity mechanisms – i.e. homeostatic, synaptic (fast, slow, NMDA dependent etc.), and intrinsic plasticity.  However, controversies still surround plasticity. How is plasticity governed and why is there so much variability? Can these findings be interpreted differently? Feedback inhibition, where neurons feed back to their own inputs and inhibit them, is found throughout the brain including sensory processing regions.  Within feedback networks, mechanisms required for plasticity are fundamentally different. We will analyze plasticity from the perspective of feedback inhibition, review basic assumptions about plasticity, and motivate new recognition algorithms.

I am going to be working on anaesthetized animals, so I don't need mercury swivels or anything. Small screws seem like a good way, electrode and attachment system in one (with a bit of dental cement). But then how does one attach the leads to the screw? I can think of numerous ways, such as solder on a 1mm plug (but this could break), use a lead washer (but this would spread the recording area), just clip on an aligator clip (could pop off). Anybody got any tried and true methods? Thanks.
