Astrocytes mediate analogous memory in a multi-layer neuron-astrocytic network [PDF]
arXiv, 2021 Modeling the neuronal processes underlying short-term working memory remains the focus of many theoretical studies in neuroscience. Here we propose a mathematical model of spiking neuron network (SNN) demonstrating how a piece of information can be maintained as a robust activity pattern for several seconds then completely disappear if no other stimuli

Amines, Astrocytes, and Arousal [PDF]
Neuron, 2017 Amine neurotransmitters, such as noradrenaline, mediate arousal, attention, and reward in the CNS. New data suggest that, from flies to mammals, a major mechanism for amine transmitter action is to raise astrocyte [Ca2+]i and release gliotransmitters that modulate neuronal activity and behavior.

Cell-autonomous clock of astrocytes drives circadian behavior in mammals
Science, 2019 Astrocytes can drive the master clock in the brain The neurons of the suprachiasmatic nucleus (SCN) of the hypothalamus function as a central circadian clock, coordinating mammalian physiology with the 24-hour light-dark cycle. Brancaccio et al.

Astrocytes are necessary for blood-brain barrier maintenance in the adult mouse brain
bioRxiv, 2020 In the adult brain, multiple cell types are known to produce factors that regulate blood-brain barrier properties, including astrocytes. Yet several recent studies disputed a role for mature astrocytes at the blood-brain barrier.

Breathing cluster in complex neuron-astrocyte networks [PDF]
arXiv, 2023 Brain activities are featured by spatially distributed neural clusters of coherent firings and a spontaneous switching of the clusters between the synchrony and asynchrony states. Evidences from {\it in vivo} experiments suggest that astrocytes, a type of glial cell regarded previously as providing only structural and metabolic supports to neurons ...

Motor‐Free Soft Robots for Cancer Detection, Surgery, and In Situ Bioprinting
Advanced Healthcare Materials, EarlyView.Novel motor‐free soft robots for cancer detection, surgery, and in situ bioprinting–are presented. This master‐slave system is constructed from soft fibrous syringe architectures, removing the need for electrical motors and complex control mechanisms, while reducing the physical tremors.

Bayesian inference and role of astrocytes in amyloid-beta dynamics with modelling of Alzheimer's disease using clinical data [PDF]
arXiv, 2023 Alzheimer's disease (AD) is a prominent, worldwide, age-related neurodegenerative disease that currently has no systemic treatment. Strong evidence suggests that permeable amyloid-beta peptide (Abeta) oligomers, astrogliosis and reactive astrocytosis cause neuronal damage in AD.

Flexible 3D Kirigami Probes for In Vitro and In Vivo Neural Applications
Advanced Materials, EarlyView.A customizable and scalable approach to fabricate flexible 3D kirigami microelectrode arrays (MEAs) featuring up to 128 shanks, including surface and penetrating electrodes designed to interact with the 3D space of neural tissue, is presented. The 3D kirigami MEAs are successfully deployed in several neural applications, both in vitro and in vivo, and ...
