long time ago, there once was an anti-drug public service announcement campaign that showed fried eggs in a pan with the voiceover, "This is your brain on drugs." Let's find out why that ad campaign is true. 1) Pick a non-legal drug. 2) Research what it does to the brain in detail. 3) Are addicts of this drug's brains different from brains of non-addicts? 4) Why or why not? 5) What treatments are used for addicts of this drug? 6) What helps people recover from this drug's addiction besides medicines?

- In PET scans, red areas are brain regions that are most active, while blue, yellow, and green areas are least active. Figure 13.24 shows PET scans of normal brain activity (left) and (right) of the brain of a person while using cocaine. The frontal lobes of the brain hemispheres are toward the top of the scans. Their neurons play major roles in reasoning and other intellectual functions. Looking at these scan images, how do you suppose cocaine may affect mental functioning?While visiting the Center for Addiction and Mental Health (CAMH) in Toronto, you have the rare opportunity to observe a client with schizophrenia during a PET scan. The client is a chronic user of cannabis and was asked to use cannabis 15 minutes before the scan took place. What is likely to be observed from the PET scan? Question 59 options: a) Reduced activity in the globus pallidus b) Increased activity in the limbic system c) Increased glucose metabolism in frontal lobe d) Increased size of hippocampus1) Describe what happens in your nervous system when you touch a hot frying pan. 2) Contrast the functions of the autonomic and somatosensory nervous systems. 3) Contrast schizophrenia with major depression in two (2) ways. 4) Contrast Alzheimer's Disease with Parkinson's Disease in two (2) ways. 5) Someone has a missing or broken corpus callosum. What behaviors would you expect from that person? Why? 6) Why do we need electrical synapses? 7) Can the central nervous system make new cells? Where and why?

John had been taking haloperidol (Haldol) but stopped taking it weeks ago, telling his case manager it was “the poison that is making me sick.” Yesterday, John was brought to the hospital after neighbors called the police because he had been up all night yelling loudly in his apartment. Neighbors reported him saying, “I can’t do it! They don’t deserve to die!” and similar statements. John appears guarded and suspicious and has little to say to anyone. His hair is matted, he has a strong body odor, and he is dressed in several layers of heavy clothing even though the weather is warm. So far, John has been refusing any offers of food or fluids. When the nurse approached John with a dose of haloperidol, he said, “Do you want me to die?” What additional assessment data does the nurse need to plan care for John? Identify the three priorities, nursing diagnoses, and expected…John Jones, age 33, has been admitted to the hospital for the third time with a diagnosis of paranoid schizophrenia.

- It is possible to treat addiction by prescribing drugs that block the effects of the psychoactive substance. For example, naloxone blocks opiate receptors, reducing the pleasurable effects of opioids and alcohol. These types of treatments are called: A) agonist treatments. B) aversive treatments. C) antidrug vaccines. D) antagonist treatments.16) Nancy was three when a car accident damaged a crucial portion of her brain that controlled language functioning. Following the accident, Nancy was unable to speak, although she could understand the meaning of the words being spoken to her. From the information provided in this scenario, we can infer that the brain damage Nancy suffered affected her A) Wernicke's area. B) limbic system. C) Broca's area. D) amygdalaEach of these brightly colored sticky notes represents a piece of information that someone doesn’t want to forget. Although we are all forgetful sometimes, most people do not have trouble remembering things that are important or routine to us, such as our friend’s name or how to get to class. Our brain, the control center of the nervous system and the rest of the body, normally allows us to retain and recall information. But if the brain becomes damaged, a person may need to rely excessively on external reminders — like this wall of sticky notes — rather than being able to trust their own memory. That is if they are able to remember to write things down in the first place. One person having trouble with their memory is Rosa, who is 68 years old. Rosa has been having difficulty remembering where she has set down objects in her house and forgot about a few doctor’s appointments and lunches she planned with friends. Her family began to notice that she would sometimes not recall recent…
- The following is an example of how a patient with schizophrenia responds to a question from the healthcare worker: Healthcare worker: “Why do you think some people believe in God?” Patient: “People believe in God because of toys. Embryology creates flowers behind the garages. There are no bread in the house.” What term best describes the pattern of disorganized speech exhibited by the patient? Question 54 options: a) Clang association b) Word salad c) Neologisms d) VerbigerationResearchers have discovered several neurological issues in the brains of patients with affective (mood) disorders. Which of the following neurological anomalies is found in bipolar patients during a manic episode, but NOT in patients experiencing depression? A) Reduced brain tissue in prefrontal areas and hippocampus. B) Increased metabolic activity in part of the prefrontal cortex. C) Enlargement of the amygdala and hypothalamus, leading to greater stress responses and higher cortisol levels. D) Reductions in overall brain activity, and especially in prefrontal regions and other circuits that regulate emotions.It is possible to treat addiction by prescribing drugs that block the effects of the psychoactive substance. These types of treatments are called: A) agonist treatments. B) aversive treatments. C) antidrug vaccines. D) antagonist treatments.
