CICADA: A unified framework for NWB-based neurophysiological data analysis

Myriam Hamon, Jules Lebert, Julien Denis, Caroline Filippi et autres

ABSTRACT Neurophysiology datasets are becoming increasingly complex, combining behavioral measurements with high-dimensional neuronal activity recordings coming from optical and/or electrophysiological measurements. The Neurodata Without Borders (NWB) standard has emerged in the community as the format of record. While standardized and widely used …

Distinct developmental trajectories of externally and internally generated hippocampal sequences and assemblies

Erwan Leprince, Caroline Filippi, Manon Mantez, Robin F. Dard et autres

The hippocampus generates cognitive maps through two distinct mechanisms: external representations anchored to environmental landmarks and internal sequences integrating self-referenced information. In adult CA1, these functions segregate radially, with deep cells processing external cues and superficial cells handling internal representations. This anatomical …

Protocol to image and analyze hippocampal network dynamics in non-anesthetized mouse pups

Mirindra R. Ratsifandrihamanana, Robin F. Dard, Julien Denis, Rosa Cossart et autres

Two-photon calcium imaging is a powerful technique that has revolutionized our understanding of how neural circuit dynamics supports different behaviors and cognitive processes. However, performing imaging during development remains challenging. Here, we provide a protocol to image CA1 neurons in mouse pups …

The rapid developmental rise of somatic inhibition disengages hippocampal dynamics from self-motion

Robin F. Dard, Erwan Leprince, Julien Denis, Shrisha Rao Balappa et autres

Early electrophysiological brain oscillations recorded in preterm babies and newborn rodents are initially mostly driven by bottom-up sensorimotor activity and only later can detach from external inputs. This is a hallmark of most developing brain areas, including the hippocampus, which, in the …

Extrinsic control of the early postnatal CA1 hippocampal circuits

Erwan Leprince, Robin F. Dard, Salomé Mortet, Caroline Filippi et autres

SUMMARY The adult CA1 region of the hippocampus produces coordinated neuronal dynamics with minimal reliance on its extrinsic inputs. In contrast, the neonatal CA1 is tightly linked to externally-generated sensorimotor activity but the circuit mechanisms underlying early synchronous activity in CA1 remain …

The rapid developmental rise of somatic inhibition disengages hippocampal dynamics from self-motion

Robin F. Dard, Erwan Leprince, Julien Denis, Shrisha Rao-Balappa et autres

ABSTRACT Early electrophysiological brain oscillations recorded in preterm babies and newborn rodents are initially mostly ignited by bottom-up sensorimotor activity and only later can detach from external inputs. This is a hallmark of most developing brain areas including the hippocampus, which in …

DeepCINAC: A Deep-Learning-Based Python Toolbox for Inferring Calcium Imaging Neuronal Activity Based on Movie Visualization

Julien Denis, Robin F. Dard, Eleonora Quiroli, Rosa Cossart et autres

Two-photon calcium imaging is now widely used to infer neuronal dynamics from changes in fluorescence of an indicator. However, state-of-the-art computational tools are not optimized for the reliable detection of fluorescence transients from highly synchronous neurons located in densely packed regions such …
