Class 4

Question 1

Electroncephalograph (EEG)

Answer 1

device used to record electrical activity in the brain

Question 2

Computerized axial tomography (CT) scan

Answer 2

locate lesions or tumors

Question 3

Magnetic Resonance Imaging (MRI)

Answer 3

structure of the brain and can help localize brain damage. Nothing about functions of the brain

Question 4

Diffusion tensor imaging (DTI)

Answer 4

rate and diffusion or movement of water molecules along white matter pathways. Maps the connectivity of the brain

Question 5

Positron emission tomography (PET)

Answer 5

Shows activity in the brain while someone performs a task

Question 6

functional magnetic resonance imaging (fMRI)

Answer 6

difference between oxygenated hemoglobin and deoxygenated hemoglobin when exposed to magnetic pulses.

Can localize changes in brain activity (over briefer periods than PET)

Question 7

Transcranial Magnetic Stimulation (TMS)

Answer 7

activates and deactivates regions of the brain with a magnetic pulse, temporarily mimicking brain damage

Question 8

Hindbrain

Answer 8

medulla, pons, cerebellum

controls info coming in and out of spinal cord

Question 9

Midbrain

Answer 9

substantia nigra, superior, and inferior colliculus

important for orientation and movement

Question 10

Forebrain

Answer 10

cortex (sulcus, gyrus), corpus callosum, basal ganglia, limbic system (amygdala, hippcampus), thalamus, hypothalamus

complex cognitive, emotional, sensory, and motor functions (2 parts, cerebral cortex and underlying subcortical structures)

Question 11

4 parts of cerebral cortex

Answer 11

frontal, parietal, temporal, occipital lobes

Question 12

Frontal lobe

Answer 12

areas for movement, abstract thinking, planning, memory, and judgment

motor control, emotional inhibition, language production (Broca’s aphasia), planning, judgment

Question 13

temporal lobe

Answer 13

responsible for hearing and language

auditory processing, language comprehension (wernicke’s aphasia), object/face recognition (prosopagnosia), memory

Question 14

parietal lobe

Answer 14

processing info about touch

spatial awareness (visual neglect), somatosensation (sensory humunculus)

Question 15

occipital lobe

Answer 15

processes visual info

visual processing (blindsight ex: can only see one thing like the word search guy bc hes completely unaware)

Question 16

nervous systems

Answer 16

central (CNS, brain and spinal cord)
Peripheral (PNS, CNS to organs and muscles)
Somatic (voluntary muscles and CNS)
Autonomic (ANS, made of sympathetic and parasympathic. involuntary and automatic commands that control blood vessels, body organs, and glands)
sympathetic (part of ANS, prepares body for action in challenging or threatening situations)
parasympathetic (part of ANS, helps body return to normal resting state)
