Precise timing of action potentials is crucial for processing sensory information. Axonal length and propagation speed largely determine the time necessary for action potentials to reach postsynaptic neurons. Within the retina, retinal ganglion cell (RGC) axons form the retinal nerve fiber layer (RNFL), a highly…

Neuronal morphology plays a fundamental role in determining the neuronal network's function. However, understanding the effect of single neuron morphology on whole-brain function is still an open challenge. Limited by resolution and time cost, current studies on the functional properties of whole-brain connectivity…

Feedback mechanisms are pervasive across the nervous system, regulating neural networks through the backpropagation of information at different levels. Neuroanatomical data have shown the presence of feedback neurons within the visual system of $\textit{Drosophila}$, where information such as visual motion is…

The fusiform gyrus (FG) in the human brain is essential for higher cortical functions such as recognizing faces and human bodies [1, 2]. Though, the relationship of its structural and functional decompositions in the anterior portion is yet to be better understood [3]. Here, the anterior FG was investigated in ten…

Understanding how tasks are processed across the entire brain is a central yet complex question in neuroscience. Recently, the release of brainwide electrophysiological recordings in a standardized behavior task offers an unprecedented opportunity to approach this question. In this paper, we characterize the signal…

The secondary motor cortex (M2) of rodents appears as a highly integrative brain region, with functions beyond motor processing. It indeed features prefrontal-like thalamocortical connectivity, with prominent innervation from thalamic nuclei involved in adaptive decision-making, namely the mediodorsal thalamic nucleus…

Glial cells show great diversity and differ in terms of their functional roles. Microglia, oligodendrocytes, and astrocytes interact with neurons and thus ensure the functionality of the neurons. However, little is known about how they interact with different neuronal cell types. We investigate glial and neuronal…

Comparative neuroanatomy has been a challenging research field, even with the methodological innovations in recent years. In this context, cortical surface reconstructions emerged as a new venue to provide further insights on brain morphology, but they are mostly limited to humans and a few other primates, hindering a…

The lymphatic vessels (LVs) contribute to tissue homeostasis and function by facilitating the clearance of excess fluid and macromolecules from the interstitial tissue of the brain. Various routes for the extracranial transport of LV drainage from the brain parenchyma to the deep cervical lymph nodes were described.…

Brain atlases like the Allen Mouse Brain Common Coordinate Framework (CCFv3) are essential tools to guide the integration of different sources of neuroscience data. In this study, we introduce a novel method for curating brain atlas regions that leverages the strength of Houdini and Python software. This approach…

Background: Folate supplementation throughout pregnancy is recommended to support foetal and early postnatal brain development. The exact effect of folate on cerebellar development is unknown. This study looked at how maternal folate consumption impacts the structural development of the offspring's cerebellar…

The evolution and development of all organisms on earth relies on near-constant gravity. Experimental manipulations can create developmental conditions that have never been encountered during evolution, yet reveal developmental mechanisms based on informative phenotypic outcomes; classically, such experiments include…

We used dense (20 m site spacing) local field potential (LFP) and single unit recordings across all layers of the gRSC concurrent with CA1 LFP recordings in behaving mice to investigate circuit activity of high-frequency oscillations (HFOs) in theta and sharp wave-ripples (SWRs). By comparing HFOs occurring at times…

The generating mechanism for the gyrification of the mammalian cerebral cortex remains a central open question in neuroscience. Although many models have been proposed over the years, very few were able to provide empirically testable predictions. In this paper, we assume a model in which the cortex folds for all…

The shapes of neuronal morphologies are essential for the dynamical properties of the brain, as their branching patterns govern different functional properties of cell types. However, disagreements on the definition of neuronal classes due to the subjective views of the experts have spawned several efforts to find an…

Sensations often trigger movements, but one’s movements also generate sensory experience. Vestibular organs monitor head movements and contribute to the brain’s ability to distinguish between self- and externally-generated sensory stimuli. Signals from the vestibular organs are broadcasted throughout the brain,…
