Abnormalities in the limbic system, which includes the hippocampus and amygdala, have been consistently linked to schizophrenia. The limbic system is involved in regulating emotions, motivation, and memory, and dysfunction in this system may contribute to the positive and negative symptoms of schizophrenia. Reduced activity in dopamine pathways and inactive brain receptors related to hearing and color are also associated with schizophrenia, but these are not brain abnormalities. Increased activity in the frontal lobe is associated with some symptoms of schizophrenia, but it is not a consistent finding across all individuals with the disorder.
