Flashcards in functional organization of the cerebral cortex Deck (25):
0

1,2,3

Primary somatosensory area for touch, pressure, vibration, itch, tickle, temperature, pain, proprioception
post central gyrus
cross over

1

4

Primary motor area (in precentral gyrus)
motor homunculus

2

5,7

somatosensory association area, receives input from the primary somatosensory area, thalamus and other areas (presents)

3

6

premotor area, communicates with primary motor cortex, sensory association areas, basal nuclei and thalamus
leaned motor activities of a complex and sequential nature

4

8

frontal eye field area
Voluntary scanning of eyes, eye movement to follow lines

5

9,10, 11, 12

Prefrontal cortex
personality, intellect, complex learning abilities, recall of information, planning for the future, abstract idea, conscience

6

11

orbitofrontal cortex
receives sensory impulses from the primary olfactory area
allows you to identify odors and discriminate among different odors
more dominant on the RIGHT!

7

17

Primary visual area
Receives visual information and involved in visual perception

8

18, 19

Receives sensory impulses from the primary visual area and thalamus, relates present and past visual experiences
is essential for recognizing and evaluating what is seen

9

20, 21, 37

Facial recognition area
receives impulses from the visual association area, more dominant on right

10

22

auditory association area
lets you recognize a particular sounds as speech, music or noise

11

22, 39, 40

Wernicke's area
Interprets meaning of speech by recognizing spoken words more dominant on LEFT. Left for Language

12

5, 7, 39, 40

Common integrative area
Receives nerve impulses form primary sensory areas, thalamus and parts of brainstem

13

41, 42

Primary auditory area
Receives visual information and involved in auditory perception

14

43

Primary gustatory area
Receives impulse for taste and Invovled in gustatory perception and taste discrimination

15

44, 45

Broca's speech area
In 97% of people it's located in the left hemisphere
impulse is going to premotor areas that control speech muscles and to primary motor area

16

aphasia

inability to use or comprehend words

17

non fluent aphasia

damage to Broca's area
inability to properly articulate or form words
know what they want to say but can't say it

18

Fluent aphasia

damage to Wernicke's common integrative area or auditory association area
faulty understanding of spoken or written words
word salad - trings of words with no meaning (dementia)

19

Left Hemispheric

Language (spoken, written, sign language)
Logic
Scientific skill
math
reasoning
numerical

20

Right hemispheric

Creativity
musical
artistic
facial recognition
discrimination of difference
generating images
sight, smell, sounds, etc

21

Beta waves

14-30Hz when the nervous system is active, sensory input, mental activity

22

Alpha waves

8-13 Hz awake but resting with eyes closed

23

Theta waves

4-7 Hz when experiencing emotional stress also in many disorders of the brain

24

Delta waves

1-5 Hz During deep sleep in adults and in normal awake infants
