introduction to BBB

Question 1

what is somatic intervention?

Answer 1

manipulation of the brain to change behaviour e.g - using alcohol to reduce anxiety

Question 2

what is behavioural intervention?

Answer 2

manipulating behaviour to change the size of Brian areas e.g - London taxi drivers have a larger hippocampus

Question 3

what is correlation in the brain?

Answer 3

when the body and the Brian co-vary - parallel changes brain and behaviour e.g - OCD and serotonin

Question 4

outline levels of analysis

Answer 4

social level
- individual behaviour in social interaction
organ level
- brain, spinal cord, peripheral nerves and eyes
neural system
- eyes and visual brain registration
cellular level
- single neuron
synaptic level and molecular level

Question 5

BBB though the ages

Answer 5

Aristotle - brain to cool blood
Galen - head injuries modify behaviour
Descartes - dualism/ mind and body = behaviour
William James - consciousness and human experience/ nervous system
Donald Hebb - behaviour and neural function are correlated

Question 6

dualism

Answer 6

soul produces behaviour

Question 7

dualism (Descartes)

Answer 7

body and brain is a machine which produce breathing

Question 8

materialism

Answer 8

behaviour is produced by the nervous system

Question 9

function of the cerebellum

Answer 9

detects motor errors and improves them, dense with neurone and regulates balance and motor skills.
little tail at the bottom back of brain

Question 10

function of occipital lobe

Answer 10

visual signals from the retina, passes info onto the temporal lobe to co-ordinate recognition

Question 11

function of the frontal lobe

Answer 11

decision-making, personality, motor control, codes info from environment, ensure we only focus on relevant info

Question 12

function of parietal lobe

Answer 12

codes info from the environment e.g - taste, touch, temperature.

Question 13

function of temporal lobe

Answer 13

houses memories, language and emotion comprehension.
contains the hippocampus, Wernicke’s area.

Question 14

what is Wernicke’s area

Answer 14

allows us to comprehend language, when damaged means someone can not understand words

Question 15

what is Boroca’s area

Answer 15

speech production, when damaged can not produce

Question 16

what is an EEG

Answer 16

measures the electrical activity of the brain, during sleep, measures activity in response to a specific stimulus

Question 17

MRI scan

Answer 17

identifies different regions of the brain and nervous system

Question 18

FMRI

Answer 18

measures blood flow in the brain during mental activity, identify where brain activity occurs

Question 19

TMS

Answer 19

increases and decreases brain activity, establishing a role in different brain regions.

Question 20

outline the nervous system

Answer 20

nervous system
central nervous system - brain - spinal cord
peripheral nervous system - somatic nervous system - autonomic nervous system - enteric nervous system

Question 21

function of somatic nervous system

Answer 21

picks up info from the environment to send to the Brain to encourage movement.
afferent pathways - coming into the body
efferent pathways - coming out of the body

Question 22

how many cranial nerves do we have

Answer 22

12

Question 23

how many spinal nerves do we have

Answer 23

31

Question 24

function of the sympathetic nervous system

Answer 24

fight or flight
prepares body for action by increasing heart rate and blood pressure

Question 25

what is the function of the parasympathetic nervous system?

Answer 25

rest and digest
helps the body relax by decreasing heart rate and blood pressure, stimulating digestion

Question 26

main function of enteric nervous system

Answer 26

controls the gut
regulates digestion and helps control nutrient absorption

Question 27

function fo the corpus collosum

Answer 27

connects 2 hemispheres together so axons can pass through either hemisphere

Question 28

what does the basil ganglia do?

Answer 28

helps Wirth motor control, learning and memory
