Other brainstem pathways, such as the spinothalamic tract or dorsal columns, could also produce MEP suppression, although examination of their contribution is beyond the scope of this paper.
Some function usually recovers, but whether plasticity of undamaged ipsilaterally descending corticospinal axons and/or brainstem pathways such as the reticulospinal tract contributes to recovery is unknown.
The authors conclude that a protective effect from hard food might involve the opioid system, which is affected by sensory pathways, but perhaps also by other neural pathways, such as the brainstem reticular formation [ 45].
Current spread into the brainstem may additionally activate ascending and descending pathways such as the corticospinal tract (CST).
One reason pain studies have lagged behind is that many of the techniques originally developed cannot be directly implemented to study key relay sites within pain pathways, such as the skin, dorsal root ganglia, spinal cord, and brainstem.
In addition to the Smad pathway, BMP-6 is also known to activate and cross-talk with other pathways, such as the MAPK pathway 11.
However, other pathways, such as the PI3K-Akt signaling pathway, Wnt signaling pathway, ECM-receptor interaction and ABC transporters, were also significantly enriched (Sup Fig. 2).
According to the studies of PAH-degrading pure cultures, PAHs can be degraded via several downstream pathways, such as catechol pathway, gentisic acid pathway and protocatechuic acid pathway.
"We offer students access to the school nurse and if necessary, pathways such as the smoke cessation program".
And cancer-related pathway, such as HIF and WNT pathways, may contribute to altered iron metabolism in cancer93.
Projections of the amygdala to brainstem areas such as the LC were proposed as instrumental in the detection of and orienting to visceral signals of emotions [13].
