Several motor and sensory nuclei form longitudinal columns in the brainstem, leading to some authors describing them as single discontinuous longitudinal nuclear columns rather than the more numerous individual separate nuclei. (radiopaedia.org)
Hypothalamus3
6 POMC neurons project axonal processes to second-order neurons in hypothalamic areas such as the paraventricular nucleus (PVN), ventromedial hypothalamus (VMH) and lateral hypothalamus (LH), and to autonomic preganglionic neurons in the brain stem and spinal cord. (nature.com)
The paraventricular nucleus (PVN) of the hypothalamus has been implicated in autonomic regulation. (queensu.ca)
The arcuate nucleus (ARC) of the hypothalamus, which is located between the third ventricle and the median eminence, integrates these energy homeostatic feedback mechanisms. (medscape.com)
Brainstem nuclei4
Extensive interconnections exist between many of these nuclei, as well as with other brainstem nuclei and white matter tracts, such as the medial lemniscus and medial longitudinal fasciculus . (radiopaedia.org)
Some stressors involve an immediate threat to physiological homeostasis and require the rapid relay of peripheral signals to PVN neurons via direct serotonergic or catecholaminergic projections from brainstem nuclei [ 9 , 11 ]. (nature.com)

This area is a bit below the autonomic motor nuclei, and includes the nucleus ambiguus, facial nerve nucleus, as well as the motor part of the trigeminal nerve nucleus. (wikipedia.org)
Tractus solitarius2
Cranial visceral afferents, which innervate the heart and lungs, synapse centrally onto neurons within the medial portion of the nucleus tractus solitarius (NTS). (silverchair.com)
Nucleus tractus solitarius (NTS) is the central integration hub for afferents from upper airway (somatosensory/gustatory), respiratory, gastrointestinal, cardiovascular (baroreceptor and chemoreceptor) and other systems. (hindawi.com)

Special visceral1
Another area, not on the dorsum of the brainstem, is where the special visceral efferents nuclei reside. (wikipedia.org)
Cranial nerves4
Through the center of the SN runs the solitary tract, a white bundle of nerve fibers, including fibers from the cranial nerves VII, IX, and X. Cell bodies of the SN are roughly somatotopically arranged along its length according to function: for instance, cells involved in taste are located in the rostral part, while those receiving information from cardio-respiratory and gastrointestinal processes are found in the caudal part. (wikipedia.org)
Axons carrying information to and from the cranial nerves form a synapse first at these nuclei. (wikipedia.org)
Other nuclei, however, are long and span several regions of the brainstem contributing to several cranial nerves. (radiopaedia.org)
Receptors3
