Final answer:
The E) amygdala is the brain area that is extremely stimulated when an individual is feeling sad, as it processes emotional responses and influences the body's fight-or-flight reaction.
Step-by-step explanation:
The question asks which area of the brain is extremely stimulated when an individual is feeling sad. The correct answer to this question is (E) Amygdala.
The amygdala is part of the limbic system and is known for its role in processing emotions.
Research shows that the amygdala is involved in emotional responses and has strong connections with the hypothalamus, which in turn can influence the body’s response based on emotional state, such as the fight-or-flight response.
Specifically, when an individual feels sad, it can lead to increased activity in the amygdala, which is associated with mood and anxiety disorders.
Moreover, the amygdala's basolateral complex is critical for classical conditioning and assigning emotional values to learning and memory processes.
