The organization of the efferent projections from the pontine parabrachial (pPB) area to the amygdala has been studied in the rat by using microinjections of Phaseolus vulgaris leucoagglutinin…
Diffuse noxious inhibitory controls (DNIC). II. Lack of effect on non-convergent neurones, supraspinal involvement and theoretical implications
The spino(trigemino)pontoamygdaloid pathway: electrophysiological evidence for an involvement in pain processes.
Neurons recorded in the parabrachial (PB) area, located in the dorsolateral region of the pons, in the anesthetized rat exhibited a clear capacity to encode thermal stimuli in the noxious range.
A limited arthritic model for chronic pain studies in the rat
Physiological properties of the lamina I spinoparabrachial neurons in the rat.
The nociceptive properties of the lamina I spino-PB neurons are reflected largely by those of PB neurons that were suggested to be involved in autonomic and emotional/aversive aspects of pain.
The parabrachial area: electrophysiological evidence for an involvement in visceral nociceptive processes.
The visceral activated neurons exhibited a clear capacity to encode the colorectal distension in noxious range and were activated by thermal and/or mechanical cutaneous noxious stimuli while only 16% of them were activated only by visceral noxious stimulation.
Spinal Substance P Receptor Expression and Internalization in Acute, Short-Term, and Long-Term Inflammatory Pain States
The results suggest that SPR internalization might serve as a marker of the contribution of ongoing primary afferent input in acute and persistent pain states, and suggest that there are unique neurochemical signatures for acute, short-term, and long-term inflammatory pain.
