Inhibitory neurons in the spinal cord perform dedicated roles in processing somatosensory information and shaping motor behaviors that range from simple protective reflexes to more complex motor tasks such as locomotion, reaching and grasping. Recent efforts examining inhibition in the spinal cord have been directed toward determining how inhibitory cell types are specified and incorporated into the sensorimotor circuitry, identifying and characterizing molecularly defined cohorts of inhibitory neurons and interrogating the functional contribution these cells make to sensory processing and motor behaviors. Rapid progress is being made on all these fronts, driven in large part by molecular genetic and optogenetic approaches that are being creatively combined with neuroanatomical, electrophysiological and behavioral techniques.

Outcomes and complications of vertebral body tethering by patient gender.
Spine Deform
January 2025
Department of Orthopedic Surgery, Mayo Clinic, 200 First Street S.W, Rochester, MN, 55906, USA.
Purpose: Non-fusion surgical options for pediatric scoliosis management such as vertebral body tethering (VBT) offer an alternative to spinal fusion. With this study, we aim to evaluate the postoperative outcomes in boys versus girls who have undergone VBT. Our hypothesis is that girls and boys will have similar outcomes by 2-year follow-up.

Cognitive impairment (CI) in multiple sclerosis (MS) is only partially explained by whole-brain volume measures, but independent component analysis (ICA) can extract regional patterns of damage in grey matter (GM) or white matter (WM) that have proven more closely associated with CI. Pathology in GM and WM occurs in parallel, and so patterns can span both. This study assessed whether joint-ICA of GM and WM features better explained cognitive function compared to single-tissue ICA.

Department of Spine Surgery, Lishui Hospital of Wenzhou Medical University, Lishui People's Hospital, Lishui, Zhejiang, China.
At present, the choice of approach for the surgical treatment of cervical ossification of the posterior longitudinal ligament (OPLL) remains controversial. We performed this meta-analysis to compare the efficacy of the anterior and posterior approaches in the treatment of cervical OPLL. PubMed, EMBASE and the Cochrane Library were systematically searched for all eligible articles as of August 3, 2023, without any publication date restrictions.

January 2025
Department of Pediatrics, West China Second University Hospital, Sichuan University, Chengdu, 610041, China.
Background: Tourette syndrome (TS) is a prevalent neurodevelopmental disorder with an uncertain etiology. Numerous neuroimaging studies have investigated patients with TS, but their conclusions remain inconsistent. The current study attempted to provide an unbiased statistical meta-analysis of published neuroimaging studies of TS.

Department of Neurology, School of Medical Sciences, University of Campinas-UNICAMP, Universitaria "Zeferino Vaz", Rua Tessália Vieira de Camargo, 126. Cidade, Campinas, SP, 13083-887, Brazil.
Background: Skeletal and cardiac muscle damage have been increasingly recognized in female carriers of DMD pathogenic variants (DMDc). Little is known about cognitive impairment in these women or whether they have structural brain damage.
Objective: To characterize the cognitive profile in a Brazilian cohort of DMDc and determine whether they have structural brain abnormalities using multimodal MRI.
