Abstract:
The question of olfactory information processing inside the olfactory bulb neural network is addressed. Specific behaviors such as LFP oscillations and phase-locking neural activity are studied. We firstly analyzed biological data from olfactory bulb slices. We explore the phasing properties of multi and single-units related to the LFP signal. We develop a new method based on neural models and drugs injection to estimate the conductances time course. We find a relation between inhibitory conductance and spike timing phase-locking. We summarized those biological informations in a computer model. We mathematically define the influence of fluctuating inhibitory events reception on the spike time precision. We then explore the dynamical and computational properties of this artificial network. We adapt those computational properties into an artificial nose in order to recognize odors from artificial sensors.
The talk is open to the public. Guests are cordially invited!
