A Brain‐Wide Atlas of Astrocytic Oxytocin Receptors Reveals a Glial Basis for Nucleus Accumbens Modulation of Affiliative Behavior

Advanced Science, EarlyView.
The cellular actors of oxytocin signaling are under intense scrutiny. A brain‐wide anatomical and functional analysis in mice and rats reveals widespread expression of oxytocin receptors in astrocytes. These receptors are functionally active and, in the nucleus accumbens, selectively regulate male social affiliation.

A Model of Neuronal Intrinsic Plasticity

IEEE Transactions on Autonomous Mental Development, 2011
Recent experimental results have accumulated evidence that the neurons can change their response characteristics to adapt to the variations of the synaptic inputs, which is the so-called neuronal intrinsic plasticity mechanism. In this paper, we present a new model on neuronal intrinsic plasticity. We first show that the probability distribution of the

Plasticity of neuronal receptors

The FASEB Journal, 1989
This article describes ways in which receptors, key components of signal propagation through a synapse, can mediate changes in that propagation. Changes occur at four levels: in the signal‐transducing capability of a single receptor molecule, in the number of receptors per cell, in the subcellular placement of receptor molecules ...

Adenosine and neuronal plasticity

Life Sciences, 1996
Adenosine is considered an important neuromodulator of the nervous system acting at pre-, post- and non-synaptic levels. In the present review we describe how adenosine modifies paired-pulse facilitation (PPF), posttetanic depression (PTD), long-term potentiation (LTP), long-term depression (LTD) and depotentiation at the hippocampus, and therefore how

Brain Aging and Neuronal Plasticity^a

Annals of the New York Academy of Sciences, 1992
In the present paper three aspects of the aging processes and their physiopathological implications will be presented: neuronal death, the information handling capabilityof neurons, and the processes of interneuronal communication.

Neurotrophins and Neuronal Plasticity

Science, 1995
There is increasing evidence that neurotrophins (NTs) are involved in processes of neuronal plasticity besides their well-established actions in regulating the survival, differentiation, and maintenance of functions of specific populations of neurons.

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.

Psychomotor stimulants and neuronal plasticity

Neuropharmacology, 2004
Considerable evidence suggests that neuroadaptations leading to addiction involve the same glutamate-dependent cellular mechanisms that enable learning and memory. Long-term potentiation (LTP) and long-term depression (LTD) have therefore become an important focus of addiction research. This article reviews: (1) basic mechanisms underlying LTP and LTD,
