"biological explanations for SZ: Neural correlates and the dopamine hypothesis" Flashcards
The Neural correlates explanation states that what things may be linked with the development of SZ
Abnormalities in the Brain
brain scan techniques such as what are used to study the idea of Neural correlates
FMRI scans
when using FMRI scans to study brain activity, who’s brains are compared
Neuro-typical brains and SZ sufferers brains
when using FMRI scans, why do we compared the brains of a SZic with a Neurotypical
to identify regions linked to SZ
which part of the brain has been shown to be enlarged in sufferers of SZ
Ventricles
who conducted a meta-analysis that supported the idea that SZ sufferers had enlarged ventricles when compared to a control group
Raz and Raz
in Raz and Raz’s study, what % of the schizophrenics had increased ventricle size in comparison to the control group
over 50%
in SZ, enlarged ventricles are associated with damage to which area of the brain
Pre-Frontal Cortex
brain damage to the Pre-Frontal cortex has been associated with which types of symptoms in SZ
Negative Symptoms
what is a negative symptom of SZ that is associated with damage to the Pre-Frontal Cortex
Avolition (poor Motivation)
who conducted research to support the role of Neural correlates to explain SZ
Suddath Et Al
what technique did Suddath et al use to investigate brain structure
MRI scans
in Suddath et al’s research, who was the sample
A pair of Monozygotic twins
in Suddath et Al’s research,what did one of the twins suffer with
Schizophrenia
what was the finding of Suddath et Al’s research into neural correlates
the SZ twin had larger ventricles compared to the non-SZ twin
Suddath et Al’s research suggests that which brain abnormality DOES play a role in developing SZ
Enlarged Ventricles
Suddath et Al’s research also increases which aspect of the neural correlate argument
the Validity
the Dopamine Hypothesis states that WHAT in the brain appear to work differently in people with SZ
Neurotransmitters
which neurotransmitter in particular is said to be highly involved in SZ
Dopamine (DA)
Individuals with SZ may suffer from which 2 conditions in relation to DA?
Hyperdopaminergia and Hypodopaminergia
People suffering with SZ may also have too many WHAT
D2 Receptors
in SZ, where are D2 receptors located
Post-Synaptic Neuron
In which location of the brain is Hyperdopaminergia seen in SZ
the Sub Cortex
Hyperdopaminergia refers to when an individual has what level of dopamine activity
High Level of Dopamine activity
in which specific region of brain do sufferers of SZ have high dopamine activity
Broca’s area
what is Broca’s area said to be responsible for
Speech Production
High dopamine activity in Broca’s area has thus been associated with which specific positive symptom of SZ
Auditory Hallucinations
