Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What term describes the duration between brain activity occurring, and this being shown on a scan?
A
Non-invasive
B
Spatial resolution
C
Temporal resolution
D
None of the above
Explanation: 

Detailed explanation-1: -Temporal resolution refers to the accuracy of the scanner in relation of time: or how quickly the scanner can detect changes in brain activity. fMRI scans have a temporal resolution of 1-4 seconds which is worse than other techniques (e.g. EEG/ERP which have a temporal resolution of 1-10 milliseconds).

Detailed explanation-2: -Definition. Temporal resolution is defined as the amount of time needed to revisit and acquire data for the exact same location. When applied to remote sensing, this amount of time depends on the orbital characteristics of the sensor platform as well as sensor characteristics.

Detailed explanation-3: -In a nutshell, spatial resolution refers to the capacity a technique has to tell you exactly which area of the brain is active, while temporal resolution describes its ability to tell you exactly when the activation happened.

Detailed explanation-4: -Temporal resolution relates to the duration of time for acquisition of a single frame of a dynamic process, i.e., cine imaging.
