Unit 2 Topic 2.6

An individual was admitted to the hospital after experiencing a mild tingling on the right side ofthe face and a sudden inability to speak. Using magnetic resonance imaging (MRI), a doctor would likely find

an abnormality in the brain tissue of the left hemisphere

People who have experienced severe damage to the frontal lobe of the brain seldom regain their ability to

make and carry out plans

The occipital lobe of the human brain contains the centers for

vision

Damage to a small part of the occipital lobe would most likely result in a

visual deficit

Where's the pons located?

Brainstem

Which of the following would most likely result from an injury to the medulla?

A life-threatening disruption of heartbeat and breathing

Damage to the cerebellum would most likely result in what?

A loss of motor coordination

Electrically stimulating a rat's amygdala would most likely produce which of the following?

Aggression

Damage to which of the brain structures may cause the inability to detect the emotional significance of facial expressions, especially those demonstrating fear?

Amygdala

Brain damage that leaves a person capable of understanding speech but with an impaired ability to produce speech most likely indicates injury to which of the following?

Broca's area

Which of the following parts of the brain is most active in decision-making?

Cerebral cortex

Whats Pons associated with?

Correct. The pons is associated with sleep and arousal, and acts as a bridge between other areas of the brain.

A person with damage to Broca's area would most likely demonstrate which of the following symptoms?

Difficulty with speech production

Which of the following is true about the pons?

It is the region of the brain that is most closely associated with sleep and arousal.

Which of the following is true of the reticular activating system?

It regulates levels of arousal.

Damage to the occipital lobe would most likely affect a person's

Language processing

Which of the following areas of the body has the largest number of sensory neurons?

Lips

The area of the brain stem that is important in controlling breathing is the

Medulla

The person most strongly associated with identifying deficits in the motor speech area and in the ability to produce speech is

Paul Broca

Significant damage to which of the parts of the brain will most likely cause a person to fall into a deep coma from which the person will be unable to awaken?

Reticular formation

If an individual has lost the ability to feel pain in the left arm, there is most likely damage to what area of the brain?

Right parietal lobe

For most people, which is an activity based in the right hemisphere of the brain?

Simple spatial reasoning

Function of Pons

Sleeping, waking, and dreaming

Hunger and eating are primarily regulated by which of the following?

The hypothalamus

Which of the following assertions is best supported by empirical evidence?

The two cerebral hemispheres are specialized to process different types of cognitive tasks.

A person will most likely develop aphasia as a result of damage to which of the following parts of the brain?

Wernicke's area

What's empirical evidence?

based on, concerned with, or verifiable by observation or experience rather than theory or pure logic.

Difficulty in typing smoothly on a keyboard would most likely result from damage to the

cerebellum

During a psychology experiment, a researcher uses a probe to lesion the ventromedial nucleus of a rat's hypothalamus. After the procedure the rat most likely will

eat more and gain weight

Stimulation of portions of the left temporal lobe of the brain during surgery will cause the patient to

hear sounds

The brain scans of people with amnesia are most likely to show damage to the

hippocampus

Brain lateralization refers to the

inclination for certain cognitive processes to be specialized to one hemisphere of the brain or the other (def of brain lateralization)

The right occipital lobe receives visual information from the

right half of both retinas

The occipital lobes contain

sensory and motor connections to other brain regions
