A polygraph machine is often called a "lie detector," although it does not detect lies. Instead, it responds to changes in

autonomic arousal

The part of the neuron that is responsible for receiving signals from other neurons is called

dendrite

The autonomic nervous system is most directly involved in

digesting food

Which of the following is reduced during a fight-or-flight reaction?

digestion

Which of the following neurotransmitters has been linked to Parkinson's disease and schizophrenia?
