Recently scientists have discovered a new region of the brain found in primates and higher species that has been named the locus motivatius.
Functional MRI studies have shown that this area at intersection of the occipital, temporal and parietal lobes is chronically underdeveloped in the interlopers, the malcontents and the miscreants of the world. But perhaps more interesting is the transient loss of function recently seen by researchers in the United States.
Recently, it has been demonstrated that accute, short term lesions of the locus motivatius are a common occurence around the months of April and May in students of all ages. Symptoms include: lethargy, time wasting, tv watching, and blog posting.
There are no known treatments, but often times symtoms spontaneously resolve with the onset of "warmer weather" or the conclusion of all required classwork for the year.
