Question 1

If a neurosurgeon directly stimulated parts of your somatosensory cortex,which of the following would you most likely experience?

Accepted Answer

The somatosensory cortex is responsible for processing tactile sensations, such as touch. Therefore, direct stimulation of this area would most likely result in experiences of touches on the body.

Question 2

The somatosensory cortex is located in the ________ lobes.

Accepted Answer

The somatosensory cortex is responsible for processing sensory information related to touch, temperature, and pain. It is located in the parietal lobes, specifically in the postcentral gyrus.

Question 3

Which regions of the cerebral cortex lie at the back of the head and receive visual information?

Accepted Answer

The occipital lobes are located at the back of the head and are responsible for processing visual information. Choices B, C, and D are not located in the visual processing regions of the cerebral cortex.

Question 4

To trigger a person's hand to make a fist,José Delgado stimulated the individual's

Accepted Answer

José Delgado's stimulation of the individual's hand to make a fist would require activating the motor cortex, which is responsible for voluntary muscle movements. The hippocampus is involved in memory consolidation and spatial navigation, while the somatosensory cortex processes touch and sensory information from different parts of the body. The corpus callosum is a band of fibers that connects the two hemispheres of the brain and does not play a direct role in voluntary muscle movements.

Question 5

Which of the following is located in the occipital lobes?

Accepted Answer

The visual cortex is located in the occipital lobes and is responsible for processing visual information from the eyes.

Question 6

Which regions of the cerebral cortex are positioned closest to our eyes?

Accepted Answer

The frontal lobes are positioned closest to our eyes, located right behind the forehead, and are involved in complex cognitive functions, motor skills, and expression of emotions.

Question 7

Which region of the human brain best distinguishes us from other animals?

Accepted Answer

The cerebral cortex, particularly the prefrontal cortex, is responsible for complex human behaviors such as decision-making, reasoning, social interaction, and language. The size and complexity of the human cerebral cortex are much greater than in any other animal, which is why it is considered the most distinguishing feature of the human brain.

Question 8

Regions of the cerebral cortex involved primarily in higher mental functions such as learning are called

Accepted Answer

Association areas are regions of the cerebral cortex involved primarily in higher mental functions such as learning, memory, language, and decision-making. The motor cortex is responsible for controlling voluntary movement, the corpus callosum is a bundle of nerve fibers connecting the two hemispheres of the brain, and the somatosensory cortex processes sensory information from the body.

Question 9

The brain devotes more tissue within the ________ for body areas that are highly sensitive to touch such as the lips.

Accepted Answer

The somatosensory cortex is responsible for processing sensory information from different parts of the body, including touch. The brain devotes more tissue to areas that are highly sensitive to touch, such as the lips, within the somatosensory cortex.

Question 10

The auditory cortex is responsible for hearing and is located right above the ear.The visual cortex is responsible for vision and is located

Accepted Answer

The visual cortex is responsible for processing visual information and is located at the back of the head, in the occipital lobe.

Question 11

The visual cortex is located

Accepted Answer

The visual cortex is located at the back of the head, specifically in the occipital lobe.

Question 12

The two cerebral hemispheres that make up 85 percent of the brain's weight are referred to as the

Accepted Answer

The cerebrum refers to the two cerebral hemispheres that make up 85 percent of the brain's weight.

Question 13

A monkey with electrodes implanted in its brain is able to move a computer cursor simply by thinking about the move.This brain-computer interface best illustrates the potential value of

Accepted Answer

Cognitive neural prosthetics, also known as brain-computer interfaces, involve using electrodes implanted in the brain to allow individuals to use their thoughts to control external devices or prosthetics. This technology has the potential to greatly improve the quality of life for individuals with disabilities or injuries that prevent them from using their limbs. The scenario described in the question is a clear illustration of how this technology works. Options A, B, and D do not directly apply to this scenario.

Question 14

Alana suffered a brain disease that destroyed major portions of her temporal lobes.Alana is most likely to suffer some loss of

Accepted Answer

The temporal lobes are responsible for processing auditory information, so damage to this area would most likely result in some loss of auditory perception.

Question 15

Which of the following is located in the temporal lobes?

Accepted Answer

The auditory cortex, responsible for processing auditory information, is located in the temporal lobes of the brain.

Question 16

The parietal lobes are to ________ as the occipital lobes are to ________.

Accepted Answer

The parietal lobes are primarily responsible for processing sensory information related to touch and spatial awareness, while the occipital lobes are primarily responsible for processing visual information. Therefore, the correct pairing is "sensing touch" for the parietal lobes and "seeing" for the occipital lobes. Choices A, C, and D are incorrect pairings.

Question 17

The thin surface layer of interconnected neural cells that covers the cerebrum is called the

Accepted Answer

The description best fits the definition of the cerebral cortex, which is the thin surface layer of interconnected neural cells that covers the cerebrum. The amygdala, corpus callosum, and hippocampus are all structures located within the brain, but they do not specifically refer to the surface layer of the cerebrum.

Question 18

An area at the rear of the frontal lobes that controls voluntary movements is called the

Accepted Answer

The motor cortex, located at the rear of the frontal lobes, is responsible for controlling voluntary movements. The somatosensory cortex is responsible for processing sensory information from the body, while the corpus callosum is a bundle of fibers connecting the two hemispheres of the brain. The frontal association area is responsible for higher cognitive functions such as decision making, planning, and problem solving.

Question 19

Suppose that a speech synthesizer could produce specific words when signaled by the brain activation patterns involved when a person merely thinks about these words.This would be an illustration of

Accepted Answer

The scenario described is an example of cognitive neural prosthetics, which involves using brain signals to control external devices or prosthetics. In this case, the speech synthesizer is being controlled by brain activation patterns associated with specific words, allowing the person to produce speech without physically speaking.

Question 20

Direct stimulation of areas within the motor cortex would most likely result in

Accepted Answer

The motor cortex is responsible for controlling voluntary movements. Stimulation of specific areas within it would most likely result in movement of the corresponding body part, such as the mouth and lips. Thus, choice D is the best answer. A, B, and C are incorrect because they are related to other brain regions and not directly related to the motor cortex.
