It plays a critical role in fundamental processes, such as learning, cognition, and memory, and dysregulation of glutamatergic transmission can result in several neurological conditions. A "BASIC" explanation of how a Glutamatergic synapse works. This is a starter video mean to build a foundation for Glutamatergic receptor theory, Glutamaterg Glutamate is the major excitatory neurotransmitter in the mammalian central nervous system (CNS). Glutamate is packaged into synaptic vesicles in the presynaptic terminal. Once released into the synaptic cleft, glutamate acts on postsynaptic ionotropic glutamate receptors (iGluRs) to mediate fast excitatory synaptic transmission. We developed a synthetic, structure-guided, synaptic organizer termed CPTX, which induced functional and structural excitatory synapses in the cerebellar, hippocampal, and spinal cord neuronal circuits in vivo. Molecular components involved in excitatory synapses are considerably different among neuronal circuits.

Glutamatergic excitotoxicity may also induce long-term changes in basal and activity-dependent IEG expression following such an insult (Barker-Haliski et al. 2012). Collectively, these effects on IEG expression likely contribute to further modification of synaptic transmission in epilepsy ( Ortuno-Sahagun et al. 2013 ). To investigate whether the rapid stress‐induced response of the glutamatergic synapse was influenced by a previous history of cocaine, rats were exposed to repeated cocaine injections during adolescence [from postnatal day (PND) 28–42], subjected to a single swim stress (5 minutes) three days later (PND 45) and sacrificed 15 minutes after the end of this stressor. 2021-04-06 · Metabotropic glutamate receptors (mGluRs) are G protein–coupled receptors that regulate various aspects of central nervous system processing in normal physiology and in disease. They are thought to Glutamate is the main excitatory transmitter in the mammalian CNS, mediating fast synaptic transmission primarily by activation of AMPA-type glutamate receptor channels.

Glutamatergic synapse is involved in regulating the establishment of neural network connections during the brain and spinal cord development and mediating the cellular processes pivotal for synaptic transmission and plasticity. The correct functioning of glutamatergic synapses is essential for learning and memory. Glutamate is the major excitatory neurotransmitter at almost all synapses in the vertebrate central nervous system (CNS).

Glutamatergic synapse

Glutamatergic synapses are the main excitatory synapses in the brain. These synapses consist of glutamate localized inside presynaptic vesicles and glutamate receptors on the postsynaptic membrane.

The first glutamatergic transmission is mediated only by N -methyl-D-aspartate (NMDA) receptors and is silent at resting potentials. More mature synapses acquire transmission by α-amino-3-hydroxy-5-methyl-4-isoxazole propionic acid (AMPA) receptors.
