Different imaging techniques allow the analysis of macro- and microstructural analysis of brain structures. Other researchers use the electrical activity of brain to study brain-behaviour relationships.
However, the researchers do face the following practical issues:
• Temporal resolution (the fastness with which an image is obtained)
• Spatial resolution (the accuracy of localization of the image in the brain)
• The degree of invasiveness
Thus, the blanks can be filled with temporal resolutions; spatial resolution; degree of invasiveness.
