LTP mean long term Potentiation. It is the persistent strengthening of a synaptic connection. It may work for a minute or hours .It induce may due to strong tetanic stimulation to synapse. LTP is the primary mechanism of learning and memory.
Some Presynaptic change
Some postsynaptic change
AMPA and NMDA are the two receptor that is important in point of view of LTP. The AMPA receptor is paired with an ion channel so that when glutamate binds to this receptor , this channel allow sodium ions to enter the post synaptic neuron.
Hope I fully explain your doubt. Thank You
