Answer keys **Multiple-Choice Questions (MCQs)** 1. **b) Amygdala** ✅ - The **amygdala** is primarily responsible for **emotion processing**, particularly fear and threat detection. 2. **b) Limbic system** ✅ - The **limbic system** is a group of structures in the brain involved in emotion, memory, and motivation. 3. **c) Processing emotions** ✅ - The **amygdala** is critical in processing emotions and linking them to sensory stimuli. 4. **c) Most sensory modalities** ✅ - The **amygdala receives input from multiple sensory systems** (e.g., visual, auditory, olfactory). 5. **c) Fear** ✅ - The amygdala is **most strongly associated with fear processing**, though it also processes other emotions. 6. **b) Heightened emotional responses and anxiety disorders** ✅ - **Overactivation** of the amygdala has been linked to **PTSD, anxiety, and excessive fear responses**. 7. **c) Orbitofrontal cortex** ✅ - The **orbitofrontal cortex (OFC) and amygdala** work together in **decision-making and emotional regulation**. 8. **b) Fear conditioning** ✅ - **Fear conditioning** is a form of learning where the amygdala helps associate stimuli with fear responses. 9. **b) Glutamate** ✅ - **Glutamate** is the primary **excitatory neurotransmitter** in the amygdala, influencing fear and emotion. 10. **d) All of the above** ✅ - **Schizophrenia, autism, PTSD, and anxiety disorders** all show **amygdala dysfunction**. 11. **b) Fear** ✅ - **Amygdala damage impairs fear recognition**, making it hard to recognize fearful expressions in others. 12. **c) Temporal lobe** ✅ - The **amygdala is located in the anterior temporal lobe**, deep within the brain. 13. **b) Emotional responses** ✅ - The amygdala **links sensory perception to emotional experiences**. 14. **a) Hippocampus and orbitofrontal cortex** ✅ - The **hippocampus (memory) and OFC (decision-making)** work with the amygdala in emotion regulation. 15. **b) Increased fear response and hypervigilance** ✅ - **PTSD patients often have an overactive amygdala**, leading to heightened fear responses and anxiety. **True/False Questions** 16. **False** ❌ - The amygdala processes **many emotions**, not just fear (e.g., anger, sadness, pleasure). 17. **True** ✅ - The **amygdala is involved in both emotions and decision-making**, particularly through its OFC connections. 18. **False** ❌ - The **amygdala is in the temporal lobe, not the occipital lobe** (which is for vision). 19. **True** ✅ - The **hippocampus and amygdala interact**, linking **memory with emotions**. 20. **True** ✅ - The **orbitofrontal cortex and amygdala** communicate to help regulate emotions and decision-making. 21. **False** ❌ - The amygdala **processes unconscious emotional stimuli**, meaning it can react without conscious awareness. 22. **True** ✅ - Damage to the **amygdala impairs fear recognition** in facial expressions. 23. **True** ✅ - **PTSD is linked to amygdala hyperactivity**, making fear and anxiety responses stronger. 24. **True** ✅ - The **amygdala receives sensory input from multiple sources** (e.g., vision, hearing, touch). 25. **True** ✅ - The amygdala is involved in **fight-or-flight responses**, preparing the body to respond to danger. 26. **True** ✅ - **Autism research shows abnormal amygdala activation** during emotional processing tasks. 27. **False** ❌ - The **amygdala is a bilateral structure**, meaning it exists on **both sides of the brain**. 28. **True** ✅ - **Fear conditioning** is a key function of the amygdala, helping us learn to avoid danger. 29. **True** ✅ - The **amygdala links emotions with autonomic and endocrine responses**, like heart rate changes. 30. **True** ✅ - **The amygdala plays a key role in social behavior**, making it relevant in **autism and emotional disorders**.
