Forebrain Applied Questions Flashcards
What lobe is the location of the brain�s visual system?
Occipital Lobe
Helen has advanced Huntington’s disease, causing her to have trouble initiating and controlling movement. The damage of what forebrain structure is most likely responsible for these symptoms?
Basal Ganglia
When someone faces a situation that makes him feel both terrified and helpless, he may develop Post Traumatic Stress Disorder (PTSD). Later, things in the environment that are reminiscent of the trauma may trigger the same fear he experienced during the trauma. What part of the brain is responsible for organizing and remembering emotional events?
Amygdala
Research on the brains of people with schizophrenia suggests problems with the structure that organizes sensory information and routes it to appropriate parts of the brain; that is, the ________________. This malfunctioning structure may therefore be responsible for schizophrenic hallucinations and other disturbing sensory experiences.
Thalamus
What structure is located in the same position in the forebrain as a peel is on an orange?
Cerebral Cortex
What system of forebrain structures is involved in the storage and retrieval of memories, and coordinating behaviors needed to satisfy emotional and motivational urges?
Limbic System
What lobe receives input that gives rise to sensations of heat, touch, cold, balance, and body movement?
Parietal Lobe
Princess Aurora suffers from Sleeping Beauty syndrome, which causes her to sleep for sometimes 20 hours a day, to have unusual cravings for apples, and feel strong sexual desires towards whichever man kisses her lips. Which of her forebrain structures is most likely malfunctioning?
Hypothalamus
Scientists have suggested that the entire period of human evolution could be labeled the age of the ___________ lobe.
frontal lobe
Which lobe is found in the most posterior region of the forebrain?
Occipital Lobe
Which cortical region is most like the CEO of a company who doesn’t actually do anything herself but instead is responsible for managing the work of other employees in the company and for providing the company with strategy and vision?
prefrontal cortex
Lenny was in an accident that damaged the part of his brain responsible for creating memories. Though Lenny can remember things from before the accident, he can�t make new memories. If he meets someone, he won�t remember her the next time he sees her, even if he has met her several times. What part of Lenny�s limbic system was most likely damaged?
hippocampus
What type of cortex would be the first to process whether your back is being poked?
primary sensory cortex
Which part of the cerebral cortex controls 600 or more muscles involved in voluntary movements?
primary motor cortex
Damage to what lobe would leave an individual unable to comprehend written or spoken speech?
temporal lobe
When Keith drinks too many beers, he becomes a mean drunk and is more likely to physically assault others. What area of his forebrain has likely been impaired by the alcohol?
cerebral cortex
Lesions to what area of the forebrain will cause an animal not to become addicted to cocaine, amphetamines, and heroin?
mesolimbic pathway
The areas that comprise the ____________ cortex are sometimes referred to as the silent areas because when they are stimulated electrically, they do not trigger sensory experiences or motor responses.
association cortex
What type of cortex is thought to be involved in mental processes such as thought, memory, and perception?
association cortex
What forebrain structure is analogous to a radio broadcast transmitter which transponds or repeats the signal of another radio station to an area not covered by the signal of the originating station?
thalamus
What system of forebrain structures is involved in the storage and retrieval of memories, and coordinating behaviors needed to satisfy emotional and motivational urges?
limbic system
In the 1930s, Antonio Egas Moniz developed a surgical treatment called a lobotomy to reduce the symptoms of mental illness in disturbed patients. A lobotomy involved damaging or destroying the parts of the brain that are responsible for self-awareness, planning, initiative, and responsibility. Based on this information, what lobe was Moniz destroying?
frontal lobe
