Organic Thin‐Film Transistors for Neuromorphic Computing

Advanced Electronic Materials, EarlyView.
Organic thin‐film transistors (OTFTs) are reviewed for neuromorphic computing applications, highlighting their power‐efficient, and biological time‐scale operation. This article surveys OFET and OECT devices, compares them with memristors and CMOS, analyzes how fabrication parameters shape spike‐based metrics, proposes standardized characterization ...

Physiological features of parvalbumin-expressing GABAergic interneurons contributing to high-frequency oscillations in the cerebral cortexA. Synaptic Integration Before Axon.B. Synaptic Delay After Axon.

Current Research in Neurobiology
Parvalbumin-expressing (PV+) inhibitory interneurons drive gamma oscillations (30–80 Hz), which underlie higher cognitive functions. In this review, we discuss two groups/aspects of fundamental properties of PV+ interneurons.

Capacitive versus Faradaic Microelectrodes for Extracellular Stimulation: A Fully Coupled FEM–Hodgkin–Huxley Study of Thresholds and Current Redistribution

Advanced Electronic Materials, EarlyView.
A fully coupled FEM–HH model shows that ideally capacitive microelectrodes can achieve lower charge‐density thresholds than Faradaic contacts under current‐controlled stimulation. The advantage stems from the dynamics of surface current density on capacitive interfaces, which redirects current beneath adherent neurons.

Molecular mechanism of ischemic postconditioning in promoting diabetic ischemic brain injury repair via the microRNA‐34a–BDNF–SIX3 signaling axis

Animal Models and Experimental Medicine, EarlyView.
Diabetes combined with ischemic stroke (DMIS) exacerbates brain infarct size and neuronal damage compared to nondiabetic ischemic stroke (IS). This study reveals that microRNA‐34a (miR‐34a) plays a key role in DMIS pathogenesis: miR‐34a directly targets and suppresses brain‐derived neurotrophic factor (BDNF) and Sine oculis homeobox 3 (SIX3), promoting

Conditioning Electrical Stimulation for Patients with Moderate or Severe Carpal Tunnel Syndrome: Double Blinded Randomized Controlled Trial

Annals of Neurology, EarlyView.
Objective Carpal tunnel syndrome (CTS) can drastically impair one's ability to work and interferes with activities of daily living. We recently demonstrated that, in rodents, conditioning electrical stimulation (CES) delivered to the nerve 7 days prior to surgery imparts a conditioning lesion‐like effect by accelerating the rate of regeneration along ...

Predominance of Ferroptotic Cell Death Mechanisms in Substantia Nigra Neurodegeneration in Parkinson's Disease

Annals of Neurology, EarlyView.
Objective The extent of neuronal loss in Parkinson's disease (PD) and the pathogenic processes underlying neuronal dysfunction and loss remain poorly understood. Here, we analyzed the expression of key molecules representing different cell death signaling pathways and their association with Lewy pathology, dopaminergic (DA) neuron loss and stage of PD ...

The Dynamics of Neurofilament Light Chain in Spinal Muscular Atrophy

Annals of Neurology, EarlyView.
Objective Newborn screening (NBS) for spinal muscular atrophy (SMA) facilitates early diagnosis and treatment for affected individuals. However, fluid biomarkers that provide early insights into disease activity and outcomes in a neonatal cohort and those unable to access (due to reimbursement criteria) or deferring immediate treatment are lacking ...

Fast‐Track to Functional Neurons: Accessible and Minimalistic Neurogenin 2 Programming of Human iPSCs

Advanced NanoBiomed Research, EarlyView.
Fast‐track to functional human induced pluripotent stem cell (hiPSC)‐derived neurons: This colony‐initiated differentiation approach induces neurogenin 2 overexpression in dense hiPSC colonies (day 0), resulting in a structural reorganization of the colonies (day 2) before they are replated as single cells.

A Cost‐Effective Hybrid Method For Homogeneous Matrix Coating in Matrix‐Assisted Laser Desorption/Ionization Mass Spectrometry Imaging Using Simultaneous Spin and Spray Deposition

Analysis &Sensing, EarlyView.
This study introduces an in‐house spin coater for matrix‐assisted laser desorption/ionization mass spectrometry imaging, providing homogeneous matrix deposition via simultaneous spray and spin. The approach yields reproducible signals and clear metabolite distributions in complex tissues.

Neuroanatomical diversity in Teleocichla with new volumetric and histological insights into the encephalon of Teleocichla monogramma Kullander 1988

The Anatomical Record, EarlyView.
Abstract Teleocichla comprises small cichlids that inhabit the rapid streams of Amazonian rivers; however, there has been limited research on their encephalon morphology. This study examined the neuroanatomy of four species, focusing on volumetric measurements of their encephalon subregions, and providing a histological description of the encephalon of
