Functional Topography and Development of Inhibitory Reticulothalamic Barreloid Projections

Kazuo Imaizumi; Yuchio Yanagawa; Guoping Feng dkk.

Frontiers in Neuroanatomy, Vol. 12 · 2018 · Inggris · DOAJ Scopus

The thalamic reticular nucleus (TRN) is the main source of inhibition to the somatosensory thalamus (ventrobasal nucleus, VB) in mice. However, the functional topography and development of these projections with respect to the VB barreloids has been largely unexplored. In this respect, to assist in…

Micro- and Nanotopography Sensitive Bacterial Attachment Mechanisms: A Review

Yifan Cheng; Guoping Feng; Carmen I. Moraru

Frontiers in Microbiology, Vol. 10 · 2019 · Inggris · DOAJ Scopus

Bacterial attachment to material surfaces can lead to the development of biofilms that cause severe economic and health problems. The outcome of bacterial attachment is determined by a combination of bacterial sensing of material surfaces by the cell and the physicochemical factors in the…

The Role of Muscle microRNAs in Repairing the Neuromuscular Junction

Gregorio Valdez; Mary P. Heyer; Guoping Feng dkk.

PLoS ONE, Vol. 9 No. 3 · 2014 · Inggris · PLOS Scopus

microRNAs have been implicated in mediating key aspects of skeletal muscle development and responses to diseases and injury. Recently, we demonstrated that a synaptically enriched microRNA, miR-206, functions to promote maintenance and repair of the neuromuscular junction (NMJ); in mutant mice…

Study on the pulsation characteristics of Roots-type hydrogen circulation pump suppressed by a twisted-blade rotor

Guoping Feng; Jing Yao; Xihuizi Liang dkk.

AIP Advances, Vol. 15 No. 11 · 2025 · Inggris · DOAJ Scopus

A novel twisted-blade rotor was developed for Roots-type hydrogen circulation pumps to suppress pressure and flow pulsations while maintaining high flow efficiency. Three-dimensional unsteady simulations were conducted and validated through experiments, with results showing an error below 2%. The…

Fluorescent Labeling of Newborn Dentate Granule Cells in GAD67-GFP Transgenic Mice: A Genetic Tool for the Study of Adult Neurogenesis

Shengli Zhao; Yang Zhou; Jimmy Gross dkk.

PLoS ONE, Vol. 5 No. 9 · 2010 · Inggris · PLOS Scopus

Neurogenesis in the adult hippocampus is an important form of structural plasticity in the brain. Here we report a line of BAC transgenic mice (GAD67-GFP mice) that selectively and transitorily express GFP in newborn dentate granule cells of the adult hippocampus. These GFP+ cells show a high…

LLM-Enhanced Multimodal Perception Data Fusion and Cascaded Augmentation for Crop Growth Monitoring Based on UAV Remote Sensing

Xihuizi Liang; Ruihong Jing; Yueye Yong dkk.

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, Vol. 19 · 2026 · Inggris · DOAJ Scopus

With the growing demand for high-precision monitoring of crop growth in precision agriculture, the heterogeneity of multimodal remote sensing data and the scarcity of high-quality annotated samples have become key bottlenecks hindering the practical implementation of related technologies. To…

Close-range vocal interaction in the common marmoset ( Callithrix jacchus )

Rogier Landman; Jitendra Sharma; Julia B. Hyman dkk.

PLOS ONE, Vol. 15 No. 4 · 2020 · Inggris · PLOS Scopus

Vocal communication in animals often involves taking turns vocalizing. In humans, turn-taking is a fundamental rule in conversation. Among non-human primates, the common marmoset is known to engage in antiphonal calling using phee calls and trill calls. Calls of the trill type are the most common…

Two eARCHT3.0 Lines for Optogenetic Silencing of Dopaminergic and Serotonergic Neurons

Alexandra Krol; Violeta G. Lopez-Huerta; Taylor E. C. Corey dkk.

Frontiers in Neural Circuits, Vol. 13 · 2019 · Inggris · DOAJ Scopus

Dopaminergic and serotonergic neurons modulate and control processes ranging from reward signaling to regulation of motor outputs. Further, dysfunction of these neurons is involved in both degenerative and psychiatric disorders. Elucidating the roles of these neurons has been greatly facilitated by…

Correction: Dynamic Remodeling of Dendritic Arbors in GABAergic Interneurons of Adult Visual Cortex

Wei-Chung Allen Lee; Hayden Huang; Guoping Feng dkk.

PLoS Biology, Vol. 4 No. 5 · 2006 · Inggris · PLOS Scopus

Chronic in vivo imaging of fluorescent-labeled neurons in adult mice reveals extension and retraction of dendrites in GABAergic non-pyramidal interneurons of the cerebral cortex.

Dynamic Remodeling of Dendritic Arbors in GABAergic Interneurons of Adult Visual Cortex

Wei-Chung Allen Lee; Hayden Huang; Guoping Feng dkk.

PLoS Biology, Vol. 4 No. 2 · 2005 · Inggris · PLOS Scopus

Despite decades of evidence for functional plasticity in the adult brain, the role of structural plasticity in its manifestation remains unclear. To examine the extent of neuronal remodeling that occurs in the brain on a day-to-day basis, we used a multiphoton-based microscopy system for chronic in…

Biophysical modeling of thalamic reticular nucleus subpopulations and their differential contribution to spindle dynamics

Polina Litvak; Nolan D. Hartley; Ryan Kast dkk.

iScience, Vol. 28 No. 9 · 2025 · Inggris · DOAJ Scopus

Summary: Burst firing in thalamic reticular neurons is key to sleep rhythms and is linked to neurodevelopmental disorders. Several models of reticular neurons are currently available; however, a biophysically detailed model reproducing experimental burst firing heterogeneity is lacking. We…

Direct modulation of GFAP-expressing glia in the arcuate nucleus bi-directionally regulates feeding

Naiyan Chen; Hiroki Sugihara; Jinah Kim dkk.

eLife, Vol. 5 · 2016 · Inggris · DOAJ

Multiple hypothalamic neuronal populations that regulate energy balance have been identified. Although hypothalamic glia exist in abundance and form intimate structural connections with neurons, their roles in energy homeostasis are less known. Here we show that selective Ca2+ activation of glia in…

Monoacylglycerol Lipase Is a Therapeutic Target for Alzheimer's Disease

Rongqing Chen; Jian Zhang; Yan Wu dkk.

Cell Reports, Vol. 2 No. 5 · 2012 · Inggris · DOAJ Scopus

Alzheimer's disease (AD) is the most common cause of dementia among older people. There are no effective medications currently available to prevent and treat AD and halt disease progression. Monoacylglycerol lipase (MAGL) is the primary enzyme metabolizing the endocannabinoid 2-arachidonoylglycerol…
