Imaging pain: a potent means for investigating pain mechanisms in patients
Chronic pain is a state of physical suffering strongly associated with feelings of anxiety, depression and despair. Disease pathophysiology, psychological state, and social milieu can influence chronic pain, but can be difficult to diagnose based solely on clinical presentation. Here, we review brain neuroimaging research that is shaping our understanding of pain mechanisms, and consider how su...

متن کاملVicarious pain while observing another in pain: an experimental approach
OBJECTIVE This study aimed at developing an experimental paradigm to assess vicarious pain experiences. We further explored the putative moderating role of observer's characteristics such as hypervigilance for pain and dispositional empathy. METHODS Two experiments are reported using a similar procedure. Undergraduate students were selected based upon whether they reported vicarious pain in d...
متن کاملStimulus methods for recording pain-related SEF
1. Introduction The cerebral representation of pain perception in humans is poorly understood compared with that of other sensations such as touch or vibration. This is mainly because of a lack of appropriate instrumentation for stimulation and recording [1]. To our knowledge, only a few systematic studies of somatosensory evoked magnetic field (SEF) following painful stimulation (pain-related ...
متن کاملPain without Nociceptors? Nav1.7-Independent Pain Mechanisms
Nav1.7, a peripheral neuron voltage-gated sodium channel, is essential for pain and olfaction in mice and humans. We examined the role of Nav1.7 as well as Nav1.3, Nav1.8, and Nav1.9 in different mouse models of chronic pain. Constriction-injury-dependent neuropathic pain is abolished when Nav1.7 is deleted in sensory neurons, unlike nerve-transection-related pain, which requires the deletion o...
