⩥ An example of volume neurotransmission is:
Answer: Dopamine in the prefrontal cortex
⩥ The direct role of transcription factors is to:
Answer: Influence gene expression
⩥ The term epigenetics refers to:
Answer: A process determining whether a given gene is expressed or
silenced
⩥ Presynaptic reuptake transporters are a major method of inactivation
for which of the following?
Answer: Serotonin and GABA
⩥ What is constitutive activity?
Answer: Signal transduction when no agonist or inverse agonist is bound
to the receptor.
,⩥ A partial agonist has what effect on neurotransmission?
Answer: Net agonism when neurotransmission is deficient.
Net antagonism when neurotransmission is excessive.
Both of the above answers are correct
⩥ Agonists cause ligand-gated ion channels to:
Answer: Open more frequently
⩥ Which of the following is true?
Answer: Both positive and negative allosteric modulations are possible
only in the presence of a neurotransmitter
⩥ When voltage-sensitive sodium channels are open and activated, the
flow of sodium is:
Answer: Into the neuron
⩥ Which of the following are involved in regulating neurotransmission
via excitation-secretion coupling?
Answer: Both of these which are voltage-sensitive sodium channels and

⩥ A 21-year-old man who has just been diagnosed with schizophrenia
presents with his parents. He speaks with a reserved and simple
language processing style; he is able to understand and relate to simple
, questions but seems to get lost when the pace of the conversation
between the clinician and parents accelerates. when reviewing the
patient's history, what pattern of cognitive functioning prior to psychosis
onset would you be most likely to find?
Answer: Impaired cognitive functioning premorbidly with further
decline during the prodromal phase.
⩥ Dopamine (DA) receptors can be categorized as D1 like (D1 and D5
receptors) and D2 like (D2, D3, and D4 receptors). What differentiates
the two groups of receptors?
Answer: D1-like receptors are excitatory and D2-like receptors are
inhibitory.
⩥ Symptoms of schizophrenia are hypothetically attributable to
malfucntioning in the:
Answer: Mesocortical and mesolimbic pathways
⩥ For which set of disorders is psychosis considered an associated
feature rather than a defining feature for diagnosis?
Answer: Bipolar mania, Parkinson's disease.
⩥ The activation of N-methyl-d-aspartate (NMDA) receptors requires
the presence of:
Answer: Glutamate and glycine.
