Research

Our research topics:

We study the neural basis of polarization-orientation and navigation (Schistocerca gregaria), the anatomy and function of the central complex in the desert locust (Schistocerca gregaria), and compare the distribution of neurotransmitters and neuropeptides across insect species.

Details on selected research topics:

Neural basis of polarization vision in the brain of desert locusts

Behavioral experiments in honeybees, ants, and other insects have shown that the polarization pattern of the blue sky serves an important role in insect compass navigation and spatial orientation. We investigate the neural mechanisms underlying polarized skylight navigation in the desert locust.
Organization and function of the central complex in the insect brain

The central complex is a group of interconnected neuropils in the center of the insect brain. It consists of the protocerebral bridge, the upper and lower divisions of the central body and a pair of posterior noduli. The most striking feature of this brain area is a highly modular arrangement of neural elements, forming series of layers and slices.
Anatomical and neurochemical organization of the insect brain

The insect brain is supplied with an astounding diversity of signalling molecules including neurotransmitters, neuromodulators, and neuropeptides. In order to understand the chemical compartmentalization of the brain and its constituent neuropils, we map the distribution of these substances.
Activity of locust brain neurons exposed to the natural sky

Many insects rely on sky compass signals for spatial orientation, e,g. during homing or seasonal migrations. Laboratory experiments in bees, beetles, locusts, crickets, butterflies and flies suggest that the central complex in the insect brain serves a role as an internal sky compass.
