Title of the talk:
Neurogenic control of neurovascular coupling.


[well type=””]


The cerebral cortex comprises diverse areas involved in perception, movement or cognition. In spite of this functional diversity, the cortical network is formed with the repetition of a microcircuit. This microcircuit contains excitatory and inhibitory neuronal types. The neuronal activity of this microcircuit, its local cerebral blood flow and metabolism are tightly coupled to match the increased energy needs occurring during neuronal processing. This neurovascular and neurometabolic coupling, essential to normal brain function and integrity, is also the physiological basis of the hemodynamic contrasts widely used to map neuronal activity in health and disease. A major goal of Bruno Cauli’s laboratory is to understand how the microcircuit controls its own energy supply and metabolism via interactions with the glio-vascular network. These points are addressed at the molecular, cellular and network levels in rodent cortical slices. Patch-clamp electrophysiology often combined with single cell RT-PCR and histochemistry is the central methodology of the lab. Viral transfer or transgenic mice are also used to express various genes of interest in cell types. Among these genes, the light-operated channelrhodopsin are used to excite specific neuronal types and evaluate their influence on the glio-vascular network. Diverse bioluminescent or fluorescent genetically-encoded sensors are also to image metabolic activities at the cellular and multicellular levels.
