Localization Of Function 1 Flashcards
Definition of Localization of Function
Localization of function is a theory which claims that different areas of the brain are responsible for specific behaviour’s cognitions and emotions

If you are in an argument an you feel mad/angry at someone your amygdala is firing.
First assumption of Biology
Behaviour is the product of physiology
Second assumption of Biology
Behaviour can be genetically inherited
Third assumption of Biology
Animal research is valuable
Who was behind the Maguire study
University of London scientists
Explain the test cab drivers have to pass in lodon
They have to pass a test which usually takes the avg person at least two years to master. It’s a knowledge test of all the streets and navigation things.
What was the conclusion of the study
The posterior hippocampus in taxi drivers was larger than nontaxi drivers. The largest hippocampus prosteriors were of drivers with the most experience.
What does the study suggest?
that the brain can change itself according to the requirements of the owner and its environment.
What was the aim of the study?
To see whether different environments or experiences can cause changes in the
hippocampus of humans.
What was the hypothesis
To find out if human beings with more navigation experience would show an increase in
hippocampul volume.
What was the procedure like
they chose a sample of self-selected taxi drivers who have all had to learn and take an exam of thousands of streets landmarks, places, etc which normally takes 3-4 years and relies heavily on navigation. Hence ideal for the test. They compared their brain structures, sizes, and volume with nontaxi drivers using an MRI.
What conclusion did they make about lof
The more people use their spatial memory, the larger the hippocampus appears to become in the
posterior region.
What conclusion can you make about lof
shows that the posterior hippocampus is specifically involved in spatial memory and navigation. London taxi drivers, who rely heavily on these skills, had a larger posterior hippocampus compared to non-taxi drivers, suggesting that this brain region is specific to the function of spatial navigation.
