Localization and Neuroplasticity Quiz

What does brain plasticity refer to?

• The brain's inability to alter its structure

• The brain's ability to stay static throughout life

• The brain's inability to change as a result of learning

• The brain's ability to grow connections between neurons

What was the aim of the study by Maguire et al (2000) on London taxi drivers?

• To investigate the effect of long-term stress on memory

• To study the impact of music training on brain plasticity

• To compare the hippocampal volume of taxi drivers and non-drivers

• To measure the effect of environmental stressors on the hippocampus

What is the process called when synapses become stronger through repeated use?

• Neural arborization

• Synaptic pruning

• Long-term potentiation

• Synaptic plasticity

What happens to synapses that are not used or under-stimulated?

• They lead to protein synthesis

• They undergo neural arborization

• They go through synaptic pruning

• They result in dendritic branching

How does synaptic plasticity work according to biologists?

• Use it or you lose it

• Synaptic pruning leads to protein synthesis

• Synapses become weaker through repeated use

• Synapses become stronger through under-stimulation

What was the key finding of the study by Maguire et al (2000) regarding the hippocampi of London taxi drivers?

• No difference in hippocampal size between taxi drivers and non-drivers

• Posterior hippocampi were larger in taxi drivers

• Posterior hippocampi were smaller in taxi drivers

• Anterior hippocampi were larger in taxi drivers

What is the process that removes synapses that are no longer needed in the brain?

• Synaptic plasticity

• Neural arborization

• Synaptic pruning

• Long-term potentiation

What were the findings of the Draganski study?

• No change in the hippocampus

• The jugglers showed a larger amount of grey matter in the mid-temporal area

• The participants who juggled had lost grey matter in the mid temporal area

• Non jugglers showed a larger amount of grey matter in the mid temporal area.

What does the term 'plasticity' mean in the context of the brain?

• The ability of the brain to resist any form of damage

• The ability of the brain to remain static and unchanging

• The ability of the brain to only change its structure but not its function

• The ability of the brain to change its function and structure in response to environmental changes

What happened to HM as a result of his surgery?

• He had no memory issues

• He developed anterograde amnesia

• He lost all memories

• He developed retrograde amnesia
