Module 5

Question 1

Lesion means

Answer 1

To destroy

Question 2

Optogenics

Answer 2

A technique neuroscientists use to activity of individual neurons

Question 3

What does EEG stand for

Answer 3

Electroencephalogram

Question 4

What does an EEG do?

Answer 4

Amplifies the readout of brainwaves from the surface

Question 5

What does MEG stand for

Answer 5

magnetoencephalography

Question 6

What is done in a MEG

Answer 6

Isolate the brains magnetic fields through specialized rooms

Question 7

What does PET stand for

Answer 7

Positron emission tomography

Question 8

What happens in a PET scan

Answer 8

Shows brain activity through consumption of chemical fuel

Question 9

What does MRI stand for?

Answer 9

Magnetic resonance imaging

Question 10

What is done in an MRI?

Answer 10

The brain is scanned through a strong magnetic field, which aligns the spinning atoms of brain molecules. A radio wave pulse temporarily disorients the atoms, revealing the soft tissue of the brain

Question 11

What does fMRI stand for

Answer 11

Functional magnetic resonance imaging

Question 12

What is the purpose of an fMRI

Answer 12

Reveal the brains function as well as it’s structure

Question 13

How does an fMRI work

Answer 13

By detecting blood rushing to the head

Question 14

What does fNIRS stand for

Answer 14

functional near infrared spectroscopy

Question 15

What does an fNRIS do

Answer 15

Shines an infrared light on blood molecules to identify brain activity. Much more portable than other tools making it ideal for travel work

Question 16

Diffusion spectrum imaging attempts to:

Answer 16

Map the brains long-distance connections

Question 17

What does the brainstem do

Answer 17

Regulate heartbeat and breathing

Question 18

What do the pons do

Answer 18

Helps coordinate movement and control sleep. They are located just above the medulla

Question 19

What does the thalamus do

Answer 19

Receives information for all senses besides smell, routes the information to higher brain areas. It is located at the top of the brainstem

Question 20

What does the reticular formation do

Answer 20

Filters stimuli and relays important information to brain areas, it is a network of nerves that extends from the spinal cord right up through the thalamus

Question 21

What does the cerebellum do

Answer 21

“The little brain.” It enables nonverbal learning and skill memory. It plays a role in awareness, vocabulary, reading, and quick response time. The cerebellum is located at the rear of the brainstem, it is the size of a baseball.

Question 22

What is the amygdala

Answer 22

two lima-bean sized neural clusters, responsible for aggression and fear

Question 23

What is the hypothalamus

Answer 23

Responsible for command chain governing bodily maintenance, such as hunger, thirst, temperature, sexual behavior. This is the core of maintaining homeostasis in humans. It is located below the thalamus

Question 24

What is the hippocampus

Answer 24

The sea-horse shaped brain structure responsible for conscious and explicit memories.
