Answer:

Neuroimagining techniques are different methods used for examine the structure of the brain(structural Imagine), and for studying the functions of the brain parts(functional Imaging),

Explanation:

Example of structural Imaging techniques are;

Computer Axial tomography.

Diffuse optical imaging

Magnetic Resonance Imagine

Examples of Functional imaging are;

Functional Magnetic resonance imaging

Positron Emission Tomography

Cranial Ultrasound

Magnetoencephalography

The release of low energy radiations, and implants of different metals into the body which may not be effectively screened out is the major concern of these techniques.
