Lesi sigaba sihlanganisa ndawonye izifundo ngobuciko obusebenzisa isekethe lomvuzo nakubuntu obufuna izinto ezintsha. Kungenzeka ukuhlobanisa izici ezithile zobuntu, njengokuxhamazela, nethuba elandayo lokuba nomlutha. Abazibeka engcupheni nalabo abanezinselelo zokulawula umfutho bakulesi sigaba. Zombili lezi zici zibonakala zihlobene nokukhululwa kwe-dopamine namazinga we-receptor. Abathatha ubungozi bakhipha i-dopamine eningi yokusha, futhi abantu ababonakala ngokungxama banamazinga aphansi ama-receptors e-dopamine (D2).
Lesi sigaba siqukethe zombili izindatshana ezibekiwe zomphakathi jikelele, nezindatshana zocwaningo. Uma ungeyena uchwepheshe wokulutha, ngiphakamisa ukuthi uqale ngama-athikili abekiwe. Baqala ngo- “L.”
