Section 2

Question 1

Three methods of examining the cell

Answer 1

Staining (golgi stain and nissal stain)
electron microscopy
tract tracing

Question 2

What is Golgi stain?

Answer 2

only staining a few cells so that you can examine the structure of the full cell

Question 3

What is Nissal stain?

Answer 3

stains the soma of all cells

Question 4

Why might you use Nissal stain instead of Golgi Stain?

Answer 4

Nissal stain can be more useful when looking at degenerative disorders since you can see all the cells and examine which ones are degenerative

Question 5

Cerebral hemisphere

Answer 5

part of the telencephalon
process most functioning and cognitive functioning

Question 6

Thalamus

Answer 6

part of the diencephalon
composed of nuclei
structure that all the peripheral information passes through before reaching the spinal cord for processing

Question 7

Fiber bundles

Answer 7

cerebral commissures (separations between brain areas)

Question 8

What is the largest commissure in the brain?

Answer 8

the corpus callosum

Question 9

Which commissure separates the frontal and the parietal lobe?

Answer 9

central sulcus

Question 10

Insula (definition)

Answer 10

the structure that cannot be seen from the outside

Question 11

The nervous system is ___ segregated

Answer 11

functionally

Question 12

What are the four steps of sensory coding?

Answer 12

reception
transduction
coding
sensation, perception, and attention

Question 13

Reception (definition)

Answer 13

specialized cells called sensory receptors receive signal and respond to specific stimuli which is called reception

Question 14

Transduction (definition)

Answer 14

converting the external stimuli to a neural signal

Question 15

Coding (definition)

Answer 15

temporal patterns of the neural activity - helps us differentiate information by temporal and spatial features

Question 16

Sensation (definition)

Answer 16

process of detecting the presence of sensory stimuli

Question 17

Perception (definition)

Answer 17

cortical effects of the primary somatosensory cortex integrating, recognizing, and interpreting complete patterns of sensation

Question 18

Attention (definition)

Answer 18

the ability to concentrate of mental effort on sensory events

Question 19

Sense systems are _____ and ____ separated

Answer 19

functionally; anatomically

Question 20

Occipital lobe controls

Answer 20

visual

Question 21

Temporal lobe controls

Answer 21

Auditory

Question 22

Parietal lobe controls

Answer 22

somatosensory

Question 23

Pyriform cortex controls

Answer 23

olfactory

Question 24

Insula controls

Answer 24

Gustatory

Question 25

Direction of signal flow in sensory pathways

Answer 25

lower to higher order of info processing

Question 26

The specific order of signal flow is as follows

Answer 26

Receptor –> Thalamus –> Primary cortex –> Secondary Cortex –> Association Cortex

Question 27

Different pathways of information processing

Answer 27

hierarchical and parallel

Question 28

Hierachial

Answer 28

different levels of processing; basic level interacting with outside to complex internal processing
