Optic afferents to the parabrachial nucleus.
Following intraocular injection of cholera toxin subunit B (CTB), optic afferents to the dorsal pontine region were observed in Mongolian gerbils, Chilean degus, and laboratory rats. CTB-positive optic axons emerge at the caudal pole of the superior colliculus, descend through the periaqueductal gray, and innervate the lateral parabrachial nucleus. This projection appears to be a continuation o...
متن کاملResponses of primate caudal parabrachial nucleus and Kölliker-fuse nucleus neurons to whole body rotation.
The caudal aspect of the parabrachial (PBN) and Kölliker-Fuse (KF) nuclei receive vestibular nuclear and visceral afferent information and are connected reciprocally with the spinal cord, hypothalamus, amygdala, and limbic cortex. Hence, they may be important sites of vestibulo-visceral integration, particularly for the development of affective responses to gravitoinertial challenges. Extracell...
متن کاملModulation of carotid sinus afferent input to nucleus tractus solitarius by parabrachial nucleus stimulation.
There is increasing evidence that the parabrachial nucleus (PBN) may be integrally involved in cardiovascular reflex regulation. In cats in which anesthesia was induced with pentobarbital and maintained with alpha-chloralose, we studied the effects of PBN stimulation on cardiovascular afferent inputs to nucleus tractus solitarius (NTS), the site of first central termination for cardiovascular a...
متن کاملParabrachial nucleus modulates cardiovascular responses to blood loss.
The goal of this study was to determine the role of the pontine lateral parabrachial nucleus (LPBN) in the compensatory responses to blood loss. Conscious unrestrained rats with complete, partial, or sham bilateral ibotenic acid lesions of the LPBN were subjected to a hypotensive 16-ml/kg blood withdrawal via arterial catheter. Complete lesions (LPBNx) encompassed the entire LPBN and extended i...
متن کاملLateral parabrachial nucleus and angiotensin II-induced hypertension.
The objective of this study was to determine if ablation of the lateral parabrachial nucleus (LPBN) would prevent angiotensin II-induced hypertension in rats. Thirteen male Sprague-Dawley rats were studied. Bilateral electrolytic lesions in the LPBN were produced in six rats; the remaining seven rats were subjected to sham lesion surgery only. All rats were instrumented with vascular catheters ...
