Suresh learned that the abilities may be related to adrenaline. Norepinephrine (also called noradrenaline) is a similar chemical in the body that is also a neurostimulator (chemical in the brain) released by the nervous system to stimulate the "fight or flight" response (aslo name-dropped by Suresh).
Perhaps Sylar is "studying" the part of the brain that kicks off this chemical process--the part that releases the hormone/adrenaline-like chemical that is involved in triggering fight-or-flight--which triggers the abilities.
