Our agreement was, to continue our seminar for phd students and other institute members in a similar way as last semester. We will meet this week on thursday, Oct. 3, at 16:15 in the seminar room to discuss your selection for paper presentations, and dates for talks.

In particular, we want to continue the light journal-club-like style of presentations of work by others, where the presenter has read the paper, and can perhaps show some figures from the paper, but otherwise mainly directs the discussion of the paper (assuming that all participants have looked before into the presented paper).

In addition, we want to continue the tradition of short informal presentations of own research results and problems on the blackboard. This semester we also want to schedule these presentations in advance, but no ppt slides should be shown (except for rare cases where figs that could not possibly be reproduced on the blackboard), and excessive preparation is not desired. If you aim at about 20min presentation time, this will in general be ok (leaving plenty of time for discussion).

Robert (strand computing, and particle filters), Florian (he should report the strategy of his work, and a bit on the preceding NIPS paper by Roelfsema, SHS (theory for CSP), Elmar (movement planning through neural sampling), David (motor control through neural sampling), Christoph (Ca-imaging data analysis), Dejan (learning BNs), Gernot (networks of sWTA's) are all working on interesting new topics, and should give a presentation before they get down to write the final version of a paper on the results (which suggests in most cases a presentation in Oct or Nov).

Either type of presentation should not last longer than 35 or at most 40 minutes.

In the following I have listed a few papers that either contain a new perspective, or contribute to our understanding of microcircuits (esp. role of inhibition, and how sensory input arrives there), and high level organization of brain computations:


-----------------------------------

In addition Robert has selected some options for papers on Reinforcement learning in the brain, especially on the interplay of model-based and model-free RL in the brain:
