Theories of motivation have been proposed by scholars since the beginning of the 20th century. In recent decades neuroscientists have attempted to find similar physiologic drivers of human motivation (at a cellular and molecular level) to attempt to describe what causes humans to behave in goal-directed activity. Newer non-invasive neuroimaging technologies such as Single Photon Emission CT Scanning (SPECT), Functional Magnetic Resonance Imaging (f-MRI), and Positron Emission Tomography (PET) have been adopted and implemented to study the anatomic regions of the brain involved in motivation related neural activity, and to image the neurotransmitters and their receptors activated during cognitive motivational goal-directed activity. Theories of human motivation proposed by early pioneers in the field are, indeed, more than just constructs, and can be supported, validated, and reproduced through newer brain imaging technologies such as PET scanning, SPECT and f-MRI.
