CH3

Question 1

Corpus Callosum

Answer 1

thick band of nerve fibres connecting the 2 hemispheres (supports communication b/w 2 hemispheres)

Question 2

Contralateral Control

Answer 2

each hemisphere controls opposite of body

Question 3

Frontal Lobe

Answer 3

movement, abstract thinking, planning, memory, and judgement

Question 4

Parietal Lobe

Answer 4

information about touch

Question 5

Occipital Lobe

Answer 5

visual information

Question 6

Temporal Lobe

Answer 6

hearing and language

Question 7

Somatotopic Map (sensory homunculus)

Answer 7

each point on skin is represented by corresponding area in the contralateral cortex, but the map is distorted

Question 8

Cortical Magnification

Answer 8

enlarged representation in cortical somatotopic map/sensory homunculus relative to skin area

Question 9

Brain Plasticity

Answer 9

the brain’s ability to be changed

Question 10

Phantom Limb Syndrome

Answer 10

Even after losing a part of their body, some patients continue to feel sensations where the missing part would be

Question 11

Mirror box procedure

Answer 11

put hand inside box and see reflection and seeing that phantom hand is moving allows brain to think that hand is moving even when not there

Question 12

Electroencephalography (EEG)

Answer 12

records electrical activity in the brain

Question 13

Magnetoencephalography (MEG)

Answer 13

records magnetic fields generated by the brains’ electrical activity

Question 14

Structural Brain Imaging

Answer 14

provides information about the basic structure of the brain

Question 15

Computerized Axial Tomography (CT)

Answer 15

takes a series of x-ray photographs from different angles and shows different densities of tissue in the brain

Question 16

Magnetic Resonance Imaging (MRI)

Answer 16

uses a strong magnetic field to line up the nuclei of specific molecules in the brain tissue

Question 17

Functional Brain Imaging

Answer 17

provides information about the activity of the brain while people perform various kinds of cognitive/motor tasks

Question 18

Functional Magnetic Resonance Imaging (fMRI)

Answer 18

detects the difference b/w oxygenated hemoglobin & deoxygenated hemoglobin when exposed to magnetic pulses

Question 19

Positron Emissions Tomography (PET)

Answer 19

a harmless radioactive substance is injected into a person’s bloodstream; measure the amount of radioactivity in each brain regions

Question 20

Diffusion Tenor Imaging (DTI)

Answer 20

: visualizes white matter pathways (fiber bundles that connect brain regions)

Question 21

Transcranial Magnetic Stimulation (TMS)

Answer 21

delivers a magnetic pulse and deactivates neurons in the cerebral cortex for a short period, temporarily mimicking brain damage

Question 22

split brains

Answer 22

no communication b/w the hemispheres

Question 23

global processing

Answer 23

seeing the big picture

Question 24

local processing

Answer 24

seeing it for what makes up the big picture

Question 25

central nervous system

Answer 25

composed of the brain and spinal cord, receives sensory information from the external world, processes & coordinates info and sends commands to skeletal and muscular systems for action

Question 26

peripheral nervous system

Answer 26

set of nerves that conveys information b/w skeletal muscles and central nervous system, humans have conscious control over this & use to perceive, think, and coordinate behaviours
