Neurotransmission and Genetics Quiz

What is neurotransmission?

• The process of cell division

• Communication between neurons using neurotransmitters

• The transport of oxygen to the brain

• The release of hormones into the bloodstream

What does the “lock and key” analogy describe?

• DNA replication

• Hormone secretion

• How neurotransmitters bind to specific receptor sites

• How the brain stores memories

What are vesicles?

• Sacs that store and transport neurotransmitters

• Enzymes that break down neurotransmitters

• Brain receptors

• Electrical impulses between neurons

What is reuptake?

• When neurotransmitters are destroyed in the synapse

• When neurotransmitters are reabsorbed into the presynaptic neuron

• When neurotransmitters move to the receptor sites

• When neurotransmitters are created

Which neurotransmitter affects mood?

• Serotonin

• Dopamine

• Glutamate

• Adrenaline

Why does alcohol cause blackouts?

• It increases serotonin

• It blocks glutamate receptors, preventing memory formation

• It releases more dopamine

• It decreases PFC activity

What is the placebo effect?

• A change in behaviour due to belief in a treatment

• A drug’s direct chemical effect

• A type of neurotransmitter

• Brain imaging error

What does the serotonin deficit hypothesis propose?

• Low serotonin levels cause aggression

• High serotonin causes aggression

• Serotonin increases empathy

• Serotonin decreases inhibition

What is inhibitory response control?

• The ability to control impulsive reactions

• The brain’s fight-or-flight response

• The ability to produce serotonin

• The process of neurotransmission

Which brain regions are affected by low serotonin?

• Hippocampus and thalamus

• Amygdala and prefrontal cortex

• Cerebellum and corpus callosum

• Brainstem and occipital lobe
