A neuroeconomic theory of bidirectional synaptic plasticity and addiction [PDF]
arXiv, 2011 Neuronal mechanisms underlying addiction have been attracting attention in neurobiology, economics, neuropsychiatry, and neuroeconomics. This paper proposes a possible link between economic theory of addiction (Becker and Murphy, 1988) and neurobiological theory of bidirectional synaptic plasticity (Bienenstock, Cooper, Munro, 1982) based on recent ...

AGAP3 and Arf6 Regulate Trafficking of AMPA Receptors and Synaptic Plasticity
Journal of Neuroscience, 2013 During NMDA receptor-mediated long-term potentiation (LTP), synapses are strengthened by trafficking AMPA receptors to the synapse through a calcium-dependent kinase cascade following activation of NMDA receptors.

Cytotoxicity of 19 Pesticides in Rainbow Trout Gill, Liver, and Intestinal Cell Lines
Environmental Toxicology and Chemistry, EarlyView.Abstract The rainbow trout gill cell line (RTgill‐W1), via test guideline 249 of the Organisation for Economic Co‐operation and Development, has been established as a promising New Approach Methodology, although to advance confidence in the method more case studies are needed that: 1) expand our understanding of applicability domains (chemicals with ...

Detection in Molecular Communications with Ligand Receptors under Molecular Interference [PDF]
arXiv, 2020 Molecular Communications (MC) is a bio-inspired communication technique that uses molecules to transfer information among bio-nano devices. In this paper, we focus on the detection problem for biological MC receivers employing ligand receptors to infer the transmitted messages encoded into the concentration of molecules, i.e., ligands.

Epilepsy Currents, 2013 Commentary The α-amino-3-hydroxy-5-methyl-4-isoxazole propionate (AMPA)-type glutamate receptors (AMPAR) are normally assembled from GluA subunits 1–4 into tetrameric heteromers containing GluA2 within the endoplasmic reticulum.

Glia, EarlyView.Comprehensive analysis of cortical astrocyte gene expression across the lifespan. Profiling dynamic changes of key astrocyte genes reveals functional shifts. Astrocytes contribute to gene‐length‐dependent transcription decline in the aging brain. ABSTRACT Astrocytes are the most abundant glial cell type in the central nervous system (CNS).

Instantons in the working memory: implications for schizophrenia [PDF]
arXiv, 1999 The influence of the synaptic channel properties on the stability of delayed activity maintained by recurrent neural network is studied. The duration of excitatory post-synaptic current (EPSC) is shown to be essential for the global stability of the delayed response.

Intracellular machinery for the transport of AMPA receptors [PDF]
British Journal of Pharmacology, 2008 AMPA‐type glutamate receptors are one of the most dynamic components of excitatory synapses. Their regulated addition and removal from synapses leads to long‐lasting forms of synaptic plasticity, known as long‐term potentiation (LTP) and long‐term depression (LTD).

Neuroscience ResearchNMDA and AMPA receptors are co-localized at most glutamatergic synapses, where their numbers and distribution undergo dynamic changes. Glutamate binds to both the NMDA and AMPA receptors.
