Norepinephrine

Submit

14. Which of the following accurately describes the all-or-none principle in neural transmission?

A neuron fires only if stimulation exceeds threshold

Neurons fire at varying intensities depending on stimulus strength

Weak stimuli produce partial action potentials

The strength of the action potential varies with stimulus intensity

15. Which neurotransmitter system is most directly involved in reward and motivation?
