Infralimbic parvalbumin neural activity facilitates cued threat avoidance

open access: yeseLife
The infralimbic cortex (IL) is essential for flexible behavioral responses to threatening environmental events. Reactive behaviors such as freezing or flight are adaptive in some contexts, but in others a strategic avoidance behavior may be more ...

Tonotopically distinct OFF responses arise in the mouse auditory midbrain following sideband suppression

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Sounds of different frequencies elicit spatially distinct patterns of neural activity within the inferior colliculus aligned to the tonotopic organization of afferent projections. Sound‐evoked neural responses can be visualized in awake mice that express fluorescent Ca2+ sensors.

Characterization of postnatal brain injury and behavioural deficits in a rat model of placental insufficiency‐induced fetal growth restriction

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Fetal growth restriction (FGR) is a common pregnancy complication associated with long‐term neurodevelopmental impairments. Using the reduced uterine perfusion pressure (RUPP) rat model of placental insufficiency‐induced FGR, this study demonstrates that FGR leads to persistent anatomical, histological and behavioural ...

Peripheral regeneration of Aβ low‐threshold mechanoreceptors is limited despite activation of regenerative transcriptional pathways

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend The regeneration of Aβ low‐threshold mechanoreceptors (Aβ‐LTMRs), sensory neurons responsible for discriminative touch, has not previously been explored. Here, we took advantage of the selective expression of Calb1 in Aβ‐LTMRs to generate two genetic mouse models for studying their regenerative response after nerve injury.

The Astrocyte Clock Controls Circadian Perineuronal Net Remodeling, Synapse Strength and Learning Behavior

open access: yesGlia, Volume 74, Issue 10, October 2026.
Bmal1 regulates astrocyte extracellular matrix (ECM) gene expression. Bmal1 deletion in astrocytes disrupts normal circadian rhythms in perineuronal nets (PNN) and reduces PNN content in the hippocampus. In parallel with loss of PNNs, deletion of the core circadian clock gene Bmal1 in astrocytes alters behavior and synaptic function in vivo.

Parvalbumin interneuron deficits in schizophrenia

open access: yesEuropean Neuropsychopharmacology
Parvalbumin-expressing (PV+) interneurons represent one of the most abundant subclasses of cortical interneurons. Owing to their specific electrophysiological and synaptic properties, PV+ interneurons are essential for gating and pacing the activity of excitatory neurons.

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

open access: yesJournal 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

The Role of Hippocampal Interneuron Migration in Neurodevelopmental Disorders: A Systematic Review

open access: yesHippocampus, Volume 36, Issue 5, September 2026.
ABSTRACT Hippocampal abnormalities are frequently associated with neurodevelopmental disorders as interneurons are crucial in establishing the network connectivity of neurons. This systematic review analyzed primary literature with a focus on aberrant hippocampal interneuron migration as an etiology for neurodevelopmental disorders, summarizing the ...

miR155, triplicated in Down syndrome, regulates the development of neural stem cells and GABAergic interneurons in Alzheimer's disease mouse and human iPSC models

open access: yesAlzheimer's &Dementia, Volume 22, Issue 8, August 2026.
Abstract INTRODUCTION Dysfunctional microRNAs and GABAergic interneurons are features of Alzheimer's disease (AD). The role of neuronal microRNA155 (miR155), elevated in both AD and Down syndrome (DS), remains unknown. METHODS We utilized in silico analyses of published databases, MIR155‐deleted and ‐overexpressing human induced pluripotent stem cell ...

Regional Functional Molecular Profiles Within the Mammalian Cortex: A Commentary on Limbic Mesocortex

open access: yesJournal of Comparative Neurology, Volume 534, Issue 8, August 2026.
Two lateral mouse brain sagittal sections labeled, respectively, for Lypd1 (A) and Kcnab3 (B). (A) Lypd1 labels positively cortical Layers 2 and 5 (less heavily), but only at limbic mesocortical sites, forming the limbic ring that separates the unlabeled isocortex (IsoCx) from the unlabeled hippocampal and olfactory allocortex (Hi, Sub, ERh; OlfCx ...
