Ryan's missed neuro Flashcards
The statement “I am sad because I cry” is most consistent with the
Select one:
A. James-Lange theory of emotion
B. Cannon-Bard theory of emotion
C. two-factor theory of emotion
D. Lazarus cognitive appraisal theory of emotion
Correct Answer is: A
The James-Lange theory states that emotions are the perceptions of bodily changes, either physiological changes such as increases in heart rate and muscle tension, or actual behavioral changes. In other words, the bodily/behavioral changes precede the emotion, rather than the other way around. The Cannon-Bard theory states that physiological changes are caused by emotions, the opposite of the James-Lange theory. Two-factor theory states that emotions are caused by interpretation of physical arousal; interpretation does not play the same role in the James-Lange theory. And Lazarus’ cognitive appraisal theory focuses on the role of cognitive appraisal in emotion; it divides the appraisal process into three stages: primary appraisal, secondary appraisal, and re-appraisal.
A patient with Parkinson's Disease is experiencing tremors. What transmitter is probably involved? Select one: A. Acetylcholine B. Glutamate C. Zyprexa D. Dopamine
Correct Answer is: D
A lack of norepinephrine at brain synapses is associated with depression, while excessive dopamine and norepinephrine are both associated with schizophrenia. Dopamine also plays a role in movement, and degeneration of neurons that secrete dopamine causes the muscular rigidity found in Parkinson’s disease.
Which of the following statements best reflects the cross-cultural findings on emotions?
Select one:
A. Most researchers have only found fear, anger, and sadness to be universal emotions.
B. Most researchers agree on the existence of 12 basic emotions. Incorrect
C. Most researchers have disputed the existence of universal basic emotions.
D. Most researchers have agreed on the existence of at least 6 basic emotions, but have disagreed on the inclusion of several other emotions as basic.
Correct Answer is: D
Interest in the existence of innate universal (cross-cultural) emotions began with Darwin in 1872 who found that the facial expressions of certain emotions were the same across different cultures. Many researchers since Darwin have tried to identify which emotions are universal. Most have agreed on the existence of at least six basic emotions (happiness, surprise, fear, sadness, anger, and disgust). However, there has been much disagreement on whether other emotions such as interest, guilt, and shame are also universal and innate emotions
Naltrexone (ReVia, Depade), an opiate antagonist, has been approved to treat alcohol abuse disorders by reducing the desire for alcohol after drinking has stopped and blocking the reinforcing effects or parts of the brain that “feel” pleasure when using alcohol. The most commonly experienced sides effects associated with naltrexone are:
Select one:
A. nausea, headache, insomnia, and anxiety.
B. abdominal cramping, night sweats, blurred vision, shortness of breath.
C. blurred vision, dizziness, excessive perspiration and gastrointestinal pain.
D. shortness of breath, increased dreaming, nausea, diarrhea.
Correct Answer is: A
Naltrexone, when used as an adjunct to psychosocial treatments for alcoholism, can provide an important period of sobriety, during which an individual learns to stay sober without it. Naltrexone therapy has been shown to improve treatment outcomes, reducing the percentage of days spent drinking (after stopping), the amount of alcohol consumed on a drinking occasion and relapse to excessive and destructive drinking. In other words, naltrexone is likely to reduce the urge or craving to drink and the risk of returning to heavy drinking. While individuals on naltrexone are less likely to relapse to heavy drinking following a lapse in abstinence, naltrexone does not make people “sober up”, does not alter alcohol’s acute effects on cognitive functioning and is approved as an adjunct to psychosocial treatment not a replacement. Unlike disulfiram (antabuse), naltrexone does not appear to alter the absorption or metabolism of alcohol and does not have major adverse effects when combined with alcohol although some have increased nausea caused by drinking alcohol while taking naltrexone. Common side effects noted at the initiation of treatment in approximately 10 percent of individuals include nausea, headache, dizziness, fatigue, nervousness, insomnia, vomiting, constipation and anxiety.
A whisper being audible in a library reading room, but not in a busy cafeteria is explained by: Select one: A. the all-or-nothing principle B. the "law of effect" C. Weber's law D. the "law of proximity"
Correct Answer is: C
Weber’s law is one of the psychophysical laws that explains the relationship between physical stimuli and their psychological effects. According to Weber’s, the “just noticeable difference” in the stimulus is proportional to the magnitude of the original stimulus, explaining why a whisper can be heard in a quiet room but not in a noisy one.
