Biopsychology

Question 1

Brain

Answer 1

• cerebral cortex
• limbic system
• medulla

Question 2

cerebral cortex

Answer 2

• frontal lobe
• parietal lobe
• Occipital lobe
• temporal lobe

Question 3

frontal lobe

Answer 3

• prefrontal cortex = personality
• motor cortex = generate signal for voluntary movements
• Broca’s Area = speech production

Question 4

parietal lobe

Answer 4

• somatosensory cortex = receive sensory infomation

Question 5

Occipital lobe

Answer 5

• primary visual cortex = receive visual info

- visual associative cortex = analyse visual to form images

Question 6

Temporal lobe

Answer 6

• primary auditorial cortex = receive sound info
• Auditorial associative cortex = analyse sound info and generate audio
• Wernicke’s Area = speech conprehension

Question 7

Limbic system

Answer 7

Thalamus = relay sensory info 
Hypothalamus = internal coordination (hunger, thirst)
Hippocampus = memory
Amygdala = emotion

Question 8

Medulla

Answer 8

= automatic function

• Pons = sleep
• Cerebellum = regulate movement
• Brain stem = basic (heartbeat, breathe)

Question 9

Neuron types

Answer 9

• sensory neuron (sensory to CNS)
• interneuron
• motor neuron (CNS to motor)

Question 10

neuron structure

Answer 10

• dendrites
• soma = nucleus + cytoplasm
• myelin sheath (Schwann cell = PNS; oligodendrocyte = CNS)
• terminal button
• synapses

Question 11

synapse

Answer 11

• synaptic cleft
• neurotransmitter (chemical messengers)
• receptors

Question 12

neurotransmitter

Answer 12

Acetylcholine = vital fro basic function
Dopamine = happiness, relaxation
Seretonin

Question 13

Agonist vs Antagonist

Answer 13

Agonist = mimicking effect
Antagonist = blocking receptor (e.g, Curare block Ach receptor)

Question 14

Inhibitory vs Excitatory

Answer 14

Inhibitory = inhibit the likelihood of aneural activity to fire
e.g., dopamine & serotonin

Excitatory = encourage the likelihood of neural activity to occur
e.g., Acytlcholine

Question 15

Fodorism

Answer 15

• the idea that there is one-to-one match between brain and behavior
  e. g., Functional specialisation

Question 16

Neuron system

Answer 16

Central NS = brain + spine
Peripheral NS :
-- automatic NS :
  * sympathetic = fight or flight
  * parasympathetic = relax and digest
-- somatic NS
  * sensory = input
  * motor = output

Question 17

neuron potential

Answer 17

• resting potential = -77 mV
  threshold = -55 mV
• acting potential = 40 mV
• All-or-none principle

Question 18

All-or-none principle

Answer 18

neuron activity: either complete or none\

- depending whether threshold is reached

Question 19

process of potential

Answer 19

depolarisation = Na+ enter
Depolarisation = K+ out
hyperpolarisation

Question 20

Methods studying brain

Answer 20

CT scan = using X-ray
EET = metal discs attached to scull
PET = inject/swallow/inhale tracer
MRI = nuclei resonance
fMRL = oxygen level

Question 21

Mirror neurons

Answer 21

= groups of neurons that are activated when observing others’ behaviour or action
- explain social learning theory
