Answer 5

temporal lobe. analysis of speech info.

Question 6

broca area

Answer 6

frontal lobe in left. Responsible for speech production.

Question 7

wernicke area

Answer 7

left temporal lobe. Responsible for language comprehension.

Question 8

2 functions of nervous system

Answer 8

1. process and respond to information to in the environment

2. coordinate the working of different organs and cells

Question 9

CNS

Answer 9

made up of brain and spinal cord.

Question 10

spinal cord

Answer 10

responsible for reflex actions

Question 11

PNS role

Answer 11

transmits messages via neurons to and from nervous system

Question 12

autonomic nervous system

Answer 12

governs vital functions in the body such as breathing

Question 13

somatic nervous system

Answer 13

governs muscle movement and recieves information from sensory receptors.

Question 14

endocrine system

Answer 14

works alongside the NS to control vital functions through hormones. hormones are secreted into the bloodstream and affect any cell in the body that has a receptor

Question 15

thyroxine is produced by what galnd ?

Answer 15

thyroid

Question 16

pituaitary gland

Answer 16

master gland controls the release of hormones from other glands in the body.

Question 17

fight of flight

Answer 17

stressor recieved and activates the pituitary. Sympathetic system now aroused. Adrenaline is released from medulla into blood stream and causes changes in organs. Increase HR + dilation of pupils + reduced saliva production. Then parasympathetic brings it down. Resting state

Question 18

sensory neuron

Answer 18

long dendrites short axons. Transmit messages from CNS to PNS.

Question 19

relay neuron

Answer 19

short dendrites short axons. Connect sensory neurons to motor neurons.

Question 20

motor neuron

Answer 20

short dendrites long axons. Connect CNS to effectors such as muscles.

Question 21

lateralisation

Answer 21

The idea that the two halves of the brain are functionally different and certain behaviours are controlled by one side of brain.

Question 22

Left hemisphere lateralisation

Answer 22

language Broca- frontal wernicke- temporal

Question 23

brain is crosswired

Answer 23

right hemisphere controls movement on left side of body and left hemisphere controls movement on right side. And vision left visual field send info to right visual cortex and vice versa.

Question 24

hemisphere connected to left visual field of both eyes

Answer 24

left visual field of both eyes connected to right hemisphere

Question 25

hemisphere connected to right visual field of both eyes

Answer 25

right visual field of both eyes connected to left

Question 26

split brain definition

Answer 26

two hemispheres surgically separated by cutting the connections. Used to treat severe epilepsy.

Question 27

SPERRY split brain procedure

Answer 27

studied split brain ps. Image/word projected to RVF processed by LH and sam/diff image/word to LVF processed by right

Question 28

SPERRY FINDINGS

Answer 28

Objects shown to RVF can be described but when shown to LVF cant name object but can select matching object behind screen.

Question 29

plasticity

Answer 29

Brains tendency to adapt/change as a result to new learning.

Question 30

pruning

Answer 30

as we age barely used connections are deleted and used are strengthened.

Question 31

plastcity support study

Answer 31

maguire found significantly more volume of grey matter in hippocampus of cab drivers than control group. Linked with spatial and navigation skills.

Question 32

plasticity draganski

Answer 32

imaged brains of medical students three months before and after final exams.Changes seen in hippocampus and parietal cortex.

Question 33

functional recoveryy definition

Answer 33

following damage brain redistributes or transfers function usually performed by damaged areas to other ones.

Question 34

axonal sprouting

Answer 34

growth of new nerve ending which connect with other undamaged cells to form new neuroscience

Question 35

denervation supersentivity

Answer 35

axons that do a similar job become aroused to a higher level to conpensate for the oned lost

Question 36

recruitment of homologous areas

Answer 36

the opposite side of the brain takes over specific tasks

Question 37

FMRI

Answer 37

detects changes in both blood oxygenation and flow that occur due to neural activity in specific brain area. As when a brain area is active more blood goes there.

Question 38

EEG

Answer 38

measures electrical activity via electrodes using a skull cap. The scan represents brainwave patterns generated from neurons.

Question 39

ERP

Answer 39

what is left when brain activity from an eeg recording filters out. Using statistical technique leaving only responses related to presentation of specific stimulus.

Question 40

Post mortem examinations

Answer 40

examined to establish cause of disorder may involve comparison.

Question 41

role of somatic nervous system

Answer 41

transmits sensory information from body receptors to brain and brain to effectors to produce movement.

Question 42

inhibitory synaptic transmission

Answer 42

stimulation of postsynaptic receptors by inhibitory neurotransmitter result in inhibition of post synaptic membrane. If inhibitory inputs are higher than excitatory they inhibit action potential.

Question 43

FMRI

Answer 43

measure changes in blood oxygenation as a measure of neural activity - poor temporal resolution - good spatial resolution - non invasive

Question 44

ERP

Answer 44

- measure electrical activity via electrodes to detect brainwaves triggered by certain events - good temporal but poor spatial resolution

Question 45

split brain had ... severed

Answer 45

corpus callosum

Question 46

role of endocrine system

Answer 46

releases hormone from gland into bloodstream that bind to receptors in order to regulate activity of cells
