Exploring Brain Function and Change

What is neuroplasticity?

• The ability of the brain to generate new neurons throughout life.

• The brain's ability to reorganise itself by forming new neural connections.

• The process of neurotransmitter release in the synaptic cleft.

• The study of the brain's structure using imaging techniques.

Which neurotransmitter is primarily associated with mood regulation?

• Dopamine

• Serotonin

• Acetylcholine

• GABA

What does evolutionary psychology primarily focus on?

• The development of the human brain over an individual's lifetime.

• The influence of culture on human behaviour.

• The role of natural selection in shaping human behaviour and mental processes.

• The impact of neurotransmitters on human emotions.

Which part of the brain is primarily associated with memory formation?

• Amygdala

• Hippocampus

• Cerebellum

• Thalamus

What does the term "localisation of function" refer to in neuroscience?

• The idea that specific parts of the brain are responsible for specific functions.

• The distribution of neurotransmitters across different brain regions.

• The ability of the brain to adapt to new learning experiences.

• The process of brain development during childhood.

What is the primary difference between MRI and fMRI scans?

• MRI measures brain activity, while fMRI measures brain structure.

• MRI uses X-rays, while fMRI uses radio waves.

• MRI provides static images, while fMRI measures brain activity by detecting changes in blood flow.

• MRI is used for diagnosing brain injuries, while fMRI is used for diagnosing mental disorders.

What is the role of neurotransmitters in the brain?

• They provide energy to neurons.

• They transmit signals across synapses between neurons.

• They protect neurons from damage.

• They form the structural components of neurons.

Which brain imaging technique is most suitable for studying brain activity during a cognitive task?

• CT scan

• MRI

• fMRI

• PET scan

What does an fMRI scan measure to assess brain activity?

• Electrical impulses in neurons

• Blood oxygen levels

• Neurotransmitter concentrations

• Brain temperature

How does cortisol affect human behaviour during stress?

• It decreases heart rate and promotes relaxation.

• It increases alertness and prepares the body for a fight-or-flight response.

• It enhances memory recall and concentration.

• It reduces appetite and energy levels.
