Task: Answer Verification
Input (English): Question: Are cerebrospinal fluid corticotropin-releasing hormone levels elevated in monkeys with patterns of brain activity associated with fearful temperament?
Answer: These findings suggest that, in primates, the fearful endophenotype is characterized by increased fearful behavior, a specific pattern of frontal electrical activity, increased pituitary-adrenal activity, and increased activity of brain CRH systems. Data from other preclinical studies suggests that the increased brain CRH activity may underlie the behavioral and physiological characteristics of fearful endophenotype.
Output (English): yes
