About his PhD project

Most brain functions are encoded by specific neuronal activity patterns with characteristic temporal and spatial dynamics. This proposal will focus on the hippocampus, a brain region supporting memory and encoding spatial and temporal information. Hippocampal dynamics result from the interaction between self-organized internal dynamics and various external inputs from the environment. We want to know how development shapes the final functional organization of adult hippocampal networks: do they self-organize through the interaction of active neurons or do they emerge in reference to a blueprint determined by early developmental programs like genetic factors? To image and record the deep hippocampus neuron activity we have been developing an ultra-thin flexible endoscope that is able to perform 2-photon imaging deep in the brain at depth location that are inaccessible using 2-photon microscopy.
