The widespread convergence of information from visceral, cutaneous, and muscle tissues
onto CNS neurons invites the question of how to identify pain as being from the viscera …

Visceral and somatic pain perception differs in several aspects: poor localization of visceral
pain and the ability of visceral pain to be referred to somatic structures. The perception of …

Different pain types may be encoded in different brain circuits. Here, we examine similarities
and differences in brain processing of visceral and somatic pain. We analyze data from …

Clinical evidence suggests that cutaneous and visceral pain differ in sensory, affective, and
motivational realms, yet there has been little comparative characterization of these types of …

Evidence from both human and animal studies has demonstrated a key role for brainstem
centers in the control of ascending nociceptive input. Nuclei such as the rostral ventromedial …

All pain is unpleasant, but different perceptual and emotional qualities are characteristic of
pain originating in different structures. Pain of superficial (cutaneous) origin usually is sharp …

The use of functional brain imaging techniques has led to considerable advances in our
understanding of brain processing of human visceral sensation. The use of complementary …

Pain can be very intense or only mild, and can be well localized or diffuse. To date, little is
known as to how such distinct sensory aspects of noxious stimuli are processed by the …

This functional magnetic resonance imaging study addressed similarities and differences in
behavioral and neural responses to experimental visceral compared with somatic pain …

Pain is a diverse sensory and emotional experience that likely involves activation of
numerous regions of the brain. Yet, many of these areas are also implicated in the …
