Draganski et al (2004)

Question 1

What biblical approach does Draganski et al (2004) fit into?

Answer 1

Neuroplasticity

Question 2

Aim

Answer 2

Find out whether the human brain can change in response to an external stimulus

Question 3

Method

Answer 3

• Random smaple of volunteers who cound not juggle
• One group was labelled as the jugglers while the other group was labelled the non-jugglers.
• The jugglers were instructed to practice juggling everyday for three months, while the non-jugglers were insturcted to libe their normal lives.
• At the end of the three months, both groups were instructed to live their normal lives and to not practice juggling for another three months.
• All the participants had their brains scanned before the experiment, after the first three month period and after the second three month period.

Question 4

Results

Answer 4

The first scan was identical for all of the participants, but the second scan was different in each group. The non-jugglers scans stayed the same, but the jugglers had a large grey mass in the mid-temporal area of the brain. After the second . three month trial the non-jugglers still had . the same brain scans, and the jugglers still had the grey mass, but the amount had decreased significantly.

Question 5

Findings

Answer 5

This shows the synaptic plasticity of neuroplasticity can be provoked by an external stimulus.

Question 6

Why neuroplasticity?

Answer 6

The brain changed in relation to the new external stimulus, which is in this case the practicing of juggling everyday.
