Definition

Spatial resolution refers to how well an imaging technique can distinguish between different structures or regions in the brain. It indicates the level of detail and precision with which fine-scale features can be observed.

EEG (Electroencephalography): This non-invasive technique records electrical activity from electrodes placed on the scalp but has lower spatial resolution compared to other neuroimaging techniques.

CT Scan (Computed Tomography Scan): This method uses X-rays to produce cross-sectional images of the brain but has relatively lower spatial resolution than MRI.

High-resolution fMRI: An advanced version of fMRI that offers improved spatial resolution, allowing researchers to observe smaller brain structures and activity patterns.
