Neuromodulation of cricket auditory behaviour

Neuromodulation of cricket auditory behaviour

Supervisor: Dr Berthold Hedwig

Project summary:

Neuromodulation by amines changes aggressive behaviour in crickets or crustaceans. We expected that also female phonotactic behavior is under control of neuromodulatory substances, this however has not been investigated.

What the student will be doing:

We will use a trackball system to record phonotactic behaviour in crickets before and after the systemic application of amines (e.g octopamine, dopamine or serotonin) and we will analyse if the neuromodulators had an increasing or decreasing effect on the behaviour.
