The Perineuronal ‘Safety’ Net? Perineuronal Net Abnormalities in Neurological Disorders
Frontiers in Molecular Neuroscience, 2018 Perineuronal nets (PNN) are extracellular matrix (ECM) assemblies that preferentially ensheath parvalbumin (PV) expressing interneurons. Converging evidence indicates that PV cells and PNN are impaired in a variety of neurological disorders.

Simulating Effects of Learning and Lesions with a Model of Intrinsic and Synaptically Gated Responses of Striatal Cholinergic Interneurons [PDF]
, 2006 The giant cholinergic interneurons of the striatum are tonically active neurons (TANs) that respond with characteristic pauses to novel events and to appetitive and aversive conditioned stimuli.

Dopamine-modulated dynamic cell assemblies generated by the GABAergic striatal microcircuit [PDF]
, 2009 The striatum, the principal input structure of the basal ganglia, is crucial to both motor control and learning. It receives convergent input from all over the neocortex, hippocampal formation, amygdala and thalamus, and is the primary recipient of ...

Fear Learning Regulates Cortical Sensory Representations by Suppressing Habituation
Frontiers in Neural Circuits, 2018 Projections from auditory cortex to the amygdala are thought to contribute to the induction of auditory fear learning. In addition, fear conditioning has been found to enhance cortical responses to conditioned tones, suggesting that cortical plasticity ...

The Auditory System of the Dipteran Parasitoid Emblemasoma auditrix (Sarcophagidae) [PDF]
, 2016 Several taxa of insects evolved a tympanate ear at different body positions, whereby the ear is composed of common parts: a scolopidial sense organ, a tracheal air space, and a tympanal membrane. Here, we analyzed the anatomy and physiology of the ear at

Advanced Healthcare Materials, EarlyView.This review summarizes the roles of key central nervous system cell types, the extracellular matrix, and the blood‐brain barrier in neuroinflammation, and their integration into diverse 3D culture systems. It examines major incorporation strategies, including direct co‐culture, hydrogel encapsulation, transwell migration assays, and bioprinting ...

The gamma rhythm as a guardian of brain health
eLifeGamma oscillations in brain activity (30–150 Hz) have been studied for over 80 years. Although in the past three decades significant progress has been made to try to understand their functional role, a definitive answer regarding their causal implication

Dysmaturation of Somatostatin Interneurons Following Umbilical Cord Occlusion in Preterm Fetal Sheep
Frontiers in Physiology, 2019 IntroductionCerebral white matter injury is the most common neuropathology observed in preterm infants. However, there is increasing evidence that gray matter development also contributes to neurodevelopmental abnormalities.

Neuroanatomical Alterations in the CNTNAP2 Mouse Model of Autism Spectrum Disorder
Brain Sciences, 2023 Autism spectrum disorder (ASD) is associated with neurodevelopmental alterations, including atypical forebrain cellular organization. Mutations in several ASD-related genes often result in cerebral cortical anomalies, such as the abnormal developmental ...
