Chapter 1

Question 1

first principle of neuroscience: Interconnectivity

every part of the nervous system is ?

and because of this, messages from one area of the brain can ?

Answer 1

interconnected through fibers

• association
• commissural

trigger responses from many other regions of the brain

Question 2

Centrality

the central nervous system is?

everything is connected through?

the brain is the ?

Answer 2

central

CNS

Boss

Question 3

principle three: laterality

bilateral?

unilateral?

contralateral?

Answer 3

anatomic symmetry:
hemispheres near mirror images

function asymmetry: each hemisphere has different functions

sensorimotor control: motor and sensory functions are controlled by opposite side of the brain

Question 4

Functional Networks:
sensory and motor systems have ?

each pathway carries specific?
this is especially advantageous as these ?

Answer 4

specialized cells that carry out each systems function

types of messages/ specialized cells and their perceptions can be more adaptable and faster

Question 5

Topograpical org.:

cells are arranged in the brain according to ?

Answer 5

body’s spatial org.

Question 6

Plasiticty: the brain changes?

in fact, brain cells?

Answer 6

experience (LEARNING)

reorganize their functional capacity

Question 7

Culturally neutral:

despite individual variability across all humans, brain function unaffected by?

Answer 7

sex, race, brain size shape or weight

Question 8

CNS:

-connects to ?
outside?

Answer 8

brain
spinal cord
inside skull and vertebrae

nerves and ganglia outside of the brain and spinal cord (including cranial and spinal nerves)

• muscles, glands, and organs
• skull and vertebra
• somatic and autonomic nervous system

Question 9

Cerebral Cortex: … thick layer of ? covers the entire surface of ?

pyramidal: most ? located in ? not ?
- only cells whose ?

granular/satellite: local? cons project to ?

interneurons:

how many layers in neocortex
-responsible for ?

different regions with ?

Answer 9

3-5mm/ gray matter (cell bodies) / cerebrum

• common/ 5 of 6 layers/ molecular
• outgoing axons project to adjacent association cortex and connect with subcortical structures, spinal cord, and basal ganglia

association cells; facilitate or inhibit local circuitry

6 layers
-higher level mental and sensorimotor functions

varied cellular configurations
