Answers |Latest 2025 | Guaranteed Pass.
Which is NOT a neuroimaging technique mentioned in the text? - Answer✔Nuclear magnetic
resonance (NMR) spectroscopy
What is the name of a recently developed technique that uses fine-grained fMRI images to
study combinations of activations across disparate small regions of the brain? -
Answer✔pattern classification
Which neuroimaging technique was banned by some local governments who regarded it as
psuedoscience? - Answer✔phrenonology
Tovino thinks we should seriously consider a complete ban on functional neuroimaging (fMRI). -
Answer✔False
What do all of the following have in common according to Tovino?
phrenology, x-ray, PET, SPECT, fMRI - Answer✔All were introduced in the name of science, but
quickly became commercialized.
Neuroimaging technology - Answer✔EEG, PET, fMRI
EEG(electroencephalogram) method - Answer✔-spiking neurons create electrical signals
-electrodes on skull detect signal
-mental events can be identified by patterns of electrical activity
EEG event related potential - Answer✔novelty response
EEG strengths - Answer✔-very good temporal resolution
-non-invasive
-cheap & portable
EEG weaknesses - Answer✔-poor spatial resolution

-only measures activities in more exterior portions of the brain
-"noisy"
PET(positron emission tomography) method - Answer✔-introduce radioactive tracer to
bloodstream
-beta decay-gamma rays
-these are detected by the detector and a 3D image is generated.
-more activity-more blood flow-more tracer
PET strengths - Answer✔-good spatial resolution
-allows good insight into brain function
-quick & easy
PET weaknesses - Answer✔-poor temporal resolution
-limited time before the tracer decays
-invasive
fMRI(functional magnetic resonance imaging) method - Answer✔-similar to PET, but w/o the
exogenous tracer.
-uses MR to detect oxygenated hemoglobin (BOLD signal)
-indirectly measures activity level(spiking)
fMRI strengths - Answer✔-good spatial resolution (1-6 cubic mm, a few million neurons)
-non-invasive
-allows for study of the entire functional network of the brain
fMRI weaknesses - Answer✔-low temporal resolution
-BOLD signal is an indirect measure of brain activity
uses of neuroimaging - Answer✔-clinical
-non-clinical
-commercial
-legal
-government
non-clinical uses of neuroimaging - Answer✔-personality
-mental illness
