WEEK 10-LOCALIZATION OF HIGHER BRAIN FUCNTIONS

Question 1

true or false after neurogenensis the brain (for the most part) doesnt hav ethe capacity to form new neurons

Answer 1

true

Question 2

how does the brain regenerate

Answer 2

neuroplasticity

Question 3

what are the different forms of plasticity

Answer 3

short temr
long temr

Question 4

neuroplasticity is done through

Answer 4

synaptic plasticity

Question 5

what is short term plasticity

Answer 5

affects pre-synaptic
neurotransmitter release)

Question 6

what is long term plasticity

Answer 6

(molecular mechanisms that vary over time)

Question 7

plasticity is important for what 3 things

Answer 7

memory
learning
rehab

Question 8

what is neuroplasticity

Answer 8

The ability of the nervous system to respond to intrinsic and extrinsic stimuli by reorganizing its structure, function and connections.

Neuroplasticity: How Experience Changes the Brain
Plasticity refers to the brain’s malleability or ability to change; it does not imply that the brain is plastic. Neuro refers to neurons, the nerve cells that are the building blocks of the brain and nervous system. Thus, neuroplasticity allows nerve cells to change or adjust.

Question 9

true or false for example in stroke the brain reorganizes itself in such a way to carry pout its functions

Answer 9

true

Question 10

what does pruning mean

Answer 10

losing synapses = we become more efficient

Question 11

how does the brain become more efficiceint

Answer 11

1. gros new connections
2. maximizing connection between 2 ceklls

Question 12

what are the steps of of brain plasticity available to the young CNS

Answer 12

1) Growth of axons and dendrites

2) Pruning of branches

3) Creation of synapses

4) Death of neurons

5) Changes in synaptic strength (LTP)

Question 13

what is the result of brain plasticity in youh

Answer 13

Result: elaboration and fine tuning of the developing CNS

Question 14

neuroplasticity is imporant fir healthy development during

Answer 14

critical periods

Question 15

what is a critical period

Answer 15

Critical period is a maturational stage in the lifespan of an organism during which the nervous system is especially sensitive to certain environmental stimuli.

Question 16

explain the critical period + cat

Answer 16

proper input at proper time = eye didnt develop in that eye

Question 17

an example of critical period

Answer 17

soccer players dont play at the world cup[ if they started playing soccer tat 20 = started youn

Question 18

when does neuroplasticity take place

Answer 18

Changes in neural pathways and synapses
due to:
n changes in behavior, environment, thinking, emotions

learning

memory

Question 19

neuroplasticity role in learning

Answer 19

Activity-dependent plasticity plays a very large role in learning and in the ability to understand new things.
n Help to adapt an individual’s brain according to the relative amount of usage and functioning.

Question 20

what uis learning

Answer 20

Change in behavior that results from acquired knowledge about the world

Question 21

what is memory

Answer 21

Process by which that knowledge in encoded, stored and later retrieved

Question 22

what is the role of neuroplasticity in memory

Answer 22

Essential for the full functioning and independent survival of people and animals
n People & places n Language
n Motor skills
n Personal identity
