Ultra‐Flexible µ‐ECoG Arrays Based on PEDOT:PSS Micropillars

Advanced Materials Interfaces, EarlyView.
This work demonstrates an efficient procedure for fabricating ultra‐flexible neural interfaces endowed with micropatterned microelectrodes to increase surface area and characterized by extremely low impedance values to enable high‐quality recordings. The home‐built device has been shown to record somatosensory evoked potentials in vivo with exceptional

Biological and Mechanical Limitations for Chronic Fast‐Scan Cyclic Voltammetry Sensor Design

Advanced Materials Technologies, EarlyView.
Real‐time detection of neurochemicals has demonstrated value in the field of neuroscience. However, current methods have limitations for use in the chronic setting, which is often the ideal environment for research. This article discusses these limitations, as well as technologies that have been developed to overcome them, and provides recommendations ...

3D transcranial Dynamic Ultrasound Localization Microscopy in the mouse brain using a Row-Column Array [PDF]

arXiv
The role of brain hemodynamics in neurodegenerative diseases cannot be fully assessed using existing imaging technologies. Recently, 2D Dynamic Ultrasound Localization Microscopy (DULM) has allowed for the quantitative mapping of the pulsatile flow at sub-wavelength resolution. However, to obtain accurate velocity estimates, 3D imaging is more adapted,

Nanoparticles Combining Host‐Directed Therapeutics and Antibiotics to Boost Bacterial Killing and Overall Survival of Zebrafish Embryos Infected with Mycobacterium Marinum

Advanced Therapeutics, EarlyView.
This study investigates the combination of host‐directed therapeutics (HDT) with antibiotics in a single polymeric micelle based on polypept(o)ides for the therapy of Mycobacterium tuberculosis (Mtb) and ‐marinum (Mm) infections. When the HDT and antibiotic are co‐encapsulated, it significantly reduces bacterial burden in cells and improves overall ...

Upconversion‐Based Remote Deep Brain Modulation for Therapeutic Dissection of Parkinson's Disease

Advanced Therapeutics, EarlyView.
An upconversion‐based wireless optogenetic strategy enables an all‐optical deep brain modulation solution for treating Parkinson's disease in rodent animals without using electronics or any tethered cables, providing experimental evidence supporting a therapeutic mechanism of STN‐DBS by disruption of anterograde signal transmission along the indirect ...

Neural Plasticity and Hearing‐Speech Development in Children with Auditory Brainstem Implants for Congenital Hearing Loss Due to Severe Inner Ear Malformation

Advanced Science, EarlyView.
Data from a prospective cohort with 112 auditory brainstem implant users are analyzed. Younger age at implantation (<3 years), less severe inner‐ear malformation (common cavity, cochlear aplasia, and hypoplasia), and more intraoperative eABR evoked electrodes (≥60%) are associated with better hearing and speech outcomes.

Multi-Agent Deep Reinforcement Learning for Multiple Anesthetics Collaborative Control [PDF]

arXiv
Automated control of personalized multiple anesthetics in clinical Total Intravenous Anesthesia (TIVA) is crucial yet challenging. Current systems, including target-controlled infusion (TCI) and closed-loop systems, either rely on relatively static pharmacokinetic/pharmacodynamic (PK/PD) models or focus on single anesthetic control, limiting ...

Sensory Encoding Alternates With Hippocampal Ripples across Cycles of Forebrain Spiking Cascades

Advanced Science, EarlyView.
This study reveals widespread, coordinated brain activity during passive visual stimulation in mice. Sensory coding, phase‐locked with the periodic dynamics, shows an inverse relationship to hippocampal ripples. The results suggest that periodic brain activity spurs alteration between two distinct operational modes of brain, facilitating exteroceptive ...

Programmable NIR Responsive Nanocomposite Enables Noninvasive Intratympanic Delivery of Dexamethasone to Reverse Cisplatin Induced Hearing Loss

Advanced Science, EarlyView.
In this study, saponin‐coated silica@gold nanocarriers responsive to NIR radiation is developed to enhance intratympanic drug delivery for cisplatin‐induced hearing loss (CIHL) treatment. The biocompatibility and oto‐protective properties are validated both in vitro and in vivo.

Apoptotic Vesicles Derived from Mesenchymal Stem Cells Ameliorate Hypersensitivity Responses via Inducing CD8+ T Cells Apoptosis with Calcium Overload and Mitochondrial Dysfunction

Advanced Science, EarlyView.
The therapeutic potential of ApoVs derived from stem cells from human exfoliated deciduous teeth (SHED‐ApoVs) in the treatment of CD8+ T cell‐mediated hypersensitivity reactions is noteworthy. SHED‐ApoVs are capable of fusing with the plasma membrane of CD8+ T cells, which subsequently triggers a series of events characterized by calcium overload ...
