23
Q

Acetylcholine

A

voluntary motor control, attention, learning, sleeping, dreaming, memory

24
Q

Dopamine

A

emotional arousal, pleasure reward and voluntary movement

25
Q

Serotonin

A

sleep/wakefulness, aggression, pain and mood regulation

26
Q

endorphins

A

dulls pain and elevates mood

27
Q

Somatic NS

A

Part of peripheral NS, involved in voluntary and involuntary actions

28
Q

Autonomic NS

A

Part of peripheral NS, conveys info to and from the internal body structures that support basic life functions

29
Q

Sympathetic

A

Component of Autonomic NS, responds to emergency, stops digestion and increases heart rate

30
Q

Parasympathetic

A

Involved in routine activities, regulates blood sugar and heart rate

31
Q

Reflexes

A

Part of CNS, rapid automatic motor responses to sensory info

32
Q

EEG

A

Electroencephalography- Records electrical activity of many neuron’s

33
Q

MRI

A

Magnetic resonance imaging- studies brain anatomy

34
Q

FMRI

A

functional magnetic resonance imaging- studies brain function

35
Q

TMS

A

Transcranial magnetic simulation- Creates magnetic field and interrupts brain processing

36
Q

Hindbrain

A

controls basic functions of life
e.g respiration, heart rate

37
Q

Midbrain

A

Help orient us in the environment- regulates sleep and wakelfulness

38
Q

Forebrain

A

The part that does the most cognition

39
Q

Thalamus

A

Processes sensory information and sends it to different regions of the brain

40
Q

Hypothalamus

A

responsible for fleeing, fighting, feeding and fucking

41
Q

Amygdala

A

Responsible for emotional processing

42
Q

Limbic system

A

Hypothalamus, amygdala and hippocampus- help process motivation, emotion, learning and memory

43
Q

Hippocampus

A

creating and retrieving long term memories

44
Q

Basal ganglia

A

putamen, caudate nucleus and global pallidus- important for intentional movement

45
Q

Gyrus

A

bumps/ridges in the wrinkles of our brain

46
Q

Sulcus

A

grooves in the wrinkle of our brain

47
Q

Lobes of the cerebral cortex

A

frontal, parietal, occipital and temporal lobe

48
Q

Primary areas

A

process raw sensory info and movement

49
Q

association areas

A

involved in more complex mental processes

50
Q

lateralisation

A

2 sides of the brain split into cerebral hemispheres

51
Q

Corpus callosum

A

connecting both sides of the brain for information crossover

52
Q

neuroplasticity

A

the brain is plastic which means it can change and rewire itself

53
Q

phantom limb syndrome

A

long after a limb has been amputated someone might experience pain where the missing limb would be

54
Q

Neuogenesis

A

growth of new neurons
