During synaptic transmission
Web2 days ago · Pre- and postsynaptic forms of long-term potentiation (LTP) are candidate synaptic mechanisms underlying learning and memory. At layer 5 pyramidal neurons LTP increases the initial synaptic strength but also short-term depression during high-frequency transmission. This classical form of presynaptic LTP has been referred to as … WebAug 1, 2024 · What is synaptic transmission? Generally speaking, it’s just another way to say neurotransmission. But it specifies that the communication occurring between brain cells is happening at the synapse as opposed to some other communication point.

Graphical Abstract Introduction Glutamate is the principal excitatory neurotransmitter in the central nervous system. Neurons release glutamate through Ca2+-dependent exocytosis which underlies fast synaptic transmission. Astrocytes may also release glutamate and WebApr 11, 2024 · Connexin 43, an astroglial gap junction protein, is enriched in perisynaptic astroglial processes and plays major roles in synaptic transmission. We have previously found that astroglial Cx43 controls synaptic glutamate levels and allows for activity-dependent glutamine release to sustain physiological synaptic transmissions and …
