3D immersive visualization of a Copepode

Rendering of a Copepod anatomy based on light sheet microscopy data. 3D immersive visualization in the CAVE environment at High Performance Computing Center Stuttgart (HLRS) in Stuttgart allows co-located and distant collaborative exploration of spatial relationships, and direct interaction with the visualizations and simulations.

Analysis of Hydras contraction

Quantitative analysis of Hydra spontaneous contractile behavior. The animation explains the automatized video-recording of a freely behaving polyp and further analysis of the image sequence using a custom script to generate such metrics of the behavior as stretching and contractile capacity, contraction frequency and regularity.

The contraction behavior in Hydra

Example of Hydra spontaneous body contractions (65x acceleration). The spontaneous contractions are shrinkages of the body column that occur periodically in the absence of any exogenous stimuli.
