the peak amount of pressure during heart contraction

Question 4

Diastolic Pressure

Answer 4

pressure maintained between heart beats

he number of heartbeats per unit of time. Usually heart rate is expressed as beats per minute

Question 11

Heart Rate variability

Answer 11

consistency of time between heart beats, duration of interest interval

Question 12

Measuring Respiration and uses

Answer 12

Measure breathing often used with cardio measures measuring workload

Question 13

Respiratory Sinus Arrhythmia (RSA)

Answer 13

naturally occurring variations in heart rate that occur during breathing cycle

Question 14

Skin Conductance Response

Answer 14

use of the skin to conduct electricity which is based on physiological arousal

Question 15

uses for EDR

Answer 15

• biofeedback for treating stress and anxiety
• measures stress and workload
• polygraph test

Question 16

biofeedback

Answer 16

technique that trains people to improve their health by controlling certain bodily processes that normally happen involuntarily, such as heart rate, blood pressure, muscle tension, and skin temperature.

Question 17

Electromyography (EMG)

Answer 17

procedure for measuring muscle tension

Question 18

uses for EMG

Answer 18

• look at indications of stress
• diagnostics of injury
• measure muscle fatigue

Question 19

neuropathy

Answer 19

disease or dysfunction of one or more peripheral nerves typically causing numbness or weakness

Question 20

myopathy

Answer 20

a disease of muscle tissue

Question 21

Pupillometry

Answer 21

measuring pupil diameter

• cannot be consciously controlled
• neurological evaluation
• drug testing

Question 22

Pupil reactivity under influence of drugs vs. clean

Answer 22

Pupils are dilated when on drugs

Question 23

Electrooculography (EOG)

Answer 23

Measures eye movement
Uses: -the filter eye movement artifacts from deg
evaluation of vestibular (balance) disorders
eye trackers
biofeedback

Question 24

Electroencephalography (EEG)

Answer 24

provides a gross measure if the electrical activity/signals of the brain (overall general activity in a cortex)

Question 25

Prepping EEG

Answer 25

separate hair and place electrodes on hair follicles

Question 26

10-20 System of Electrode Placement

Answer 26

the physical measurements for placing electrodes

Question 27

Nasion

Answer 27

the intersection of the frontal bone and two nasal bones of the human skull

Question 28

Inion

Answer 28

the projecting part of the occipital bone at the base of the skull.

Question 29

Uses of EEG

Answer 29

rules out disorders such asseizure disorders, including epilepsy
head injury
encephalitis, or inflammation of the brain
brain tumor
encephalopathy, or brain dysfunction resulting from various causes
memory problems
stroke
sleep disorders

Question 30

Pros and Cons of EEG

Answer 30

Pros: Good temporal resolution (activity with millisecond precision)

Cons: Poor spatial resolution (identifying where the activity is coming fron on/in the brain is not very precise)

Question 31

Causes of Artifacts

Answer 31

many things

Question 32

Magnetoencephalography (MEG)

Answer 32

a non-invasive technique for investigating human brain activity. It allows the measurement of ongoing brain activity on a millisecond-by-millisecond basis, and it shows where in the brain activity is produced.
