Rain Projections from the Medullary Dorsal Reticular Ucleus: an Anterograde and Retrograde Tracing Study N the Rat
bstract—In the last 15 years a role has been ascribed for the edullary dorsal reticular nucleus as a supraspinal pain modlating area. The medullary dorsal reticular nucleus is reciproally connected with the spinal dorsal horn, is populated mainly y nociceptive neurons and regulates spinal nociceptive proessing. Here we analyze the distribution of brain projections rom the medullary dorsal retic...
متن کاملBrain afferents to the medullary dorsal reticular nucleus: a retrograde and anterograde tracing study in the rat.
The medullary dorsal reticular nucleus (DRt) was recently shown to belong to the supraspinal pain control system; neurons within this nucleus give origin to a descending projection that increases spinal nociceptive transmission and facilitates pain perception [Almeida et al. (1999), Eur. J. Neurosci., 11, 110-122]. In the present study, the areas of the brain that may modulate the activity of D...
متن کاملMorphology and Synaptic Organization of Non-Dopaminergic Nigral Projections to the Medio Dorsal Thalamic Nucleus of the Rat, a Study by Anterograde Transport of PHA-L
Background: Mediodorsal (MD) thalamic nucleus, which is considered to take place between extra pyramidal and limbic feedback circuit, receives projective fibers from ventrolateral neurons of reticular part of substantia nigra (SNr). In order to better understand the influence and chemical reaction of these fibers upon MD nucleus, the morphology and synaptology of them were examined in the prese...
متن کاملProjections from the central nucleus of the amygdala to the nucleus pontis oralis in the rat: an anterograde labeling study.
The present study was designed to elucidate the neuronal projections from the amygdala to the nucleus pontis oralis (NPO). We propose that glutamatergic cells in the central nucleus of the amygdala (CNA) activate neurons in the NPO, which is the critical brainstem site that is responsible for the generation and maintenance of active (REM) sleep. Phaseolus vulgaris-leucoagglutinin (PHA-L), an an...
متن کاملProjections from the trigeminal nuclear complex to the cochlear nuclei: a retrograde and anterograde tracing study in the guinea pig.
In addition to input from auditory centers, the cochlear nucleus (CN) receives inputs from nonauditory centers, including the trigeminal sensory complex. The detailed anatomy, however, and the functional implications of the nonauditory innervation of the auditory system are not fully understood. We demonstrated previously that the trigeminal ganglion projects to CN, with terminal labeling most ...
