1. Multichannel auditory processing in determining gaze direction ACG Progress Meeting 31 January 2008

2. Problem statement ›How to make a robot (iCat or observation camera) gaze at an attention requiring event detected through an auditory event.

3. Solution ingredients ›Robot control ›Sound recognition ›Sound localization

4. Approach ›Mixture of two approaches: Heuristical builds on work in the group derived from cognitive science Neuromimetic builds on my own computational neuroscience background

5. Necessary first step: ›Making multichannel auditory processing possible within cpsp-framework.

6. Multichannel processing ›Make like mechanism for treating feedforward dependencies: Representations (D.audio, D.E etc.) in role of build targets processSoundFunctions (read(m), calcEdB) in role of build rules ›Preserve existing signal processing functionality ›First iteration works offline ›Second iteration should work with live data

7. Demo

8. Outlook: ›Working with life data ›Heuristical approach Apply simple correlation methods on onsets categorized sound events to detect direction. ›Neuromimetic approach Create field of neurons in which different directions separate into different streams, mimicking function of the LSO and MSO areas.

9. Other continuing work ›Inhibitory molding during attention ›Carbachol induced oscillations ›Topology and firing patterns. (Write) ›Improved Carnevale-Hines algorithm. (Rewrite) ›Analytic solution of the BESTL model for dendritic branching. (Write) ›Influence of GABA-ergic development on visual cortical processing (Write, Remodel?)
