The Brain & States of Consciousness- AP Psych
What is most likely to occur when the brain is repeatedly flooded with artificial opiates?
The brain stops producing endorphins.
Your conscious awareness of your own name and self-identity depends primarily on the normal functioning of your
cerebral cortex
According to Freud, the latent content of a dream refers to
its underlying but censored meaning
Direct stimulation of the motor cortex would be most likely to result in
movement of the mouth and lips
Sleep deprivation has been shown to
diminish immunity to disease
Which cognitive neuroscience term reflects the idea that "much of our everyday thinking, feeling, and acting operates outside our conscious awareness"?
dual processing
The cortical regions that are not directly involved in sensory or motor functions are known as
association areas
Psychologist Michael Gazzaniga asked split-brain patients to stare at a dot as he flashed HE·ART on a screen. HE appeared in the left visual field, ART in the right. When asked, patients said they saw
ART
Why is it dangerous to combine alcohol with a sleeping pill?
Alcohol and sleeping pills are depressants; their combined action reduces nervous system activity and can lead to death.
Which brain area is primarily involved with controlling speech?
Broca's area
Sleep researchers who are interested in brain wave activity are likely to use which kind of brain scan?
EEG
In 1847, phineas gage, a railroad construction foreman, survived when an explosion drove an iron rod through his head. The once friendly, soft-spoken Gage became irritable and dishonest. Gage's case provided evidence that which region of the brain plays a role in personality and behavior ?
Frontal lobes
How is the hypothalamus involved in sleep?
In response to decreasing light the hypothalamus' suprachiastmatic nucleus causes the pineal gland to increase production of melatonin, leading you to sleep.
In 1861, Paul Broca studied a stroke patient he called "Tan." He was called this because as a result of brain damage it was the only word he could pronounce. Based on Broca's early work, which of the following brain regions is involved in speech production?
Left frontal lobe
The surgical removal of a large tumor from Dane's occipital lobe resulted in extensive loss of brain tissue. Dane is most likely to suffer some loss of
Visual perception
When asked to describe a picture that showed two boys stealing cookies behind a woman's back, a patient replied, "Mother is away her working her work to get her better, but when she's looking the two boys looking the other part." Which brain region has most likely been damaged?
Wernicke's area
Which brain area is primarily involved with understanding and producing meaningful speech?
Wernicke's area
To demonstrate that brain stimulation can make a rat violently aggressive, a neuroscientist should electrically stimulate the rat's
amygdala
Which brain area is primarily involved with reading aloud?
angular gyrus
If a blind person uses one finger to read Braille, the brain area dedicated to that finger expands as the sense of touch invades the visual cortex. This is an example of
brain plasticity
Ellen volunteers during her AP psychology class to try to balance a yardstick on her two fingers. While her eyes are open, she finds the task quite easy. However, when she closes her eyes, she finds the same task almost impossible. Which brain region relies on visual information in coordinating our voluntary movements?
cerebellum
Cindi prefers to take exams in the late afternoon rather than during the morning, because her energy level and ability to concentrate are better at that time. Her experience most likely reflects the influence of the
circadian rhythm
Like his father, Martin has been abusing alcohol for many years. Using the biopsychosocial approach in helping him understand his behavior, psychologists would
examine additional psychological and social-cultural influences on his alcohol use.
To identify which specific brain areas are most active during a particular mental task, researchers would be most likely to make use of a
fMRI
Which of the following is the component of the limbic system that plays an essential role in the processing of new memories
hippocampus
The occurrence of REM rebound supports the notion that
humans, like most other mammals, need REM sleep
The brain structure that provides a major link between the nervous system and the endocrine system is the
hypothalamus
The secretions of the pituitary gland are most directly regulated by the
hypothalamus
Severing a cat's reticular formation from higher brain regions causes the cat to
lapse into a coma
Addictive drug cravings are likely to be associated with reward centers in the
limbic system
Shane, a straight-A student, remembers dreaming that he failed an important chemistry test. According to Freud, Shane's account represents the ________ content of his dream.
manifest
Your life would be most immediately threatened if you suffered destruction of the
medulla
Recent brain research contradicts previously held beliefs, indicating that new neurons are actually formed in the brain. What is this process called?
neurogenesis
REM sleep is called paradoxical sleep because
our nervous system is highly active, while our voluntary muscles hardly move.
The activation-synthesis theory best helps to explain why
people often experience sudden visual images during REM sleep
Some researchers suggest that the brain activity associated with REM sleep provides the sleeping brain with periodic stimulation. This finding supports which of the following dream theories?
physiological
Damage to the left cerebral hemisphere is most likely to reduce people's ability to
speak fluently
When the cat's amygdala is electrically stimulated the cat prepares to attack by hissing and arching its back. Which division of the autonomic nervous system is activated by such stimulation?
sympathetic
Your ability to experience the physical pleasure of a hot shower is most likely to be disrupted by damage to your
thalamus
The discomfort and distress that follow the discontinued use of certain drugs is called
withdrawal
