Investigating the Brain Flashcards

1️⃣ Familiarise yourself with the flashcards:

  • Look through all the flashcards to see what’s on both sides.
  • Make sure you understand the information on each card. If something’s unclear, click the link to the revision notes at the bottom of the page for more details.

2️⃣ Test yourself:

  • Look at the question or prompt on each card and try to remember the answer before flipping it over.
  • Check the answer and make a note of any cards you find challenging and need to go over more.

3️⃣ Consistently Review and Practice:

  • Use spaced repetition: spend more time on the cards you struggle with and go over them more often.
  • Regularly review all the flashcards to help you better understand and retain the information over time.

Note: We may include questions that have multiple correct answers. It’s useful to remember specific examples to understand these concepts better.

How have scientists gained most of their knowledge about brain functions?

By studying patients with brain damage and using animal brains for research, although human brains are more complex and findings may not always be directly transferable.

What are two main methods used by neuroscientists to investigate brain functions?

Brain scans and electrical stimulation.

How do MRI scanners work and what are they used for?

MRI scanners use strong magnetic fields and radio waves to produce detailed images of the brain, showing which parts are active during tasks.

What is electrical stimulation of the brain and how is it used in research?

It involves using a weak electrical current to stimulate parts of the brain, and observing the patient’s experiences (e.g. involuntary movement and changes in perception).

What is an electroencephalogram (EEG) and what is it used for?

An EEG is a test that detects electrical activity in the brain using electrodes on the scalp, used to evaluate brain disorders by detecting changes in brain activity.

Why is treating brain damage and diseases challenging?

Because neurons take a long time to regenerate after damage, and untreated brain disorders can worsen, reducing quality of life. Brain surgery is often necessary but carries significant risks.
