Sep 27th, 2022 - Myocardial sleeves around pulmonary veins (PVs) are highly innervated structures with heterogeneous morphological and electrophysiological characteristics. Autonomic nerve dysfunction in the myocardium may be associated with an increased risk of cardiovascular morbidity and mortality. This article studied autonomic neural remodeling in myocardial sleeves around PVs and atrial-PV ostia with immu...

https://doi.org/10.1053/j.sult.2022.04.008
Seminars in Ultrasound, CT, and MR; Lucio LL, Freddi TAL et. al.

Sep 19th, 2022 - The abducens, or the sixth cranial nerve, is purely motor and runs a long course from the brainstem to the lateral rectus. Travels with the inferior petrosal sinus through the Dorello's canal before entering the cavernous sinus. Based on the location of an abnormality, other neurologic structures may be involved with the disturbs related to this nerve. This article aims to review the abducens n...

https://doi.org/10.1053/j.sult.2022.04.009
Seminars in Ultrasound, CT, and MR; Corrêa DG, Hygino da Cruz LC et. al.

Sep 19th, 2022 - The oculomotor nerve is the third cranial nerve, exiting the brainstem in the medial border of the cerebral peduncle, from where it crosses straight to the superior orbital fissure. It is a purely motor nerve responsible for the innervation of all the extraocular muscles, except the superior oblique and lateral rectus muscles. It also has parasympathetic pre-ganglionic fibers, responsible for t...

Proceedings of the National Academy of Sciences of the Un... Filova I, Pysanenko K et. al.

Sep 9th, 2022 - A cardinal feature of the auditory pathway is frequency selectivity, represented in a tonotopic map from the cochlea to the cortex. The molecular determinants of the auditory frequency map are unknown. Here, we discovered that the transcription factor ISL1 regulates the molecular and cellular features of auditory neurons, including the formation of the spiral ganglion and peripheral and central...

https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9477745
Nature Wang Y, Leung VH et. al.

Sep 1st, 2022 - Adipose tissues communicate with the central nervous system to maintain whole-body energy homeostasis. The mainstream view is that circulating hormones secreted by the fat convey the metabolic state to the brain, which integrates peripheral information and regulates adipocyte function through noradrenergic sympathetic output1. Moreover, somatosensory neurons of the dorsal root ganglia innervate...

Hand Clinics; Tang JB

Aug 20th, 2022 - This article discusses ulnar, median, and radial nerve compression in the proximal forearm and elbow and some possible common misconceptions. In particular, the ligament of Struthers extremely rarely causes ulnar neuropathy. Lacertus syndrome and flexor superficialis-pronator syndrome can be diagnosed separately. Surgical release can be through a small incision. Acronyms for compression to radi...

https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9280742
World Journal of Gastroenterology; Yang JM, Yang XY et. al.

Aug 19th, 2022 - Cholinergic nerves are widely distributed throughout the human body and participate in various physiological activities, including sensory, motor, and visceral activities, through cholinergic signaling. Cholinergic signaling plays an important role in pancreatic exocrine secretion. A large number of studies have found that cholinergic signaling overstimulates pancreatic acinar cells through mus...

https://doi.org/10.1007/s00276-022-03006-6
Surgical and Radiologic Anatomy : SRA; Torun Bİ, Balaban M

Aug 17th, 2022 - The Gantzer's muscle is considered to be the accessory head of the flexor pollicis longus. The prevalence of the Gantzer's muscle and its anatomical relations vary in the literature. So, we aimed to study its prevalence and anatomical relations on a broad population on magnetic resonance (MRI) and ultrasound (US) images. We investigated a total of 473 upper extremities of 378 people (171 women,...

Handbook of Clinical Neurology; Taylor-Clark TE, Undem BJ

Aug 15th, 2022 - Airway function is under constant neurophysiological control, in order to maximize airflow and gas exchange and to protect the airways from aspiration, damage, and infection. There are multiple sensory nerve subtypes, whose disparate functions provide a wide array of sensory information into the CNS. Activation of these subtypes triggers specific reflexes, including cough and alterations in aut...

https://doi.org/10.1016/B978-0-323-91534-2.00012-6
Handbook of Clinical Neurology; Fuller DD, Rana S et. al.

Aug 15th, 2022 - The phrenic neuromuscular system consists of the phrenic motor nucleus in the mid-cervical spinal cord, the phrenic nerve, and the diaphragm muscle. This motor system helps sustain breathing throughout life, while also contributing to posture, coughing, swallowing, and speaking. The phrenic nerve contains primarily efferent phrenic axons and afferent axons from diaphragm sensory receptors but i...

Journal of Neuroscience Research; Sinopoulou E, Spejo AB et. al.

Aug 3rd, 2022 - Cervical level spinal cord injury (SCI) can severely impact upper limb muscle function, which is typically assessed in the clinic using electromyography (EMG). Here, we established novel preclinical methodology for EMG assessments of muscle function after SCI in awake freely moving animals. Adult female rats were implanted with EMG recording electrodes in bicep muscles and received bilateral ce...

https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9371718
Proceedings of the National Academy of Sciences of the Un... Motomura H, Ioroi M et. al.

Aug 2nd, 2022 - Animals maintain the ability to survive and reproduce by acclimating to environmental temperatures. We showed here that Caenorhabditis elegans exhibited temperature acclimation plasticity, which was regulated by a head-tail-head neural circuitry coupled with gut fat storage. After experiencing cold, C. elegans individuals memorized the experience and were prepared against subsequent cold stimul...
