Project title: Functional role of adaptation and neural noise for population coding
Summary: For this project we have proposed to elucidate the role of oscillations for integration of sensory inputs, using the paradigm of olfactory perception. Neuronal population activity in the olfactory bulb is shaped by both slow, theta-like oscillations that are coupled to the animal’s respiration cycle, and fast gamma oscillations that are thought to be relevant for olfactory coding. There is accumulating evidence that the fast oscillations are generated at the reciprocal mitral cell - granule cell synapse, which constitutes the largest fraction of synapses in the olfactory bulb and our focus of interest for the past 10 years. Both types of oscillations, gamma and theta, are known to be coupled in vivo.
