Hebb and homeostasis in neuronal plasticity

Current Opinion in Neurobiology, 2000
The positive-feedback nature of Hebbian plasticity can destabilize the properties of neuronal networks. Recent work has demonstrated that this destabilizing influence is counteracted by a number of homeostatic plasticity mechanisms that stabilize neuronal activity.

Postsynaptic actin and neuronal plasticity

Current Opinion in Neurobiology, 1999
In the adult brain, actin is concentrated in dendritic spines where it can produce rapid changes in their shape. Through various synaptic junction proteins, this postsynaptic actin is linked to neurotransmitter receptors, influencing their function and, in turn, being influenced by them.

Neuronal Modulation and Plasticity in Vitro

1994
Publisher Summary This chapter emphasizes on the contribution that in vitro studies that have made in determining the influence of trophic factors and physical environment on neuronal survival and phenotypic plasticity. It also considers the control of neurite extension and growth cone activity in finding pathways and establishing synaptic ...

Microglia in neuronal plasticity: Influence of stress

Neuropharmacology, 2015
The central nervous system (CNS) has previously been regarded as an immune-privileged site with the absence of immune cell responses but this dogma was not entirely true. Microglia are the brain innate immune cells and recent findings indicate that they participate both in CNS disease and infection as well as facilitate normal CNS function.

Plasticity in Dopamine Neurons

2016
Dopamine (DA) neurons in the ventral midbrain can act as a point of convergence for information arriving from various glutamate and GABA afferents. The synaptic inputs from these afferents to midbrain DA neurons undergo various forms of plasticity. Both excitatory and inhibitory afferents can undergo different forms of long-term potentiation (LTP) and ...

A Model of the Plastic Neuron

IEEE Transactions on Military Electronics, 1963
Substantial physiological evidence indicates that neuron thresholds and synaptic weights in living creatures are adjusted by mechanisms quite different from those that have ordinarily been proposed in neural net investigations. This paper presents a theoretical model of the plastic neuron in which threshold and synaptic weights are adjusted solely on ...

Mitochondrial Regulation of Neuronal Plasticity

Neurochemical Research, 2006
The structure and function of neurons is dynamic during development and in adaptive responses of the adult nervous system to environmental demands. The mechanisms that regulate neuronal plasticity are poorly understood, but are believed to involve neurotransmitter and neurotrophic factor signaling pathways.
