Perineuronal Nets: Plasticity, Protection, and Therapeutic Potential
Trends in Neurosciences, 2019 © 2019 Elsevier Ltd The relationship between neurons and perineuronal nets (PNNs) is attracting attention as a central mechanism controlling brain plasticity.

An Extracellular Perspective on CNS Maturation: Perineuronal Nets and the Control of Plasticity [PDF]
International Journal of Molecular Sciences, 2021 During restricted time windows of postnatal life, called critical periods, neural circuits are highly plastic and are shaped by environmental stimuli. In several mammalian brain areas, from the cerebral cortex to the hippocampus and amygdala, the closure

Neuroscience Letters, 1996 Parvalbumin-immunoreactive interneurons are surrounded by perineuronal nets, containing molecules of the extracellular matrix (e.g. tenascin-R). Furthermore, they seem to have a special cytoskeleton composed of, among others, ankyrinR and beta Rspectrin.

Releasing Addiction Memories Trapped in Perineuronal Nets [PDF]
Trends in Genetics, 2018 Drug addiction can be conceptualized at a basic level as maladaptive learning and memory. Addictive substances elicit changes in brain circuitry involved in reward, cognition, and emotional state, leading to the formation and persistence of strong drug-associated memories that lead to craving and relapse.

The Perineuronal Net: A Weapon for a Challenge
Journal of the History of the Neurosciences, 1999Theories and data do not always fit and sometimes are sources of conflicts among scientists. This is the case of a morphological structure, the perineuronal net, which was denied on the basis of an ideological conflict between two giants of neurosciences: Camillo Golgi and Santiago Ramon y Cajal. The perineuronal net is a reticular structure enveloping

Perineuronal nets in the auditory system
Hearing Research, 2015Perineuronal nets (PNs) are a unique and complex meshwork of specific extracellular matrix molecules that ensheath a subset of neurons in many regions of the central nervous system (CNS). PNs appear late in development and are supposed to restrict synaptic plasticity and to stabilize functional neuronal connections.

Neurocan Contributes to Perineuronal Net Development
Neuroscience, 2020Perineuronal nets (PNs) are matrix molecule assemblies surrounding neuronal somata, dendrites and axon initial segments in a lattice-like appearance. PN molecules are involved in many structural and physiological processes during development and in adulthood, suggesting a crucial role in normal brain function.

Perineuronal nets: past and present
Trends in Neurosciences, 1998Golgi ranked the peripheral reticulum--which adheres intimately to nerve cell surfaces--alongside the intracellular reticulum, or Golgi apparatus,which immortalized his name. At first dismissed as an artefact of capricious staining techniques, this peripheral reticulum, or perineuronal net, is now recognized as a genuine entity in neurocytology.
