psychophysiological methods in neuroscience

Question 1

sMRI

Answer 1

structural magnetic resonance imaging

• noninvasive; view anatomical structures
• magnetic field causes atoms to line up in same direction
• measures energy in form of electromagnetic radiation
• used to compare size of structures

Question 2

MEG

Answer 2

magnetoencephalography

• noninvasive
• measures electrical current associated with neural activity (weak magnetic field)
• high temporal resolution
• more expensive; less available

Question 3

SNS

Answer 3

sympathetic nervous system

• controls sweat glands
• increase in skin conductance can be associated with changes in psychological activity
• allows researchers to see whether psychopaths react to fearful pictures in normal way

Question 4

PNS

Answer 4

parasympathetic nervous system
- innervates cardiovascular measures
SNS increases HR and PNS decreases HR

Question 5

electrocardiogram

Answer 5

measures HR

Question 6

EMG

Answer 6

electromyography

• measures activity of skeletal muscles
• has been used in emotion research, identifying activity in muscles used to produce smiles
• high temporal resolution
