One major factor for cochlear neurons pathology is excitotoxicity. This is due to an excess release of glutamate, the IHC neurotransmitter.

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. Towards this end, the glutamatergic agent ketamine has been intensely investigated over the past 2 decades. By inhibiting glycogen degradation in co-cultures it was evident that glycogen provides energy to sustain glutamatergic neurotransmission, i.e. release and uptake of glutamate.

Furthermore, these data imply that enhanced D 4 receptor–mediated Glutamatergic neurotransmission in thalamocortical system may play an important role in modulating sensory perception and consciousness. Our results showed that ketamine (30 μM–1000 μM) decreased the amplitude of sEPSCs and higher concentration of ketamine (300 μM and 1000 μM) decreased the frequency of sEPSCs. VMH glutamatergic neurotransmission has been shown to be important for enhancing counterregulatory responses to hypoglycemia . However, the postsynaptic receptors that mediate these stimulatory effects and how RH affects glutamate neurotransmission have not been investigated in detail.

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. Drugs acting on the excitatory glutamatergic system have so far not been tested with TMS-EEG measures, although glutamatergic neurotransmission plays a fundamental role in the excitation Glutamatergic neurotransmission: due to the risk of excitotoxic damage in the wake of excessive glutamatergic stimulation, precise physiological control of glutamate must be maintained in the mammalian CNS. Glutamine (Gln) is converted to glutamate (Glu) by glutaminase [though glutamate may also be derived from the TCA cycle (not shown)]. Overview of Synaptic Neurotransmission: Glutamatergic Excitation Glutamate receptors (GluRs), the major excitatory receptor in the brain, are characterized as ionotropic or metabotropic. Ionotropic GluRs are tetrameric ligand-gated cation channels that induce depolarization of the postsynaptic membrane following the presynaptic release of glutamate. Although most techniques today indirectly measure glutamatergic neurotransmission in vivo, accumulating evidence has revealed that glutamatergic dysfunction plays a crucial role in major psychiatric disorders, such as schizophrenia, BD, and MDD (including TRD). Ketamine, esketamine, and many other pharmacological compounds targeting the glutamate system are available for human trials of major psychiatric disorders. In neuroscience, glutamate refers to the anion of glutamic acid in its role as a neurotransmitter: a chemical that nerve cells use to send signals to other cells.

Glutamate mediates essentially all rapid excitatory signaling in the mammalian CNS. This excitatory signaling is counterbalanced by GABA- or glycine-mediated inhibition. 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. 2012-02-01 · The tight control of glutamatergic neurotransmission is an energy-costly process, requiring multiple regulatory processes and high levels of glucose and oxygen consumption. Like all amino acids, glutamate has a C-terminus and an N-terminus; the C-terminus and carbon backbone derived from glucose. 1998-10-15 · Glutamatergic neurotransmission involves structural and clinical deficits of schizophrenia. Tsai G(1), van Kammen DP, Chen S, Kelley ME, Grier A, Coyle JT. Author information: (1)Laboratory of Molecular and Developmental Neuroscience, Harvard Medical School, Charlestown, Massachusetts, USA. 2021-04-14 · Neuronal activity in the brain reflects an excitation–inhibition balance that is regulated predominantly by glutamatergic and GABAergic neurotransmission, and often disturbed in neuropsychiatric Overview of Synaptic Neurotransmission: Glutamatergic Excitation Glutamate receptors (GluRs), the major excitatory receptor in the brain, are characterized as ionotropic or metabotropic. Ionotropic GluRs are tetrameric ligand-gated cation channels that induce depolarization of the postsynaptic membrane following the presynaptic release of glutamate.

It is by a wide margin the most abundant excitatory neurotransmitter in the vertebrate nervous system.
