Module 6

Question 1

What is the cerebral cortex

Answer 1

The surface interconnected neural cells covering the cerebral hemispheres, the bodies ultimate control and information processing center

Question 2

Where is each of the 4 main lobes

Answer 2

Frontal; behind forehead. parietal; at the top and to rear. occipital; back of head. temporal; just above the ears

Question 3

How was the motor cortex mapped

Answer 3

Due to the lack of receptors, electrical shocks to different areas revealed answers

Question 4

If the motor cortex is for sending messages out, what receives messages from the senses

Answer 4

The somatosensory cortex

Question 5

What do hallucinogenic drugs like LSD provide hallucinations?

Answer 5

The drug intercepts, and increases the communication between the visual cortex and other brain regions, causing high stimulation

Question 6

Where is the visual cortex?

Answer 6

occipital lobe (back of the brain)

Question 7

Where is the auditory cortex?

Answer 7

temporal lobe (just above the ears)

Question 8

How does frontal lobe damage impact personality

Answer 8

It can make someone more agitable, dishonest, profane, and overall less moral

Question 9

What part of the brain performs mathematical and spatial reasoning?

Answer 9

the parietal lobes

Question 10

What lobe helps with face recognition

Answer 10

Underside of right temporal lobe

Question 11

Why are “brain hot spots” and phrenology not great ways to understand the brain?

Answer 11

The brain works in unison in a lot of cases, brain scans show activity of it working together, while some things run automatically in the background. This is known as functional connectivity

Question 12

What is functional connectivity?

Answer 12

Communication among distinct areas of the brain responsible for memory, language, attention, social skills, etc.

Question 13

What is neuroplasticity?

Answer 13

The ability of the brain to change in response to experience

Question 14

Where does the left visual field transmit to?

Answer 14

The right hemisphere

Question 15

Where does the right visual field transmit to?

Answer 15

The left hemisphere

Question 16

How did split-brain-surgery patients differ from regular people

Answer 16

Surprisingly little, because the communication lines between the hemispheres were cut, they cannot communicate. For example, if one is told to walk, the right hemisphere begins walking, but the left hemisphere doesn’t know, it improvised in an experiment saying “I’m going to get a coke”

Question 17

Where do brain scans reveal activity for brain waves, blood flow, and glucose consumption when a PERCEPTUAL task is asked to be performed

Answer 17

The right hemisphere

Question 18

Where may math and speaking actions usually happen

Answer 18

the left hemisphere

Question 19

The left hemisphere is quick, but the right hemisphere is essential for:

Answer 19

Making inferences, helping modulate speech, helping orchestrate self awareness

Question 20

What is the frontal lobe responsible for

Answer 20

Personality, emotions, motor, problem solving, reasoning

Question 21

What is the temporal lobe responsible for

Answer 21

Language, hearing, speech,

Question 22

What is the parietal lobe responsible for?

Answer 22

Sensory

Question 23

What is the Occipital lobe responsible for

Answer 23

Vision

Question 24

What is neurogenesis

Answer 24

The formation of new neurons, also known as baby neurons from deep in the brain migrating and connecting elsewhere
