The neural pathways followed by sensory fibers from arterial baroreceptors in the aortic region of the dog were investigated with neurophysiological recording. Systemic arterial baroreceptor fibers separate from the depressor nerve were found in the left cervical vagus in each of five dogs investigated; at most two fibers were isolated from each dog due to the difficulty of the dissection. Thes...

Granulosis Rubra Nasi (GRN) is a rare disorder of the eccrine glands. It is clinically characterized by hyperhidrosis of the central part of the face, most commonly on the tip of the nose, followed by appearance of diffuse erythema over the nose, cheeks, chin, and upper lip. It is commonly seen in childhood but it can present in adults. Here we report a case of GRN in an adult patient with very...

The septum pellucidum is a non-neural dual membrane structure originating from the medial parts of the cerebral hemispheres. Right and left leaves of the septum are separated by a cavity in fetal life, which gradually becomes thinner and obliterated. Its posterior extension is the cavum vergae. The roof is formed by the corpus callosum and the hippocampal commissure, and posterior and inferior ...

Exposure to panic symptoms (interoceptive exposure) is often included as part of treatment for panic disorder (PD), although little is known about the relative effects of particular symptom induction exercises. This study describes responses of individuals with PD and nonclinical controls to 13 standard symptom induction exercises and 3 control exercises. Generally, individuals with PD responde...

Intravenous administration Gf TP produced an abrupt, transient, reproducible and dose-dependent fall in systemic blood pressure of urethane anaesthetised rats, rabbits and cats. In guinea pigs the effect was found to vary from animal to animal. Whereas in some guinea pigs, TPN provoked biphasic, pressor-depressor response; in others either of the pressor or depressor responses was obtained. Vag...

The thrust for jumping in froghopper insects is produced by a rapid, synchronous depression of both hind legs generated by huge, multipartite trochanteral depressor muscles in the thorax and smaller levator muscles in the coxae. A three-phase motor pattern activates these muscles in jumping. First, a levation phase lasts a few hundred milliseconds, in which a burst of spikes in the trochanteral...

Verberne, Anthony J. M., Daniela M. Sartor, and Ayse Berke. Midline medullary depressor responses are mediated by inhibition of RVLM sympathoexcitatory neurons in rats. Am. J. Physiol. 276 (Regulatory Integrative Comp. Physiol. 45): R1054–R1062, 1999.—Mechanisms underlying the depressor and sympathoinhibitory responses evoked from the caudal medullary raphe (MR) region were investigated in pent...

We examined the contribution of the renal nerves to mean arterial pressure (MAP) during 5-week chronic infusion of angiotensin II (Ang II; 50 ng/kg per minute SC) in conscious rabbits. Basal MAP was 68+/-1 mm Hg, and the maximum depressor response to ganglion blockade was -20+/-2 mm Hg. MAP increased by 25+/-2 mm Hg after 1 week and remained stable over the next 4 weeks. Depressor responses to ...

The depressor response to electrical stimulation of the spinal cord and the level of calcitonin gene-related peptide (CGRP) mRNA in the dorsal root ganglion (DRG) in the spontaneously hypertensive rat (SHR) was compared with the normotensive Wistar Kyoto rat (WKY) and Wistar rat (WR). The animals were pithed by inserting a stainless-steel rod into the spinal cord. Pithed rats were treated with ...
