Cerebellum

Question 10

What role does 'synaptic pruning' play in the healthy brain?

Answer

It eliminates weak or redundant synaptic connections

Answer

It improves the efficiency of neural communication

Answer

It leads to permanent cognitive decline

Answer

Diffusion Tensor Imaging (DTI)

Answer

Transcranial Magnetic Stimulation (TMS)

Answer

Standard Blood Pressure Monitoring

Question 13

What does 'critical period' mean in the context of plasticity?

Answer

A timeframe where the brain is exceptionally sensitive to environmental input

Answer

A period during which specific neural circuits must be shaped by experience

Answer

A phase of static neural connectivity

Answer

The period following total brain death

Question 14

Which neurotransmitters are commonly linked to the modulation of plastic changes?

Answer

Answer

Glutamate

Answer

Melatonin

Answer

Histamine
