Variation and development of the turtle chondrocranium, with a description of the common musk turtle (Sternotherus odoratus, Kinosternidae, Cryptodira, Testudines)

open access: yesThe Anatomical Record, EarlyView., 2023
Abstract Based on histological cross‐sections, the chondrocranium of the common musk turtle (Sternotherus odoratus) was reconstructed, described, and compared with other turtles. It differs from that of other turtle chondrocrania by possessing elongated, slightly dorsally orientated nasal capsules with three dorsolateral foramina, which might be ...

Hypothalamus-Olfactory System Crosstalk: Orexin as a Connecting Track in Mice.

open access: yesFrontiers in Neuroanatomy, 2012
It is well known that olfaction influences food intake, and almost vice versa, the nutritional status of individuals modulates olfactory sensitivity. However, the neuronal correlate of this relationship and the connections between the olfactory bulb and ...

3D In Vitro Glioma‐Neuron‐Astrocyte Biomimetic Composites Recapitulate Key Molecular Mechanisms Linked to Glioblastoma Multiforme Pathophysiology

open access: yesAdvanced Functional Materials, EarlyView.
Glioblastoma multiforme is the most devastating and incurable brain tumor. To better study this disease, a 3D model is developed using a hyaluronic acid‐based hydrogel combined with a multicellular approach. This model recapitulates in vivo brain stiffness, cell‐extracellular matrix and cell‐cell interactions and the tumor's hijacking function with the

Neuroanatomical study of the podocnemidid turtle Neochelys arenarum (Pleurodira), from the early Eocene of France

open access: yesThe Anatomical Record, EarlyView., 2023
Abstract Neochelys is an exclusively European Eocene podocnemidid genus belonging to a linage that reached this continent at the early Eocene. The so far available anatomical information about it is relatively abundant, especially considering that of its shell, at least partially preserved for the eight valid species currently considered.

Odorant Receptors Signaling Instructs the Development and Plasticity of the Glomerular Map

open access: yesNeural Plasticity, 2015
The olfactory system provides a great opportunity to explore the mechanisms that underlie the formation and function of neural circuits because of the simplicity of its structure.

3D standard brain of the red flour beetle Tribolium castaneum: a tool to study metamorphic development and adult plasticity

open access: yesFrontiers in Systems Neuroscience, 2010
The red flour beetle Tribolium castaneum is emerging as a further standard insect model beside Drosophila. Its genome is fully sequenced and it is susceptible for genetic manipulations including RNA-interference.

An Optoelectrically Switched, Dual‐Mode Neuromorphic Sensor for Transient and Accumulative Gas Detection

open access: yesAdvanced Functional Materials, EarlyView.
A transistor‐type carbon nanotube gas sensor with dual‐mode detection capability has been proposed. By simply adjusting the gate voltage and UV illumination, this sensor enables both real‐time detection and accumulation‐based sensing of toxic gases within a single device, providing a compact and adaptable platform for environmental monitoring ...

Nasal Placode Development, GnRH Neuronal Migration and Kallmann Syndrome

open access: yesFrontiers in Cell and Developmental Biology, 2019
The development of Gonadotropin releasing hormone-1 (GnRH) neurons is important for a functional reproduction system in vertebrates. Disruption of GnRH results in hypogonadism and if accompanied by anosmia is termed Kallmann Syndrome (KS).

A Wireless Cortical Surface Implant for Diagnosing and Alleviating Parkinson's Disease Symptoms in Freely Moving Animals

open access: yesAdvanced Healthcare Materials, EarlyView.
A wireless cortical surface implant employing graphene electrode arrays diagnoses and alleviates Parkinson's disease symptoms in freely moving animals. The device continuously monitors cortical activity and delivers targeted stimulation, restoring beta–gamma and delta oscillations.

Inhibition of oxidative stress in cholinergic projection neurons fully rescues aging-associated olfactory circuit degeneration in Drosophila

open access: yeseLife, 2018
Loss of the sense of smell is among the first signs of natural aging and neurodegenerative diseases such as Alzheimer’s and Parkinson’s. Cellular and molecular mechanisms promoting this smell loss are not understood.
