Q

What is the part of white matter

A

Bundles of fibers

18
Q

What is the function of bundles of fibers

A

Connect different regions of the brain to communicate with each other and transfer information from one hemisphere to other by corpus callousness

19
Q

What is the brain function

A

1) sensory system ( monitor and reflex )
2) cognitive system ( voluntary response)
3) behavioural state system ( governs sleep wake cycle)

20
Q

Cerebral cortex is organized into functional Areas

A

1) sensory area
2) motor area
3) association areas

21
Q

Ce verbal lateralization

A

Right and left hemisphere has different functions

22
Q

The motor system governs output form CNS

A

1) skeletal muscle movement
2) neuroendocrine signals
3) visceral response

23
Q

What is the function of the behaviour state

A

Control levels of conciousness and sleep wake cycle

24
Q

Why do we sleep

A

Good for memory and immune response

25
Q

What are the 4 stages of sleep

A

N1 N2 N3 - non REM sleep
Rapid eye movement - REM sleep

26
Q

What is special about the N3 sleep

A

It is the feel sleep, it has a high amplitude and a low fréquency. During this phase the body positions is un conscious

27
Q

What is the REM sleep

A

Low amplitude high fréquence.
Brain activity inhibits motor neuron to skeletal Muscle paralysis and dream takes place

28
Q

One complete cycle takes how much time

A

1-2 h

29
Q

Primary clock

A

Located in the seprachiasmatic nucleus of hypothalamus

30
Q

What is the 2 functions of learning

A

Associative learning and non associative learning

31
Q

Explain associative learning

A

Occurs when 2 stimulus are associated with each other

32
Q

What is non associative learning

A

change in behaviour after repeated exposure to a single stimulus

33
Q

What is the 2 parts of non associative learning

A

Habituation and sensitization

34
Q

Explain habituation or non associative learning

A

Habituation is that you have a lower réponse to an irrelevant stimulus that is repeated over and over again

35
Q

Explain sensitization of non associative learning

A

Exposure to noxious or intense stimulus causes an enhanced response upon subsequent exposure

36
Q

What is memory

A

Ability to retain and recall information

37
Q

What is short term, working memory and long term memory

A

Short term: memory disappears eight away unless an effort is made
Working memory : it keeps information long enough to put them in use in a task
Long term memory : capable of holding a vast amount of information

38
Q

What is long term memory with consolidation

A

Process that converts short memory into a long term one

39
Q

What is reflexive memory and declarative memory

A

Reflexive : automatic does not require conscious attention
Declarative : require attention to recall

40
Q

Spoken language involves 2 regions

A

Wernicks area - understand language
Broca’s area - produce speech
