Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What is the biological change that occurs during rehearsal which also increases the neuron’s firing potential?
A
LONG-TERM POTENTIATION
B
FLASHBULB MEMORY
C
ENCODING
D
CHUNKING
Explanation: 

Detailed explanation-1: -Long term potentiation is usually an autocrine effect, where the neurotransmitter diffuses back to the presynaptic cell and activates metabotropic receptors that cause long duration depolarization, increasing the odds of firing action potentials.

Detailed explanation-2: -Long-term potentiation (LTP) is a process involving persistent strengthening of synapses that leads to a long-lasting increase in signal transmission between neurons. It is an important process in the context of synaptic plasticity. LTP recording is widely recognized as a cellular model for the study of memory.

Detailed explanation-3: -Synaptic plasticity (see below) is the ability of neurons to bring about changes in the connections between neuronal networks in response to use or disuse.

Detailed explanation-4: -There are multiple types of glutamate receptors, and glutamate plays a particularly important role in learning and memory. NMDA glutamate receptors, in particular, are a necessary component in memory formation, as modeled by long term potentiation.

Detailed explanation-5: -Long-term potentiation (LTP) in the hippocampus enhances the ability of a stimulus to produce cell firing, not only by increasing the strength of the EPSPs, but also by increasing the efficiency of the input/output (I/O) function of pyramidal neurons.
