Questions and Answers
- 1.
Suppose your friend got hit in the head with a bowling ball (it was a very intense game!), and you asked if he was okay, but claims that he has no idea what you are saying, you are likely able to conclude that he has sustained damage to his ___________________.
- A.
Thalumus
- B.
Brocca's Area
- C.
Corpus Collosum
- D.
Hypothalumus
- E.
Wernicke's Area
Correct Answer
E. Wernicke's AreaExplanation
If your friend got hit in the head with a bowling ball and is unable to understand what you are saying, it suggests that he has sustained damage to his Wernicke's Area. The Wernicke's Area is responsible for language comprehension and understanding spoken words. Damage to this area can result in receptive aphasia, where the person is unable to understand or comprehend language.Rate this question:

The __________________ is the part of the brain responsible for taking sensory inputs and sending them to the appropriate area of the brain.
- A.
Hypothalamus
- B.
Hippocampus
- C.
Hypothalamus
- D.
Pons
- E.
Thalumus
Correct Answer
E. ThalumusExplanation
The thalamus is the part of the brain responsible for taking sensory inputs and sending them to the appropriate area of the brain. It acts as a relay station, receiving information from various sensory systems and then directing it to the appropriate regions for further processing. This allows for efficient and organized transmission of sensory information throughout the brain. The hypothalamus, hippocampus, and pons have different functions and are not specifically responsible for sensory input processing.Rate this question:

The _____________________ is the part that is most responsible for risk taking, emotion, and agression.
- A.
Amygdale
- B.
Frontal lobe
- C.
Reticular formation
- D.
Hypothalumus
- E.
Pons
Correct Answer
A. AmygdaleExplanation
The amygdala is responsible for risk taking, emotion, and aggression. It is a small almond-shaped structure located deep within the brain. It plays a crucial role in processing emotions, particularly fear and aggression. The amygdala is involved in the formation and storage of emotional memories and can trigger a fight-or-flight response when faced with a threat. Dysfunction or abnormalities in the amygdala can lead to various psychiatric disorders such as anxiety, depression, and aggression.Rate this question:

If it weren't for the _____________________, the two halves of our brains could never communicate with each other.
- A.
Hypothalumus
- B.
Amygdale
- C.
Corpus collosum
- D.
Hippocampus
- E.
Pons
Correct Answer
C. Corpus collosumExplanation
The corpus collosum is a bundle of nerve fibers that connects the two hemispheres of the brain. Without this structure, the two halves of our brains would not be able to communicate with each other effectively. The corpus collosum allows for the transfer of information and coordination between the left and right hemispheres, enabling various cognitive functions such as language processing, perception, and motor coordination. Its absence or damage can lead to conditions such as split-brain syndrome, where the hemispheres operate independently from each other.Rate this question:

The EEG is used to
- A.
Stimulate parts of the brain in order to see what function it serves.
- B.
Produce leisons to see what memory/bodily functions become inoperative.
- C.
Temporarily deactivate a part of the brain so that leisoning is unnecessary.
- D.
Uses electrical currents to measure brain activity.
- E.
Observe blood flow to see what part of the brain is working during a particular mental or physical task.
Correct Answer
D. Uses electrical currents to measure brain activity.Explanation
The correct answer is "uses electrical currents to measure brain activity." EEG stands for electroencephalogram, which is a test that measures electrical activity in the brain. It involves placing electrodes on the scalp to detect and record the electrical impulses produced by the brain cells. By analyzing these electrical currents, doctors and researchers can gain insights into brain function, identify abnormalities, and diagnose conditions such as epilepsy, sleep disorders, and brain injuries.Rate this question:

If one wanted to observe abstract thinking in the brain, the most likely place to look is in the
- A.
Hypothalumus
- B.
Hippocampus
- C.
Cerebrum
- D.
Pons
- E.
Thalumus
Correct Answer
C. CerebrumExplanation
The cerebrum is the most likely place to observe abstract thinking in the brain. It is the largest part of the brain and is responsible for higher cognitive functions such as thinking, reasoning, problem-solving, and abstract thought. The cerebrum is divided into two hemispheres and contains the cerebral cortex, which is highly developed in humans and plays a crucial role in abstract thinking and complex mental processes. The other options, such as the hypothalamus, hippocampus, pons, and thalamus, are involved in different functions such as regulating basic bodily functions, memory formation, and relaying sensory information, but they are not primarily associated with abstract thinking.Rate this question:

The cerebellum is mostly related to
- A.
Memory
- B.
Critical thinking
- C.
Balance
- D.
Sleep
- E.
Dopaminergic projections
Correct Answer
C. BalanceExplanation
The cerebellum is mostly related to balance because it plays a crucial role in coordinating and controlling movement. It receives information from the sensory systems and integrates it with motor signals to ensure smooth and coordinated movements. Damage to the cerebellum often results in balance problems, difficulty with coordination, and unsteady gait. While the cerebellum is also involved in other functions such as motor learning and some aspects of cognition, its primary function is maintaining balance and coordinating movements.Rate this question:

Which of the following brain structures would likely result in death if it is badly damaged?
- A.
Pons
- B.
Medulla
- C.
Corpus collosum
- D.
Cerebellum
- E.
Cerebrum
Correct Answer
B. MedullaExplanation
The medulla is responsible for regulating vital functions such as breathing, heart rate, and blood pressure. If the medulla is badly damaged, it can lead to a loss of control over these essential functions, potentially resulting in death.Rate this question:

What was the name of this person?
- A.
Phineas Gage
- B.
Hans Burger
- C.
Clark Hull
- D.
Ernest Hilgard
- E.
Inez Prosser
Correct Answer
A. Phineas GageExplanation
Phineas Gage is the correct answer because the question asks for the name of a person, and out of the given options, only Phineas Gage is a person's name. The other options are not relevant to the question.Rate this question:

Whch of the following would mpst likely result if the hypothalumus was in some way damaged?
- A.
Feeling unnecessarily hot
- B.
Decreased thirst
- C.
Increased hunger
- D.
Decreased sex drive
- E.
All of the above
Correct Answer
E. All of the aboveExplanation
The hypothalumus is the regulator of basic biological needs such as hunger, thirst, sex drive, and temperature.Rate this question:
