Feature Detecting Brain Neurons for Auditory Pattern Recognition in Crickets
Project supervisor: Dr Berthold Hedwig
Acoustic communication with species-specific signals requires neuronal networks in the auditory pathway of the receiver that specifically respond to the communication signal, these are called “feature detectors”. We have identified a pattern recognition network in the brain of female crickets with feature detecting neurons that specifically respond to the male calling song. The next step of this project aims at comparing this network across different species to analyze to which extend the properties of the network are adapted to the temporal structure of the different species-specific songs. Training will be provided in intracellular recordings, confocal imaging, neuroanatomical tracing methods and behavioral studies.
