1

what functions are more dominant in the left hemisphere

language and maths

2

what functions are more dominant in the right hemisphere

body image, emotion and music

3

what functions are the frontal lobes involved in

motor, speech expression, cognition and eye movements

4

what functions are the parietal lobes involved in

sensory function but also speech comprehension, body image and calculation

5

what is the condition neglect

this is where you have damaged your parietal lobes and so body image is affected - it means you fail to acknowledge the left half of the world

6

what functions are the temporal lobes involved in

hearing, olfaction, memory and emotion

7

which hemisphere dominants in language pathways

left

8

describe the language pathway involved in repeating a heard word

- auditory cortex get information from the cochlea via vibrations
- information sent to wernickes area which translates the vibrations into words
- information sent to Broca's area via the arcuate fasciculus
- Broca's area projects onto lateral motor cortex to drive muscles used for speech

9

describe the language pathway involved in speaking a written word

- primary visual cortex in occipital lobe interprets written word
- information sent to wernickes area which translates the this into words
- information sent to Broca's area via the arcuate fasciculus
- Broca's area projects onto lateral motor cortex to drive muscles used for speech

10

describe the language pathway involved in speaking a thought

- areas from all over the brain sends information to wernickes area which translates the this into words
- information sent to Broca's area via the arcuate fasciculus
- Broca's area projects onto lateral motor cortex to drive muscles used for speech

11

what would result in damage to wernickes area

poor comprehension of language but can speak fluently

12

what would result in damage to Broca's area

good comprehension of language but cant speak fluently

13

define arousal

emotional state associated with a goal or avoidance of something

14

what is the reticular formation

a poorly defined region of grey matter made up of interneurones which helps to keep you conscious

15

name 3 relays involved in sending information from the reticular formation to the cortex

basal forebrain nucleus
hypothalamus
thalamus

16

what does the basal forebrain nucleus release to excite the cortex

ACh

17

what does the hypothalamus use to excite the cortex from the reticular formation

histamine

18

what does the thalamus use to excite the cortex from the reticular formation

glutamate

19

what happens to the reticular formation during sleep

it is deactivated

20

what is narcolepsy

where you struggle to stay awake due to problems in neurotransmission

21

what is sleep apnoea

where the soft tissue from the neck obstructs the airways, making you become hypoxic and wake up

22

what are the 2 types of memory

declarative (facts)
non-declarative (motor skills and emotion)

23

where are declarative memories stored

they are distributed throughout the cerebral cortex

24

where are non-declarative memories stored

in the cerebellum

25

on an EEG what do therein waves look like when your eyes are open

high frequency beta waves

26

on an EEG what do therein waves look like when your eyes are closed

alpha waves which are at a lower frequency and more synchronised

27

on an EEG what do therein waves look like in stage 1 of sleep

a background of alpha waves with some theta waves

28

on an EEG what do therein waves look like in stages 2/3 of sleep

background of theta waves
some k complexes (as the input from the cortex is removed so you get its intrinsic slow rate)
and sleep spindles (buzzes of activity from the thalamus trying to wake you up)

29

on an EEG what do therein waves look like in stage 4 of sleep

dominated by delta waves

30

on an EEG what do therein waves look like in REM

looks like beta waves as you are dreaming
