Individual patient sensitivity to pain and analgesia
Research endeavors focus on the discovery and validation of subject-specific
attributes that determine vulnerability for greater than average impact of
pain in terms of sensory, affective, endocrine and autonomic functions.
Understanding of the biological response patterns that determine worst
outcomes associated with suffering persistent pain are highly desirable. If
known, subjects at risk could be identified and treatment targets for
reducing subject-specific vulnerability be devised.

Neonatal analgesic mechanisms
Gustatory and orotactile stimulation in neonates access endogenous analgesic
systems and lead to pain relieving and calming effects. These effects appear
mediated by brain stem descending pathways involving opioid and
monoaminergic systems. Understanding these mechanisms will lead to new
analgesic strategies in newborns.

Neuroimaging pain
Multiple parallel sites in the cerebrum are activated by pain and help
define the sensory, attentional, motivational and cognitive components of
the experience. Functional neuroimaging of the brain is now being used as a
physiological index of the experience of pain. Such imaging identifies
aberrant brain functioning that occurs in pathological conditions of
persistent pain and indicates individual differences in the response to
analgesics. There are variations in the brain’s response to painful events
that are related to the sex and the hormonal status of the individual. The
future holds promise for targeting treatment based on imaging of the brain
during pain and analgesia.
