EXPLAINING OCD 2
neural explanations
basal ganglia
-
eg. washing, cleaning, checking
This area of the brain is involved in multiple processes including the co-ordination of psychomotor (motion) functions
Patients who suffer head injuries in this brain region often develop OCD-like symptoms, following their recovery.
worry circuit
-
The caudate nucleus (found in the basal ganglia) is responsible for intercepting and suppressing some of these minor worry signals, reducing their strength and then sending reduced strength messages back to the OFC
OFC is responsible for detecting potential hazards or dangers in the environment and then sending worry signals about these dangers to the thalamus
-
-
if the caudate nucleus is therefore not working properly, minor worry signals would not be suppressed
-
particular brain regions, in particular the basal ganglia and the ‘worry circuit’, are implicated in OCD.
strength
-
-
advances in neuroimaging (brain scanning) technology have enabled researchers to study specific brain areas in detail and to compare normal brain patterns with abnormal brain patterns
weakness
argue that a faulty learnt association can account for OCD as behavioural psychologists suggest that OCD may be learnt through classical conditioning and maintained through operant conditioning
