Spreading depolarization (SD) is a slow propagating wave of strong depolarization of neural cells, implicated in several neuropathological conditions. The breakdown of brain homeostasis promotes significant hemodynamic and metabolic alterations, which impacts on neuronal function. In this work we aimed to develop an innovative multimodal approach, encompassing metabolic, electric and hemodynamic measurements, tailored but not limited to study SD. This was based on a novel dual-biosensor based on microelectrode arrays designed to simultaneously monitor lactate and glucose fluctuations and ongoing neuronal activity with high spatial and temporal resolution. In vitroevaluation of dual lactate-glucose microbiosensor revealed an extended linear range, …

The retrosplenial cortex (RSC) is a centrally located brain region that has reciprocal connections with several brain regions important for memory, including the prefrontal cortex, para-hippocampal region, hippocampal formation, and rhinal cortices. The RSC is also well connected with structures important for sensory processing, including the parietal cortex, thalamus, and visual cortices. Due to this connectivity, and early evidence that suggests the RSC plays a critical role in learning and memory, the region has recently gained much more research attention. Early studies found that patients with brain damage that includes the RSC have difficulty with verbal and visual information, retrieving …
