This volume presents techniques and recent developments in biochemical approaches to study glutamatergic neurotransmission. This book contains detailed discussions on tracing neuronal pathways, functional or spectroscopic imaging, optogenetic or pharmacological tools, and extracellular neurochemistry in experimental clinical models.

It also serves as the primary neurotransmitter for some localized brain regio At the neurochemical level, the dopaminergic modulation of glutamatergic cortico-striatal afferents, innervating distinct populations of striatonigral and striatopallidal medium-sized spiny neurons, is essential for the regulation of thalamo-cortical output to maintain the spatial selectivity of context-adapted behaviour (Grace et al., 2007). Glutamatergic neurotransmission In glutamatergic neurons, glutamate is packaged into synaptic vesicles (SVs) by vesicular glutamate transporters (VGLUT1–3) [ 26 ]. The loaded SVs then dock near the release site, where they are primed into a state of competence for Ca 2+ -triggered fusion-pore opening. The present findings demonstrate that ketamine and PCP may exert at least part of their effect in the PFC by activationof glutamatergic neurotransmission at AMPA/kainate receptors. This is supported by findings that subanesthetic doses of ketamine increase Glu efflux and that AMPA/kainate receptor antagonists attenuate ketamine-induced PFC dopamine release and cognitive impairment. Alterations in glutamatergic neurotransmission are thought to contribute to schizophrenia, a neuropsychiatric disease with multifactorial causes.

1) is the major excitatory amino acid neurotransmitter in the CNS and a possible role has also been recently suggested in the peripheral nervous.

This book contains detailed discussions on tracing neuronal pathways, functional or spectroscopic imaging, optogenetic or pharmacological tools, and extracellular neurochemistry in experimental clinical models. This study provided that the evidence for an association between GRM3 genotype and schizophrenia and suggest a role for glutamate neurotransmission in the establishment and maintenance of myelinated fibers.

Effects of Age and Acute Ethanol on Glutamatergic Neurotransmission in the Medial injection (1 g/kg) on cortical glutamate levels in adolescent and adult rats. Restricted cortical and amygdaloid removal of vesicular glutamate transporter 2 induced late-onset, chronic reduction of glutamatergic neurotransmission and The general glutamate hypothesis of schizophrenia suggests a relationship between an aberrant glutamatergic neurotransmission in brain and cognitive deficits Glutamate is the main excitatory neurotransmitter in the brain.

Alzheimer’s disease (AD) is an age-related dementia and neurodegenerative disorder, characterized by Aβ and tau protein deposition impairing learning, memory and suppressing synaptic plasticity of neurons. Increasing evidence suggests that there is a link between the glucose and glutamate alterations with age that down-regulates glucose utilization reducing glutamate levels in AD

are mediated via alterations of glutamate receptor-mediated neurotransmission.

Evidence indicates abnormalities of glutamatergic neurotransmission or glutamatergic dysfunction as playing an important role in the development of many major psychiatric disorders (e.g., schizophrenia, bipolar disorder, and major depressive disorder). Moghaddam, B., Adams, B., Verma, A. et al (1997) Activation of glutamatergic neurotransmission by ketamine: a novel step in the pathway from NMDA receptor blockade to dopaminergic and cognitive disruptions associated with the prefrontal cortex. Journal of Neuroscience, 17, 2921 – 2927.CrossRef Google Scholar PubMed 2017-02-14 · Genetic inhibition of neurotransmission reveals role of glutamatergic input to dopamine neurons in high-effort behavior Glutamate is the neurotransmitter in most of the excitatory synapses and appears to be involved in functions such as motor behaviour, cognition and emotion, which alter with age. However, relatively few studies have been conducted to study the relationship between glutamate and aging of the brain. Reversible suppression of glutamatergic neurotransmission thus can be manipulated with spatiotemporal accuracy by DOX treatment and removal. These transgenic mice will serve as an animal model to study the cerebellar function in motor coordination and learning. In this context, emerging preclinical and clinical evidence of the impaired relationship between glutamatergic neurotransmission and synaptic plasticity in mood disorders has guided the search for novel pharmacotherapeutic strategies.

2001-01-01 · Glutamatergic neurotransmission may be altered at several different steps: the content (expression, synthesis and/or degradation) of the main proteins involved in glutamatergic neurotransmission (e.g. the different types of glutamate receptors or transporters); the regulation of the spatial location of the receptors and transporters; the function of the receptors and transporters, which is A thorough dose-response study using microdialysis in conscious rats indicated that low doses of ketamine (10, 20, and 30 mg/kg) increase glutamate outflow in the PFC, suggesting that at these doses ketamine may increase glutamatergic neurotransmission in the PFC at non-NMDA glutamate receptors. As the static concentration of Glu measured by MRS reflects the total Glu pool size, which is involved in varied functions (e.g. oxidative metabolism, neurotransmission), caution is often required when attributing changes in Glu or the composite Glx signal to the integrity of glutamatergic neurotransmission . Whether glutamatergic neurotransmission and oxidative stress are enhanced during ethanol withdrawal in humans is unknown.

While the traditional monoaminergic hypothesis has largely fallen short in its ability to provide a complete picture of major depressive disorder, emerging preclinical and clinical findings suggest that dysfunctional glutamatergic neurotransmission may underlie the pathophysiology of both major depressive disorder and bipolar depression. The neurotransmission mediated by the excitatory amino acids (EAA) glutamate (GLU) and aspartate is of interest to the pharmacotherapy of psychosis due to its role in neurodevelopment and neurotoxicity, its complex interactions with dopaminergic and other neurotransmitter systems and its pivotal importance in recent models of schizophrenia.
