What shape is an odor? Video segmentation on honeybee brain recordings

Martin Strauch, Julia Rein, Informatik/Neurobiologie, Universität Konstanz

In the honeybee brain, odors are represented as spatio-temporal 
activity patterns that we can record with the calcium-imaging technique.

Experiments aimed at understanding olfactory processing in the brain 
require methods to automatically extract these patterns from large 
volumes of video recordings.
We present algorithms for the efficient factorisation of movie matrices
into biologically meaningful components and report on recent experimental data
