Tetanus-Induced Long-Term Potentiation Long-term potentiationis initiated when postsynaptic neurons become depolarized,NMDAreceptor channels are activated, and Ca2+flows into the postsynaptic neuron(10, 11). One way to induce LTP is to use high-frequency stimulation to release large amounts ofneurotran...
Long-term potentiation (LTP) is a cellular model of the memory processes that occurs in many nerve cells, usually at glutamatergic synapses. For this reason, glutamatergic synapses being the most abundant in the brain, LTP has been widely proposed as a mechanism of memory. Recent findings suppor...

(i) When the contributions to LTP by p, n, and q are maximized, and p alone is decreased, another high-frequency stimulation elicits additional LTP. The additional potentiation is only associated with decreases in paired-pulse facilitation (PPF) suggesting an increase in p. (ii) There is ...
Is the statement true or false? Long-term potentiation refers to: a. the increased ability to retain long-term memories b. the increased efficiency of synaptic transmission between neurons when learning takes place c. the increased ability to learn d. the potential to...

The concept Hebb described is now referenced as long-term potentiation (LTP) at the synaptic level, through which the relative efficacy of the connection between two neurons, typically treated as a weighting value of the connecting synapse, increases due to the effects of a pre-synaptic action ...
Induction of long-term potentiation (LTP) of the synaptic connection between two hippocampal glutamatergic neurons in a neural network formed in cell culture resulted in a specific pattern of potentiation at other connections within the network. We found that potentiation propagated from the site of ...
