Scientists have discovered that the body heals some lesions naturally by stimulating oligodendrocytes in the area — or by recruiting young oligodendrocytes from further away — to begin making new myelin at the damaged site. However, this natural repair process is slow and incomplete. Scientists are investigating several different strategies for stimulating the repair of myelin , including testing existing drugs , finding ways to stimulate oligodendrocytes to produce myelin, and ways to protect oligodendrocytes and myelin from further damage.
It is also known that the nontrivial zeros are symmetrically placed about the critical line , a result which follows from the functional equation and the symmetry about the line . For if is a nontrivial zero, then is also a zero (by the functional equation), and then is another zero. But and are symmetrically placed about the line , since , and if , then . The Riemann hypothesis is equivalent to , where is the de Bruijn-Newman constant (Csordas et al. 1994). It is also equivalent to the assertion that for some constant ,
