SCANNING TECHNIQUES


Functional Magnetic Resonance Imaging -Indirectly measures electrical activity of neurons by recording changes in brain blood flow while a person completes a task.

+A strength of fMRI is its high spatial resolution
-A limitation of fMRI is its low temporal resolution.


Electroencephalogram-Directly and continually measures general electrical activity of neurons during brain states such as sleep and arousal.

+A strength of using an EEG is its high temporal resolution.
-A limitation of using an EEG is its low spatial resolution.


Event-Related Potentials-ERPs are very small changes in electrical activity of the brain that are elicited by specific stimuli presented to the participant (e.g. a picture).

+A strength of using ERPs is their high temporal resolution
-A limitation of using ERPs is they only detect activity in the superficial layer


POST-MORTEM EXAMINATIONS

• analysis of a person’s brain after their death

+A strength of post-mortem examinations is they investigate deeper areas of the brain

-One limitation using post-mortem examinations is the post-mortem delay
-struggle with issue of causation

Usually this forum is to ask questions about something you aren't sure of related to a subject, but you've just put some information on ways you can look at the brain

If you scroll to the top of the page, just above your title for the thread it tells you (starts 'My TSR ->')

If a thread is in the wrong place, you can report it to be moved (on the right side of the screen on each post), although this is the most appropriate forum for this as it is about the subject
