Machines used to view the brain
Cards in this deck (10)
- 1Galvanic Skin Response GSRMeasures amount of sweat
does this by analyzing how quickly a slight of electrical current passes through two points on the skin - 2Electromyography (EMG)measures muscle activity
Does this by estimating the electrical impulses of the muscles during contraction and relaxation. - 3Computerized Topography (CT Scan)Takes a high resolution x-ray picture of brain
(produces static picture) - 4Magnetic Resonance Imaging (MRI)Uses high radio frequency waves to get picture of brain
(produces static picture) - 5Electroencephalogram (EEG)Electrodes placed on scalp to monitor electrical activity of the brain.
EP or evoke potential
(when electrical activity is measured in response to a specific stimulus) - 6Positron Emission Tomography (PET Scan)Slightly radioactive glucose like substance is injected into brain and person is placed into a scanner
(active region use up more glucose than inactive ones) - 7Functional Magnetic Resonance imaging (fMRI)monitors brain activity by tracing blood oxygen levels in brain
most detailed - 8Problems with fMRItiming response
time intensive
expensive equipment
non independence error
time of day
nervousness of participants - 9non independence errorresearcher unintentionally bias their results by not independently selecting which brain areas correlate with certain variables
- 10Transcranial Magnetic Stimulation (TMS)brief electrical current passes through a coil placed on head
