Neuroscience

Tactile Conditioning And Movement Analysis Of Antennal Sampling Strategies In Honey Bees (Apis mellifera L.)

Samir Mujagić¹, Simon Michael Würth¹, Sven Hellbach¹, Volker Dürr¹

¹Biological Cybernetics, CITEC - Cognitive Interaction Technology - Center of Excellence, Bielefeld University

In this protocol we show how to condition harnessed honey bees to tactile stimuli and introduce a 2D motion capture technique for analyzing the kinematics of fine-scale antennal sampling pattern.

Chemistry

Analysis of Volatile and Oxidation Sensitive Compounds Using a Cold Inlet System and Electron Impact Mass Spectrometry

Jens Sproß¹

¹Department of Chemistry, Institute of Organic Chemistry, Bielefeld University

This video presents a protocol for the mass spectrometrical analysis of volatile and oxidation sensitive compounds using electron impact ionization. The presented technique is especially of interest for inorganic chemists, working with metal organyls, silanes, or phosphanes which have to be handled using inert conditions, such as the Schlenk technique.

The present article reviews an eye-tracking methodology for studies on language comprehension. To obtain reliable data, key steps of the protocol must be followed. Among these are the correct set-up of the eye tracker (e.g., ensuring good quality of the eye and head images) and accurate calibration.

Biochemistry

Förster Resonance Energy Transfer Measurements in Living Plant Cells

Sonja Michèle Schmidtpott¹, Thorsten Seidel¹

¹Dynamic Cell Imaging, Biochemistry and Physiology of Plants, Faculty of Biology, Bielefeld University

A protocol is provided for setting up a standard confocal laser-scanning microscope for in vivo Förster resonance energy transfer measurements, followed by data evaluation.
