AP PSYCHOLOGY

Detailed explanation-1: -Overall, these results suggest that paranoia is related to higher resting neuronal activity in the amygdala, as well as in broader sensory and frontal regions.

Detailed explanation-2: -Our work has demonstrated that over activation of a brain region called the amygdala seems to be critically important for paranoia. The amygdala is responsible for detecting threats in the environment, and for most people, threat signals from the amygdala are evaluated and regulated by the frontal cortex.

Detailed explanation-3: -In MRI studies of schizophrenia, the most consistent findings include reduced gray matter volumes of the medial temporal, superior temporal, and prefrontal areas.

Detailed explanation-4: -Amygdala lesions result in emotional deficits, such as facial affect recognition, that occurs also in schizophrenic patients, especially paranoid, compared to non-paranoid.

Detailed explanation-5: -The hippocampus and amygdala are believed to be involved in the pathology of schizophrenia.
