(Enlarged ventricles) what are ventricles?
Fluid filled cavities
(Enlarged ventricles) in some individuals with schizophrenia what is found?
Lateral ventricles appear to be larger
(Enlarged ventricles) where are the lateral ventricles found?
The cerebral hemispheres
(Cortical atrophy) cortical atrophy means loss of what?
Neurons in the cerebral cortex
(Cortical atrophy) where can cortical atrophy occur?
All over the brain or in a specific area
(Cortical atrophy) if it occurs all over the brain the brain looks like it has what?
Shrunk
(Cortical atrophy) cortical atrophy leads to loss to what associated with these areas?
Cognitive functions
(Cortical atrophy) atrophy results in widening of what?

Left
(Reversed cerebral asymmetry) in some individuals with schizophrenia which hemisphere is larger?
Right (Reversed cerebral asymmetry)
(Reversed cerebral asymmetry) people with schizophrenia having smaller left ventricle could explain what symptom?
