shortcuts for intuitive responses

29
Q

what parts of the forebrain supports emotions, learning and movement?

A

limbic system and basal ganglia

30
Q

what does basal ganglia mean

A

bottom and clump of cell bodies

31
Q

gyrus/gyri means..

A

bump

32
Q

sulcus/sulci means…

A

crack

33
Q

longitudinal fissure

A

separates left and right parts of the brain

34
Q

part of brain with internal map

A

parietal lobe

35
Q

contact mediated attraction/contact mediated repulsion

A

how cells move toward/ move away from certain things

36
Q

whats the first stage of wiring the brain

A

generation of neurons from the neural tube

37
Q

steps of wiring the brain

A

neurogenesis
migration
differentiation

38
Q

what trimester does neurogenesis occur

A

first trimester

39
Q

what trimester does cell differentiation happen

A

second

40
Q

what trimester does neuronal maturation happen

A

third

41
Q

why is there so much neurogenesis happen in first trimester

A

an increase in human growth factor

42
Q

stages of cell types/maturation

A

stem
progenitor
blast
specialized

43
Q

two types of blast cells

A

neural and glial

44
Q

arboration

A

when neurons are trying to connect to ll cells (arborize-uncontrolled growth)

45
Q

what predisposes cells to migrate to certain cortical locations

A

subvascular zone

46
Q

what distinctly differentiates the cortex’s cellular makeup?

A

organized into layers and grows off of subvacular zone

47
Q

what acts like a scaffold for new neurons

A

glial

48
Q

ventricles are what part of the brain?

A

the empty spaces

49
Q

what happens during further differentiation

A

when cells reach their destination they go from precursor to neuron

they extend their axons to find appropriate target

50
Q

what begins differentiation

A

neurites sprouting off cell body

51
Q

when is the neurons fate determined

A

before migration

52
Q

what does architecture depend on

A

intercellular signals

53
Q

optic chiasm

A

where neurons cross left and right eyes

54
Q

steps of making connections

A

pathway selection
target selection
address selection

55
Q

axons and dendritic process appear_____

A

similar. they are both called neurites in cell differentiation

56
Q

what is the growing tip called

A

growth cone

57
Q

what did hubel and wiesel work on (and got nobel prize)

A

ocular dominance (whether neurons go to contralateral vs ipsilateral) it showed how cats only respond to certain angels/placements depending on what they were exposed to during the critical period

58
Q

od

A

right eye

59
Q

os

A

left eye

60
Q

when do we become accustomed to new angles

A

critical period/critical wiring

61
Q

motor visual recalibrations

A

adjusting speed of walking to make vision go at certain speed

62
Q

synapse formation in cna steps

A

Q

booba vs keke is based off of..

A

acceleration in TPJ

65
Q

basis of synesthesia is located in..

A

temporal partiaa junction

66
Q

steps of brain plasticy

A

arborization
pruning
(neurons that fire together wire together)

67
Q

what parts of the brain myelinate last

A

frontal

parietal

68
Q

Basic organization plan of CNS of call mammals

A
Telencephalon
Diencephalon (thalamus)
Midbrain
