Perineuronal net expression in the brain of a hibernating mammal

Brain Structure and Function, 2019
During hibernation, mammals like the 13-lined ground squirrel cycle between physiological extremes. Most of the hibernation season is spent in bouts of torpor, where body temperature, heart rate, and cerebral blood flow are all very low. However, the ground squirrels periodically enter into interbout arousals (IBAs), where physiological parameters ...

Extracellular matrix and perineuronal nets in CNS repair

Developmental Neurobiology, 2011
AbstractA perineuronal net (PNN) is a layer of lattice‐like matrix which enwraps the surface of the soma and dendrites, and in some cases the axon initial segments, in sub‐populations of neurons in the central nervous system (CNS). First reported by Camillo Golgimore than a century ago, the molecular structure and the potential role of this matrix have

Perineuronal Nets Protect Fear Memories from Erasure

Science, 2009
Adult Fears Why are fear memories almost impossible to get rid of—even with extensive extinction training? Animal studies have shown that the efficacy of extinction learning depends on age. Fear memories in young animals can be permanently erased, but in adults they can be easily recovered after extinction ...

Distribution of perineuronal nets in the adult rat neocortex

Somatosensory & Motor Research
Perineuronal nets (PNNs) are specialised extracellular matrix structures of the central nervous system that predominantly surround inhibitory interneurons. The development of PNNs is activity dependent and relies on sensory input to mature to an adult expression pattern, coinciding with the crysallization of synaptic circuitry following the closure of ...

Perineuronal Nets: From Structure to Neurological Disorders

Current Medicinal Chemistry
Perineuronal nets (PNN) is condensed extracellular matrix (ECM) in the central nervous system (CNS), which surrounds cell soma, axon initial segments, and synapses. In the brain, most neurons surrounded by PNN are interneurons, especially the parvalbumin-expressing interneurons (PVI).

Perineuronal Nets in the Superior Olivary Complex

2018
Abstract This chapter addresses perineuronal nets in the superior olivary complex, a collection of nuclei in the auditory brainstem that are involved in the processing of sound source location. Perineuronal nets, a specific form of extracellular matrix, are believed to control synaptic plasticity.

2.26 - Perineuronal nets in memory

Perineuronal nets (PNN) are specialized structures surrounding certain nerve cells. Although considered as a part of the extracellular matrix (ECM), they are composed of sugars stemming from the cells they surround as well as of extracellular glycoproteins.