Fetal alcohol spectrum disorders (FASDs) is a term used:
Select one:
A. for clinical diagnosis of prenatal alcohol exposure
B. to describe the differentiation of effects between fetal alcohol syndrome and fetal alcohol effects
C. to describe the range of effects from prenatal alcohol exposure for conditions that have some but not all of the clinical signs of fetal alcohol syndrome (FAS)
D. to describe the range of effects from prenatal alcohol exposure
Correct Answer is: D
Fetal alcohol spectrum disorders (FASDs) is an umbrella term describing the range of effects that can occur in an individual exposed to alcohol during pregnancy including physical, mental, behavioral effects, and/or learning disabilities.
FASDs include FAS as well as other conditions in which individuals have some, but not all, of the clinical signs of FAS. The term FAE has been used to describe behavioral and cognitive problems in children who were exposed to alcohol prenatally, but who do not have all of the diagnostic features of FAS. In 1996, the Institute of Medicine (IOM) replaced FAE with the terms alcohol-related neurodevelopmental disorder (ARND) and alcohol-related birth defects (ARBD). ARND describes the mental and behavioral impairments such as learning disabilities, poor school performance, poor impulse control, and problems with memory, attention and/or judgment. ARBD describes the malformations of the skeletal system and major organ systems such as defects of the heart, kidneys, bones, and/or auditory system.
The term FASDs is not intended for use as a clinical diagnosis.
Anosognosia is most often due to damage to the: Select one: A. corpus callosum B. left temporal lobe C. right parietal lobe D. occipital lobe
Correct Answer is: C
Anosognosia is an inability, or unwillingness, to recognize one’s own functional impairment. It most often occurs in people who have left-sided hemiplegia due to damage to the right parietal lobe. Many of these patients maintain normal intellectual functioning, despite the serious lack of self-awareness of their physical disability. The parietal lobe contains the somatosensory cortex which is normally responsible for integrating somatosensory information with visual and other sensory information.
Clomipramine and fluoxetine alleviate the symptoms of Obsessive-Compulsive Disorder by affecting levels of Select one: A. epinephrine. B. norepinephrine. C. dopamine. D. serotonin.
Correct Answer is: D
If you’re unsure about the correct answer to a question about neurotransmitters, serotonin is usually a good guess since it’s involved in so many functions and activities. And, in fact, in OCD, the usefulness of the antidepressant drugs is believed to be due to their ability to increase serotonin activity.
Peripheral vision is processed in the: Select one: A. frontal lobe B. temporal lobe C. anterior occipital lobe D. posterior occipital lobe
Correct Answer is: C
anterior occipital lobe
posterior occipital lobe
You probably were able to narrow the choices down to these two options, knowing that vision is processed in the occipital lobe. However, you should also know that peripheral vision is processed in the anterior occipital lobe. Central vision is processed in the posterior occipital lobe.
An advantage of clozapine (Clozaril) over conventional antipsychotic drugs is that it is
Select one:
A. significantly more effective for the negative symptoms of Schizophrenia.
B. less likely to produce anticholinergic effects.
C. less likely to cause agranulocytosis.
D. often effective for those who don’t respond to conventional drugs.
Feedback
Correct Answer is: D
The atypical antipsychotic clozapine affects different neurotransmitters than conventional antipsychotics and, to some degree, has different side effects. For example, although it doesn’t produce tardive dyskinesia, it does cause agranulocytosis, a potentially fatal blood disease. An important advantage of clozapine is that it’s often effective when conventional antipsychotic drugs aren’t.
Your friend Bill has been involved in a motorcycle accident that resulted in a head injury. His neurologist has indicated that Bill is experiencing aphasia. As a knowledgeable psychologist, you would give Bill all the following news about his injury except:
Select one:
A. because his language loss is not severe, he has a better chance of recovery.
B. the greatest amount of recovery will occur in the next 3 months.
C. since he is right-handed he will probably exhibit milder aphasia.
D. he is lucky to be sixteen instead of sixty-six.
Correct Answer is: C
This is an extremely difficult question. That’s why you will review these tests several times.
since he is right-handed he will probably exhibit milder aphasia.
In regard to this answer, the opposite is true; Subirana (1969) found that left-handers generally exhibit milder aphasia, and recover more thoroughly and more quickly than right-handers. The course of recovery from aphasia due to head injury is related to several factors including age at time of injury-especially during the first three months (Kertesz, 1979).
