Energy efficient synaptic plasticity [PDF]

eLife, 2019
Many aspects of the brain’s design can be understood as the result of evolutionary drive toward metabolic efficiency. In addition to the energetic costs of neural computation and transmission, experimental evidence indicates that synaptic plasticity is metabolically demanding as well. As synaptic plasticity is crucial for learning, we examine how these

Novelty producing synaptic plasticity [PDF]

Proceedings of the 2020 Genetic and Evolutionary Computation Conference Companion, 2020
A learning process with the plasticity property often requires reinforcement signals to guide the process. However, in some tasks (e.g. maze-navigation), it is very difficult (or impossible) to measure the performance of an agent (i.e. a fitness value) to provide reinforcements since the position of the goal is not known.

Gravin orchestrates protein kinase A and 2-adrenergic receptor signaling critical for synaptic plasticity and memory [PDF]

, 2012
A kinase-anchoring proteins (AKAPs) organize compartmentalized pools of protein kinase A (PKA) to enable localized signaling events within neurons. However, it is unclear which of the many expressed AKAPs in neurons target PKA to signaling complexes ...

The malleable brain: plasticity of neural circuits and behavior: A review from students to students [PDF]

, 2017
One of the most intriguing features of the brain is its ability to be malleable, allowing it to adapt continually to changes in the environment. Specific neuronal activity patterns drive long-lasting increases or decreases in the strength of synaptic ...

Synaptic plasticity in schizophrenia pathophysiology

IBRO Neuroscience Reports, 2023
Schizophrenia is a severe neuropsychiatric syndrome with psychotic behavioral abnormalities and marked cognitive deficits. It is widely accepted that genetic and environmental factors contribute to the onset of schizophrenia. However, the etiology and pathology of the disease remain largely unexplored.

Synaptic Plasticity and the Warburg Effect [PDF]

Cell Metabolism, 2014
Functional brain imaging studies show that in certain brain regions glucose utilization exceeds oxygen consumption, indicating the predominance of aerobic glycolysis. In this issue, Goyal et al. (2014) report that this metabolic profile is associated with an enrichment in the expression of genes involved in synaptic plasticity and remodeling processes.

Alterations in brain connectivity due to plasticity and synaptic delay

, 2017
Brain plasticity refers to brain's ability to change neuronal connections, as a result of environmental stimuli, new experiences, or damage. In this work, we study the effects of the synaptic delay on both the coupling strengths and synchronisation in a ...

Synaptic plasticity and phosphorylation [PDF]

Pharmacology & Therapeutics, 2006
A number of neuronal functions, including synaptic plasticity, depend on proper regulation of synaptic proteins, many of which can be rapidly regulated by phosphorylation. Neuronal activity controls the function of these synaptic proteins by exquisitely regulating the balance of various protein kinase and protein phosphatase activity.

Glial Cells and Synaptic Plasticity [PDF]

Neural Plasticity, 2016
Neuroglia are composed of highly heterogeneous cellular populations of neural (astrocytes, oligodendrocytes, and NG2 glial cells) and nonneural (microglia) origin that are essential for maintaining efficient neurotransmission, homeostatic cascades, supply of energy metabolites, turnover of neurotransmitters, and establishment of the blood-brain barrier

A Mathematical Model of Tripartite Synapse: Astrocyte Induced Synaptic Plasticity

, 2012
In this paper we present a biologically detailed mathematical model of tripartite synapses, where astrocytes modulate short-term synaptic plasticity. The model consists of a pre-synaptic bouton, a post-synaptic dendritic spine-head, a synaptic cleft and ...
