Using the aluminium-formaldehyde method for visualization of catechlamines in
combination with injections of the fluorescent retrograde tracer True Blue we have studied …

Sensory and pain thresholds to electrical stimulation of tooth pulps were measured in
normotensive and essential hypertensive unmedicated human subjects. In both adult and …

The mu (μ) opioid receptors, which mediate the effects of morphine, are widely distributed in
brain. We have examined the distribution of mRNA encoding a μ opioid receptor in rat brain …

Pain perception is decreased by shifting attentional focus away from a threatening event.
This attentional analgesia engages parallel descending control pathways from anterior …

The organization in the brainstem of descending pathways of spinal inhibition was
examined in the lightly pentobarbital-anesthetized rat. Thresholds for focal electrical …

Cholecystokinin octapeptide-like (CCK-OP-like) immunoreactivity was localized in the rat
brain by using the indirect immunofluorescence method. Specificity in immunohistochemical …

The localization of serotonergic, various peptidergic and possibly cholinergic neurons in the
medullary raphe nuclei that project to the lumbosacral spinal cord have been studied using …

The sickness-inducing agents lithium chloride (LiCl) and lipopolysacharide (LPS) produce a
long-lasting facilitation of the nociceptive tailflick reflex. Many of the behavioral and …

The effects of placebo and varying doses of intravenous morphine were studied in 74
patients. All patients underwent extraction of impacted mandibular third molars. Two hours …

Spinal cord stimulation (SCS) may alleviate certain forms of neuropathic pain; its
mechanisms of action are, however, not fully understood. Previous studies have mainly …
