use of brain imaging technologies in investigating the relationships between biological factors + behaviour (8/22)
INTRODUCTION
the BLA states that all cognitions, emotions and behaviours have a physiological basis
-
-
-
-
-
-
CONCLUSION
- primarily involving invasiveness + levels of radioactivity
-
however, they all contribute to our understanding of the relationship between biological factors + behaviour
brain imaging technologies = very useful in determining the relationship between biological factors + behaviour
Raine et al. (1997)
-
-
as the brain absorbs glucose, the glucose tracer is able to track brain activity
-
-
-
-
-
aim: investigate whether murders who plead not-guilty by reason of insanity (NGRI) show evidence of brain abnormalities
-
-
-
causes; fearlessness, unable to control violent behaviour + unable to learn from it
-
Raine utilised PET scan technology to investigate relationship between biological factors in criminals + their behaviour
-
-
-
Maguire et al. (2000)
compared them to already existing MRI scans of normal, healthy individuals
this mean there was a redistribution of grey matter in their brains, making other areas smaller in size
regular use of of spatial memory skills made neurons in certain areas of taxi drivers brain much stronger
-
-
-
Aim: investigate whether taxi drivers have differently structured hippocampi in their brains compared to normal people
-
-
-
MRI was able to observe + determine relationship between environmental enrichment on neuroplasticity, which effects behaviour in terms of memory
