Visual pathway

Answer 3

Retina-optic nerve-optic chaism-optic tract- lateral geniculate nucleus-optics radiation-visual cortex

Question 6

Sulcus

Answer 6

small grooves dividing the gyri/gyrus

Question 7

Cortical Blindness

Answer 7

loss of vision without causes
= bilateral lesions inside Occipital lobe

Question 8

Primary Olfactory Cortex

Answer 8

interprets smell
-> only sensory info not routed

Question 9

Arcuate Fascicules

Answer 9

white matter pathway connecting wernicke’s + broca’s area
= coordinated speech

Question 10

Primary Gustatory Cortex

Answer 10

Main site involved w taste
-> specific neurons for sweetness, sourness, saltiness, bitterness

Question 11

Olfactation + Gustation

Answer 11

olfact.=sensation of smell
gust=sensation of taste

Question 12

Broca’s aphasia

Answer 12

can comprehend words can’t physically talk

Question 13

Cerebellum

Answer 13

Coordination persicion + motor movements
location=inferior to transverse fissure

Question 14

Limbic System

Answer 14

set of structures inside the brain
-> not separate system but collection of cerebrum

Question 15

Primary somatosensory Cortex

Answer 15

involved w processing temp. pressure + pain
bodily awareness-> space + time

Question 16

Broca’s area

Answer 16

speech production
-> posterior inferior frontal gyrus

Question 17

Fusiform gyrus

Answer 17

facial + bodily recognition
word / speech recognition
color info processing

Question 18

Primary auditory cortex

Answer 18

process auditory info
responsible for hearing+ understanding what’s heard

Question 19

orbitofrontal cortex

Answer 19

plays a role in emotion + decision making
-> lobotomy target

Question 20

Visual Association Area

Answer 20

interprets info thro primary visual cortex
MAKES SENSE OF WHAT YOU SEE

Question 21

difference between Motor + Sensory Homunculus

Answer 21

Motor homunculus = body parts + corresponding frontal lobe
sensory homunculus = body parts + corresponding w Parietal lobe

Question 22

Olfactory Bulb

Answer 22

sends smell info to the brain from nose
inferior of portion of frontal lobe

Question 23

Prosopagnosia

Answer 23

Disorder of facial features are unrecognizable
FACE BLINDNESS

Question 24

Fissure

Answer 24

deep groove dividing large regions brain regions

Question 25

Hemineglect

Answer 25

condition where a person neglects 1/2 of their body / food or drawings damage affects opposite side of the body

Question 26

somatosensory association cortex

Answer 26

integration + interpretation of sensations hand-> eye coordination

Question 27

Cortical deafness

Answer 27

auditory disorder sounds aren’t processed - can be heard

Question 28

phantom pain

Answer 28

occurs after amputation 60-80% feel as though everything is normal

Question 29

primary visual cortex

Answer 29

processes visual info relayed by the brain

Question 30

wernicke’s aphasia

Answer 30

impaired language comprehension but speech is normal

Question 31

primary motor cortex

Answer 31

involved w bodily movements neurons pmc spine muscles

Question 32

(limbic system) Cingulate Gyrus

Answer 32

regulates emotions + pain, fear + prediction of regulate consequences. above and around carpus callosum

Question 33

Aphasia

Answer 33

the inability to understand or produce speech due to damage to the brain.
