Neuroprotection, excitotoxicicity and nmda antagonists [PDF]

Arquivos de Neuro-Psiquiatria, 2000
PURPOSE: To analyze the main aspects of neuroprotection and excitotoxicity. DISCUSSION: This is a significant theory on the pathophysiology of cerebral ischemia; it is based on the release of excitatory aminoacid (EAA), mainly glutamate. The sequence starts with a decrease of the blood flow and ends in neuronal death.

Dynamin-dependent NMDAR endocytosis during LTD and its dependence on synaptic state

BMC Neuroscience, 2005
Background The N-methyl-D-aspartate (NMDA)-type glutamate receptor expressed at excitatory glutamatergic synapses is required for learning and memory and is critical for normal brain function.

Subanesthetic ketamine treatment promotes abnormal interactions between neural subsystems and alters the properties of functional brain networks [PDF]

, 2014
Acute treatment with subanesthetic ketamine, a non-competitive N-methyl-D-aspartic acid (NMDA) receptor antagonist, is widely utilized as a translational model for schizophrenia. However, how acute NMDA receptor blockade impacts on brain functioning at a

Effect of acetaminophen use on GABA, NMDA, and synaptic plasticity-related genes in the immature mouse brain: A preliminary study

The EuroBiotech Journal
Background/aim: Acetaminophen is frequently used as an analgesic during pregnancy. The purpose of the present study was to evaluate the effects of acetaminophen administered to pregnant mice on the fetal brain, attention, memory, and learning functions ...

Slowly developing depression of N-methyl-D-aspartate receptor mediated responses in young rat hippocampi

BMC Neuroscience, 2004
Background Activation of N-methyl-D-aspartate (NMDA) type glutamate receptors is essential in triggering various forms of synaptic plasticity. A critical issue is to what extent such plasticity involves persistent changes of glutamate receptor subtypes ...

Glutamate-N-methyl-D-aspartate receptor modulation and minocycline for the treatment of patients with schizophrenia: an update

Brazilian Journal of Medical and Biological Research, 2009
Growing consistent evidence indicates that hypofunction of N-methyl-D-aspartate (NMDA) transmission plays a pivotal role in the neuropathophysiology of schizophrenia.

Exploiting the molecular diversity of the synapse to investigate neuronal communication: A guide through the current toolkit

European Journal of Neuroscience, Volume 56, Issue 12, Page 6141-6161, December 2022., 2022
Chemical synapses are tiny and overcrowded environments enriched with thousands of protein species. Many efforts have been devoted to developing sensors and actuators able to evaluate and control synaptic communication. Most of these recent tools are based on the engineering of one or more specific synaptic proteins used to target active moieties to ...

Biased Random-Walk Learning: A Neurobiological Correlate to Trial-and-Error [PDF]

arXiv, 1993
Neural network models offer a theoretical testbed for the study of learning at the cellular level. The only experimentally verified learning rule, Hebb's rule, is extremely limited in its ability to train networks to perform complex tasks. An identified cellular mechanism responsible for Hebbian-type long-term potentiation, the NMDA receptor, is highly

A head start: The relationship of placental factors to craniofacial and brain development

Developmental Dynamics, EarlyView.
Abstract In recent years, the importance of placental function for fetal neurodevelopment has become increasingly studied. This field, known as neuroplacentology, has greatly expanded possible etiologies of neurodevelopmental disorders by exploring the influence of placental function on brain development.

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.
