(FRAME-INFO (STRING "General Visceral Afferents \(Cranial Nerves VII, IX, and  X\).  General visceral afferents play a role in the control of the autonomic and endocrine systems \(for example, in respiratory, cardiovascular and swallowing reflex connections in the brainstem reticular formation, and via the hypothalamus and amygdala\). Primary visceral afferents travel in the solitary tract to the solitary nucleus, particularly its caudal part. This figure shows a connection from the solitary nucleus \(yellow\) in the medulla \(at bottom\) to the parabrachial nucleus \(green\) in the rostral pons \(at top\).  The parabrachial nucleus projects to the hypothalamus and amygdala. There is also evidence that it projects to the thalamus, near the gustatory part of the ventral posterior medial nuclear complex, and thence to the posterior part of the  insula for visceral sensation.  Links from the solitary nucleus to the dorsal motor nucleus of the vagus \(blue\) and to the reticular formation \(blue\) in the medulla are also shown; many others are possible."))
