Artificial intelligence–based 3D segmentation of tangle‐associated TDP‐43 in neurodegeneration

Brain Pathology, EarlyView.
Multiplex immunostaining of anti‐phosphorylated TDP‐43, tau (AT8, pS396, TauC3, MN423, GT38), and Thioflavin S combined with AI‐based object recognition, reconstruction, and TAT maturation analysis pipeline in limbic regions revealed that distinct aggregation and tangle maturation patterns underscored region‐specific dynamics in the neurodegenerative ...

What makes a lonely child: environmental, health, and multimodal neuroimaging correlates of prospective loneliness in the ABCD study

Journal of Child Psychology and Psychiatry, EarlyView.
Background Loneliness in childhood is a growing public health concern, yet early multilevel candidate risk and protective factors remain insufficiently mapped. Systematic investigation is essential to guide prevention and intervention during sensitive developmental periods.

Independent delta/theta rhythms in the human hippocampus and entorhinal cortex

Frontiers in Human Neuroscience, 2008
Theta oscillations in the medial temporal lobe (MTL) of mammals are involved in various functions such as spatial navigation, sensorimotor integration, and cognitive processing.

Orchestrated molecular changes of proliferative, migratory‐fibrillar, synaptic, and postmigratory compartments align with precocious cortex‐type specification in the early human pallium

Journal of Anatomy, EarlyView.
Early human cortical development is organized by transient cellular compartments that define cortical types before mature layers form. Analysis of the human fetal pallium (7.5–15 PCW) shows distinct spatiotemporal trajectories for the archicortex, mesocortex, and neocortex, with delayed but accelerated differentiation in allocortical regions.

From senescence and inflammaging to systemic comorbidities: Drivers of aging‐associated periodontitis

Periodontology 2000, EarlyView.
Abstract Background Aging is accompanied by a chronic low‐grade inflammatory process, known as inflammaging, as well as immunosenescence, an age‐related decline and dysregulation of immune function, and cellular senescence, a process in which cells enter a state of irreversible growth arrest while actively releasing pro‐inflammatory factors.

Parvalbumin interneurons in Alzheimer's disease: Physiological insights and pathophysiological mechanisms

Journal of Cell Communication and Signaling, Volume 20, Issue 3, September 2026.
Physiological and Pathological Alterations in PV+ Neurons: Under physiological conditions, PV+ interneurons exhibit fast‐spiking properties and generate gamma oscillations at the cost of high energy consumption. In AD, PV+ neurons display abnormalities in ion channels, dendrites, neurotransmission, energy metabolism, and neural oscillations, ultimately

Interactions between stimulus and response types are more strongly represented in the entorhinal cortex than in its upstream regions in rats

eLife, 2017
Previously we reported results which suggested that response types are critical in dissociating the lateral entorhinal cortex (LEC) from the medial entorhinal cortex (MEC) in a scene memory task (Yoo and Lee, 2017).

Young Adult Microglial Deletion of C1q Reduces Engulfment of Synapses and Partially Mitigates Cognitive Impairment in an Aggressive Alzheimer's Disease Mouse Model

Glia, Volume 74, Issue 9, September 2026.
Young adult deletion of microglial C1q reduced engulfment of Vglut1+ synapses and mitigated spatial cognitive deficits at 10 months of age in the amyloidopathy Arctic mouse model of AD. Neither fibrillar amyloid plaques nor soluble or insoluble Aβ levels in the hippocampus were affected by young adult microglial loss of C1q despite reduced phagocytosis

Optogenetic dissection of ictal propagation in the hippocampal–entorhinal cortex structures

Nature Communications, 2016
The network mechanism supporting seizure spread in temporal lobe epilepsy (TLE) is only partially understood. Using optogenetic methods, Lu et al.identify a feed-forward propagation pathway of ictal discharges from the dentate gyrus/hilus to the medial ...

An Update on the Model of Connectivity of the Hippocampal Formation (I): The Perforant Pathway to the Dentate Gyrus

Hippocampus, Volume 36, Issue 5, September 2026.
ABSTRACT The hippocampus participates in crucial functions such as memory consolidation, spatial processing and emotional regulation that require diverse input from multiple cortical areas that is funneled through the upper layers of the entorhinal cortex (EC), mostly from layer II to the dentate gyrus (DG).