Starvation in Anorexia is believed to be precipitated by:
Select one:
A. high levels of serotonin
B. low levels of serotonin
C. low levels of tryptophan
D. low levels of serotonin and tryptophan
A
High levels of serotonin have been linked to both appetite suppression and anxiety while low levels have been linked to depression and appear to contribute to binge eating. Research by Kaye et al (1997) proposes that anxiety is caused by high levels of serotonin and individuals with Anorexia temporarily relieve anxiety through starvation which reduces tryptophan, which then reduces the level of serotonin. The lowered serotonin fosters a sense of calm and personal control. Inversely, low levels of serotonin are believed to precipitate binge eating in Bulimia as sweets and carbohydrates increase serotonin and elevate mood.
The brain system that mediates the general adaptation syndrome identified by Selye is the
Select one:
A. hypothalamic-hippocampal-prefrontal axis.
B. hypothalamic-pituitary-adrenal axis.
C. thalamic-hippocampal-limbic axis.
D. thalamic-limbic-prefrontal axis.
Correct Answer is: B
General adaptation syndrome is a model of stress put forth by Hans Selye in the 1930s. According to this model, exposure to stressful stimuli causes a predictable series of reactions, even if the stressor is positive. He divided these reactions into three phases: alarm, resistance, and exhaustion. In the alarm phase, the stress is identified and adrenaline is produced in order to trigger the fight-or-flight response. The resistance phase involves utilizing the body’s resources in an attempt to cope with the stress. And in the exhaustion phase, the body’s resources are depleted and the body cannot maintain its normal function. Autonomic nervous symptoms such as sweating and increased heart rate may reappear, and, if this phase is extended, long-term problems such as ulcers or depression could result. The hypothalamic-pituitary-adrenal axis (HPA axis) refers to physiological interactions and feedback among the hypothalamus, pituitary gland, and the adrenal gland. This axis regulates reactions to stress, including the general adaptation system. It is also involved in regulating other processes, including digestion, the immune system, emotions, and sexuality.

The primary symptoms of normal pressure hydrocephalus are:
Select one:
A. headache followed by vomiting, downward deviation of the eyes and urinary incontinence
B. a rapid increase in the size of the head, headache followed by vomiting, gait disturbance
C. a rapid increase in the size of the head, downward deviation of the eyes, dementia
D. gait disturbance, urinary incontinence, dementia/mental disturbance
Correct Answer is: D
Hydrocephalus is a condition primarily characterized by excessive accumulation of cerebrospinal fluid (CSF) within the ventricles inside the brain. As the CSF builds up, it causes the ventricles to enlarge or dilate causing the pressure inside the head to increase and potentially harmful pressure on the tissues of the brain. Hydrocephalus may be congenital or acquired. The specific causes of hydrocephalus are unknown. Congenital hydrocephalus is thought to be caused by a complex interaction of environmental factors and a possible genetic disposition or developmental problem. The most common developmental problems that may lead to hydrocephalus include: spina bifida, failure of the tissue surrounding the spinal cord to close properly; aqueductal stenosis, a narrowing of a channel in the brain that connects two ventricles; and encephalocele, herniation of the brain. Acquired hydrocephalus can affect individuals of all ages and may result from a disease or condition such as encephalitis, intraventricular hemorrhage, meningitis, head trauma, stroke, infection, complications of surgery, tumors and cysts.
Age, disease progression and how well a person can tolerate increased cerebrospinal fluid pressure all affect the symptoms of hydrocephalus. Common symptoms in infancy include an unusually large head, a rapid increase in the size of the head and a bulging “soft spot” on the top of the head. In older children and adults, symptoms may include headache followed by vomiting, nausea, papilledema or swelling of the optic disk, downward deviation of the eyes, problems with balance, poor coordination, gait disturbance, urinary incontinence, slowing or loss of development (in children), lethargy, drowsiness, irritability, or other changes in personality or cognition, including memory loss. A condition that mainly affects people over 60 years of age is normal pressure hydrocephalus. It is caused by defective absorption of CSF, in which the excess CSF enlarges the ventricles but does not increase pressure on the brain. It may result from injury, illness or infection although many people develop normal pressure hydrocephalus without an obvious cause. It typically starts with difficulty walking. Urinary incontinence often develops, along with a type of dementia marked by slowness of thinking and information processing.
Hydrocephalus is diagnosed through clinical neurological evaluation and by using cranial imaging techniques such as ultrasonography, computer tomography (CT), magnetic resonance imaging (MRI), or pressure-monitoring techniques. The most effective treatment is surgical insertion of a shunt although endoscopic third ventriculostomy (ETV) is growing in popularity as an alternative treatment method for hydrocephalus.
