not elaborated upon in man-more developed in lower species

supcollic-visual reflexes
infcollic-auditory reflexes

Front 11

Hindbrain(rhombencephalon)

Back 11

metencephalon- cerebellum, pons

myelencephalon-medulla, SC

Front 12

Limbic Lobe

Back 12

border b/w Telenceph and Diencph
Telencephalic structures

1. amygdala
2. hippocampus
3. cingulate gyrus
4. HC gyrus

Front 13

what does the limbic lobe develop?

Back 13

1. emotions and memory
2. our response to dfft emotional stimuli
3. sexual preferences
4. eating preferences
5. dvlp out emotions

Front 14

what does the limbic lobe primarily receive?

Back 14

olfactory impulses

only impulse that terminates directly into the telencephalon

Front 15

central sulcus

Back 15

separates frontal from parietal

Front 16

2 primary functions of the frontal lobe

Back 16

1. motor cortex
2. original thought

Front 17

Precentral Gyrus

Back 17

Primary motor cotrex
Area 4
CST

Front 18

3 Subdivisions of Inferior frontal gyrus

Back 18

1. pars opercularis
2. pars triangularis
3. pars orbitalis

Front 19

lobes that have opercular areas

Back 19

frontal, temporal, parietal

all turn inward to insular cortex

Front 20

Brocas Speech Area

Back 20

just in front of the base of the precentral gyrus

areas 44 and 45

ability to learn how to speak

Front 21

what happens if brocas area is cut off?

Back 21

muscles of the larynx/pharynx will loose motor associations but will NOT be paralyzed

Front 22

Prefrontal Cortex

Back 22

ant to primary motor cortex
most developed in Man
Original Thought

creative/abstract thought

Front 23

Long Association Bundles

Back 23

connect prefrontal cortex to all other areas of CNS

Front 24

Postcentral Gyrus

Back 24

sensory association cortex
helps to understand external environment

Front 25

hemineglect

Back 25

damage to post central gyrus (sensory cortex)

Front 26

Temporal Lobe

Back 26

ant-post-and heschel's gyrus
auditory impulses come into context here (41+42)

Front 27

Receptive aphasia

Back 27

loose areas 21+22 in auditory association cortex

cant understand what is being spoken

Front 28

Expressive Aphasia

Back 28

loosing Brokas area

Front 29

Alzheimer's

Back 29

disease of association cortex

symptoms of profound dementia are from the association cortex

Front 30

Corpus collosum

Back 30

connects the 2 hemispheres

can be separated and still perfom well

Front 31

cingulate gyrus

Back 31

part of limbic lobe
necessary in laying down new memories

Front 32

Lamina Terminalis

Back 32

connects the anterior commissure to the optic chiasma

Front 33

what does the lamina terminalis represent?

Back 33

the closure of the ant neuropore

Front 34

Posterior Commissure

Back 34

interconnects areas on either side of the sup collic called the PRETECTAL NUCLEI
-visual relfexes(pupil constriction)

Front 35

Dorsal Longitudinal Fasiculus

Back 35

relays impulses from the hypothalmus down to the brainstem

Front 36

subcallosal gyrus

paraolfactory area of broca

Back 36

receiving olfactory impulses

rec olfact sensations

Front 37

Fornix


precommissural fornix

originates lateraly in temp lobe
concerned with memory formation
terminates in mammillary bodies

part of fornix that passes anteriorly

Front 38

Front 39
