The phenomenon of declining physiological effects of taking a drug after sustained use is referred to as

tolerance

The psychodynamic theory of dreaming would postulate that

dreams fulfill unconscious wishes

the hormone associated with fight of flight

a person who's people is not producing enough testosterone will most likely exhibit

fatigue

The idea that there is a part of the mind that is not directly accessible to awareness but still drives a person's thinking and behavior is most directly attributable to

If a body does not have enough potassium, how might that affect neuronal firing?

The neurons will struggle to fire because there will not be enough positively charged ions to trigger the firing of the neuron.

They increase the likelihood that a postsynaptic neuron will fire.

A drug that is used to treat seizures functions by preventing inhibitory neurotransmitters from returning to the presynaptic neuron. This slows the rate of neurons firing by increasing the amount of the inhibitory neurotransmitter in the synapse. The drug is most likely to be classified as a

GABA
