Perineuronal nets: Cruise from a honeycomb to the safety nets

open access: yesBrain Research Bulletin, 2022
The extracellular matrix (ECM) is a significant component of the brain, constituting up to 20 % of the brain volume and perform multifarious functions during development, maturation and regeneration of the central nervous system (CNS). ECM molecules assemble systematically to form a relatively rigid and unique lattice-like structure, known as ...

Diverse functions of perineuronal nets

open access: yesActa Neurobiologiae Experimentalis, 2009
Perineuronal nets represent well-organised components of the extracellular matrix, which are surrounding cell bodies, dendrites, and axon segments of a particular class of neurones as well as forming lattice-like structures. The role of perineuronal nets is not fully elucidated yet.

Longitudinal in vivo imaging of perineuronal nets

open access: yesNeurophotonics, 2023
Perineuronal nets (PNNs) are extracellular matrix structures implicated in learning, memory, information processing, synaptic plasticity, and neuroprotection. However, our understanding of mechanisms governing the evidently important contribution of PNNs to central nervous system function is lacking.

Environmental Enrichment From Birth Impacts Parvalbumin Expressing Cells and Wisteria Floribunda Agglutinin Labelled Peri-Neuronal Nets Within the Developing Murine Striatum

open access: yesFrontiers in Neuroanatomy, 2019
Environmental enrichment can dramatically affect both the development and function of neural circuits. This is accomplished, at least in part, by the regulation of inhibitory cellular networks and related extracellular matrix glycoprotein structures ...

Perineuronal nets in memory processing and behavior

open access: yes, 2020
This doctoral thesis entails work on learning and memory with the goal of understanding mechanisms that regulate plasticity and affect memory processing.

Calretinin as a marker for premotor neurons involved in upgaze in human brainstem

open access: yesFrontiers in Neuroanatomy, 2015
Eye movements are generated by different premotor pathways. Damage to them can cause specific deficits of eye movements, such as saccades. For correlative clinico-anatomical post-mortem studies of cases with eye movement disorders it is essential to ...

Distribution and postnatal development of chondroitin sulfate proteoglycans in the perineuronal nets of cholinergic motoneurons innervating extraocular muscles

open access: yesScientific Reports, 2022
Fine control of extraocular muscle fibers derives from two subpopulations of cholinergic motoneurons in the oculomotor-, trochlear- and abducens nuclei.

Otx2-PNN Interaction to Regulate Cortical Plasticity

open access: yesNeural Plasticity, 2016
The ability of the environment to shape cortical function is at its highest during critical periods of postnatal development. In the visual cortex, critical period onset is triggered by the maturation of parvalbumin inhibitory interneurons, which ...

Cortical reorganization during adolescence: What the rat can tell us about the cellular basis

open access: yesDevelopmental Cognitive Neuroscience, 2020
The human cortex, particularly the prefrontal cortex, decreases in volume during adolescence which indicates considerable pruning. There is consistent evidence from human, monkey and rat tissue that synapses, dendritic spines and dendrites are pruned ...

Neurogenesis mediated plasticity is associated with reduced neuronal activity in CA1 during context fear memory retrieval

open access: yesScientific Reports, 2022
Postnatal hippocampal neurogenesis has been demonstrated to affect learning and memory in numerous ways. Several studies have now demonstrated that increased neurogenesis can induce forgetting of memories acquired prior to the manipulation of ...
