Background and activities
The research group aims at understanding how the brain processes olfactory information, i.e. how signals initiated by specific odors are encoded in a functional neural network.
By studying a suitable model object, the moth brain, we map how the neural network constituting distinct synaptic levels of the olfactory pathway is connected, and how biologically relevant odor stimuli influence the activity in individual neurons and neuron populations.
Methods: Experimental lab activities, including intracellular recordings/stainings combined with confocal microscopy and modelling of neural structures via data visualization software; immunocytochemistry; calcium imaging.
