What is behavioral plasticity?
Morphological plasticity is the tendency of a species to physically change appearance due selective breeding. Some species, like dogs, have a high degree of morphological plasticity - a few generations can turn a wolf into a chihuahua - whereas others, such as humans, have such a low degree that thousands of years of separation yields only minor changes to facial structure and hair type. The mechanisms which govern this effect are complex and numerous, but there seems to be a correlation between high plasticity and the species' natural rate of environmental adaptability.
What is synaptic fatigue?
Synaptic fatigue, or short-term synaptic depression, is an activity-dependent form of short-term plasticity that affects neuronal efficacy and results in the temporary inability to fire and therefore transmit an input signal. It is thought to be a form of negative feedback in order to physiologically control particular forms of nervous system activity.[1] Synaptic fatigue involves the temporary inhibition of neurons due to constant and persistent stimulation, where the fatigue effects are generally dependent upon the type and frequency of stimuli present. The underlying cause of fatigue on the synapse is temporary depletion of synaptic vesicles that house neurotransmitters in the presynaptic cell. The neurotransmitters are released to propagate the signal to the postsynaptic cell. It has also been hypothesized that synaptic fatigue could be a result of postsynaptic receptor desensitization or changes in postsynaptic passive conductance, but recent evidence has suggested that it is primarily a presynaptic phenomenon.
Where does a synapse occur?
Synapses occur at synaptic cleft (or also called as "synaptic gap"). The location of "synaptic cleft" depends on the types of synapses:axo-dendritic synapse : between axons and dendritesaxo-somatic synapse : between axons and cell bodiesaxo-axonic synapse : between axons and axonsdendro-denritic syanpse : between dendrites and dendrites
How do axon terminals maintain their synaptic position at dendrites?
Synaptic adhesion molecules span the synaptic cleft, holding the axon terminal to the dendrite. There are a number of different kinds of synaptic adhesion molecules, which typically have a portion that starts slightly inside an axon terminal and protrudes outside more than halfway into the synaptic cleft, meeting and over-lapping and sticking against a companion sam protruding similarly from a dendrite, thus maintaining the relative position of the axon terminal and dendrite.
How is synaptic potential associated with pain?
What is the role of synaptic potentials in the perception of pain? What kind of reaction might you expect if synaptic potentials were removed?
What does the synaptic plasticity do in learning?
It allows neuronal development in response to novel experiences.

Is plasticity a physical property or a chemical property?
Plasticity is a physical property.
What is synaptic potential?
synaptic potential
The are sack-like structures found inside the synaptic knob containing chemicals?

The lifespan perspective maintains that plasticity is possible throughout the entire lifespan What is plasticity?
Plasticity (sociology), is the capacity for positive change in response to environmental demands.
