(b) The gigantocellular reticular nucleus
(Gi) and the nucleus raphe magnus + gigantocellular reticular nucleus
pars alpha (GiA + NRM).
These thalamic nuclei, along with the intralaminar nuclei and the thalamic reticular nucleus
, which is discussed below, are thought to be essential for higher levels of consciousness (e.g., Steriade et al., 1996; Llinas et al., 1998, 2005; Steriade, 2006) In Figure 3, the main collothalamic pathways are shown as relays from the colliculi to the thalamus; the visual and somatosensory/multisensory pathways are shown as running together from the superior colliculus, and the main auditory pathway is shown as running from the inferior colliculus.
The accuracy of tracer injections into the right Gi reticular nucleus
to label the RtST was also verified (Figure 1(b)).
In normal mice, a compound known to block the benzodiazepine-binding site weakened these same receptors' inhibitory activity in the thalamic reticular nucleus
, even in the absence of any administered benzodiazepines.
(161.) De La Roza C, Martinez-Mena J, Sanchez-Valle ME, ReinosoSuarez E Projections from the cat posterior lateral hypothalamus to the ventral part of the oral pontine reticular nucleus
contain a GABAergic component.
The vegetative effects of visceral-cardiac-respiratory centers being stimulated in pain are evident; as already mentioned, these can be anti-nociceptive and pro-nociceptive from craniofacial pain stimulus in pain facilitating centers, such as the dorsal-medullar reticular nucleus
ultimately forging a balance of joint antagonic modulations in perceiving pain (Almeida et al.).
