| # | Front | Back | Hint |
|---|---|---|---|
| 1 | A person reports feeling intensely euphoric and motivated after receiving a reward. Which neurochemical system is most likely involved? | Dopamine system, as it is associated with reward, motivation, and pleasure responses. | Think of the 'dopamine rush' when rewarded. |
| 2 | In a stressful situation, an individual shows increased heart rate and agitation. Which hormone is primarily responsible for these responses? | Adrenaline (epinephrine), which prepares the body for 'fight or flight' responses. | Remember 'adrenaline' as the hormone of immediate stress response. |
| 3 | A person with depression is treated with SSRIs. Which neurotransmitter's activity are these medications targeting? | Serotonin, as SSRIs increase serotonin levels in the synaptic cleft to improve mood. | SSRIs 'boost' the mood-related neurotransmitter. |
| 4 | During a failure or setback, an individual feels a lack of motivation and pleasure. Which neurochemical imbalance might be involved? | Reduced dopamine activity, which affects reward and motivation pathways. | Think of 'dopamine deficiency' as a lack of reward signals. |
| 5 | A person frequently experiences anxiety and panic attacks. Which neurochemical imbalance could contribute to these symptoms? | Imbalance in serotonin and/or gamma-aminobutyric acid (GABA), which help regulate anxiety and reduce neural excitability. | Serotonin and GABA are calming agents in the brain. |
| 6 | In addiction, which neurochemical pathway is primarily involved in reinforcing drug-seeking behavior? | The mesolimbic dopamine pathway, which reinforces the rewarding effects of addictive substances. | Think of the 'reward circuit' as the dopamine highway. |
| 7 | A person under chronic stress has elevated cortisol levels. How might this affect their neurochemical balance related to mood? | Chronic cortisol can disrupt serotonin and dopamine systems, potentially leading to depression or anxiety. | Cortisol is the stress hormone that can interfere with mood-regulating neurotransmitters. |
| 8 | Which neurochemical is most directly implicated in the regulation of sleep and wakefulness, and what might its imbalance cause? | Serotonin and norepinephrine, with imbalances potentially causing sleep disorders or depression. | Serotonin plays a role in mood and sleep regulation. |
| 9 | How does increased activity of GABA influence behavior in stressful or anxious situations? | Increased GABA activity produces calming effects, reducing anxiety and neural excitability. | GABA is the brain's primary inhibitory neurotransmitter. |
| 10 | A person with obsessive-compulsive disorder (OCD) is often treated with medications targeting which neurochemical system? | Serotonin system, as serotonergic dysregulation is linked to OCD symptoms. | SSRIs are commonly used for OCD treatment. |
| 11 | What role does norepinephrine play during a 'fight or flight' response? | It increases alertness, arousal, and prepares the body for action by increasing heart rate and blood flow. | Norepinephrine is key for arousal during stress. |
| 12 | In cases of ADHD, which neurochemical system is often targeted by medication to improve attention and impulse control? | Dopamine and norepinephrine systems, as stimulants enhance their activity. | Think of stimulants as boosting 'attention chemicals.' |
| 13 | If an individual experiences anhedonia (loss of pleasure), which neurochemical system might be underactive? | Dopamine system, which is involved in reward and pleasure sensations. | Anhedonia suggests a lack of reward signals. |
| 14 | How does chronic stress affect serotonin levels, and what behavioral effects might this produce? | Chronic stress can decrease serotonin levels, increasing vulnerability to depression and anxiety. | Stress can 'deplete' mood-stabilizing chemicals. |
| 15 | A patient is experiencing severe mood swings and impulsivity. Which neurochemical imbalance might be involved? | Dysregulation of serotonin and dopamine pathways, affecting mood and impulse control. | Mood swings often involve multiple neurotransmitter systems. |
| 16 | Which neurochemical is most associated with the 'pleasure' and 'reward' aspects of addictive behaviors? | Dopamine, especially within the mesolimbic pathway. | The 'pleasure chemical' linked to addiction. |
| 17 | In what way does serotonin influence aggression and impulsivity? | Lower serotonin activity is linked to increased aggression and impulsivity. | Serotonin acts as a 'brake' on impulsive behavior. |
| 18 | What neurochemical changes are often observed in individuals experiencing post-traumatic stress disorder (PTSD)? | Altered levels of norepinephrine and serotonin, often with heightened norepinephrine activity and disrupted serotonin signaling. | PTSD involves hyperarousal and mood disturbances. |
| 19 | A person with social anxiety shows heightened amygdala activity. Which neurochemical system might be overactive? | The serotonin and GABA systems, with possible overactivity of stress-related pathways like norepinephrine. | Amygdala hyperactivity relates to fear and anxiety. |
| 20 | How does the neurochemical theory explain the calming effect of alcohol? | Alcohol enhances GABA activity, increasing inhibitory effects and producing sedation and relaxation. | GABA = brain's 'brake' system. |
