Combining cortical voltage imaging and hippocampal electrophysiology for investigating global, multi-time scale activity interactions in the brain [PDF]
arXiv, 2021 A new generation of molecular tools for analyzing neural activity has been contributing to elucidate classical open questions in neuroscience. With enhanced GEVIs and advanced optical imaging techniques, voltage-imaging technologies have been increasingly used to observe the dynamics of large circuits.

Fecal Short-Chain Fatty Acids as Potential Biomarkers for Attention-Deficit/Hyperactivity Disorder
European Psychiatry, 2023 Introduction Growing evidence supports a possible link between gut microbiota and attention-deficit/hyperactivity disorder (ADHD) via the gut-brain axis. Short-chain fatty acids (SCFAs), the major metabolites produced by gut microbiota through anaerobic

Electric Pulse Regulated MXene Based Nanozymes for Integrative Bioelectricity Immuno‐Cancer Therapy
Advanced Functional Materials, EarlyView.MXenzyme‐mediated bioelectricity cancer therapy (MXenzyme‐BECT) enhances cancer cell death through irreversible depolarization, ion channel disruption, ROS generation, and immunogenic cell death. Computational simulations reveal the electrical mechanisms by which MXenzyme acts on single cells and support to predict treatment parameters. Next‐generation

Autism Research, Volume 15, Issue 12, Page 2250-2264, December 2022., 2022 Abstract A growing body of research suggests that locus coeruleus‐norepinephrine (LC‐NE) system may function differently in individuals with autism spectrum disorder (ASD). Understanding the dynamics of both tonic (resting pupil diameter) and phasic (pupil dilation response [PDR] and event‐related potential [ERP]) indices may provide meaningful ...

On the reconstruction of cavities in a nonlinear model arising from cardiac electrophysiology [PDF]
arXiv, 2022 In this paper, we deal with the problem of determining perfectly insulating regions (cavities) from one boundary measurement in a nonlinear elliptic equation arising from cardiac electrophysiology. Based on the results obtained in [9] we propose a new reconstruction algorithm based on $\Gamma$-convergence.

Development of a Novel Platform for in vitro Electrophysiological Recording [PDF]
arXiv, 2022 This PhD thesis introduces the concept of meta-electrodes coupled with laser optoporation for high quality intracellular signals from hiPSCs-CM. These signals can be recorded on high-density commercial CMOS-MEAs from 3Brain characterized by thousands of electrode covered by a thin film of porous Platinum without any rework of the devices, 3D ...
